Aero-spike and aero-disk effects of on wave drag reduction of supersonic flow past over blunt body
Authors: Balusamy Kathiravan , A. Vinothraj , V. Suresh 
Published: January 2024

Purpose
The purpose of this study is to explore the effects of aerospike and hemispherical aerodisks on flow characteristics and drag reduction in supersonic flow over a blunt body. Specifically, the study aims to analyze the impact of varying the length of the cylindrical rod in the aerospike (ranging from 0.5 to 2.0 times the diameter of the blunt body) and the diameter of the hemispherical disk (ranging from 0.25 to 0.75 times the blunt body diameter). CFD simulations were conducted at a supersonic Mach number of 2 and a Reynolds number of 2.79 × 106.

Design/methodology/approach
ICEM CFD and ANSYS CFX solver were used to generate the three-dimensional flow along with its structures. The flow structure and drag coefficient were computed using Reynolds-averaged Navier–Stokes equation model. The drag reduction mechanism was also explained using the idea of dividing streamline and density contour. The performance of the aero spike length and the effect of aero disk size on the drag are investigated.

Findings
The separating shock is located in front of the blunt body, forming an effective conical shape that reduces the pressure drag acting on the blunt body. It was observed that extending the length of the spike beyond a specific critical point did not impact the flow field characteristics and had no further influence on the enhanced performance. The optimal combination of disk and spike length was determined, resulting in a substantial reduction in drag through the introduction of the aerospike and disk.

Research limitations/implications
To predict the accurate results of drag and to reduce the simulation time, a hexa grid with finer mesh structure was adopted in the simulation.

Practical implications
The blunt nose structures are primarily employed in the design of rockets, missiles, and re-entry capsules to withstand higher aerodynamic loads and aerodynamic heating.

Originality/value
For the optimized size of the aero spike, aero disk is also optimized to use the benefits of both.

Authors: Motohashi Kazuyuki , Zhu Chen 
Published: January 2024

Purpose
This study aims to assess the technological capability of Chinese internet platforms (BAT: Baidu, Alibaba, Tencent) compared to US ones (GAFA: Google, Amazon, Facebook, Apple). More specifically, this study explores Baidu’s technological catching-up process with Google by analyzing their patent textual information.

Design/methodology/approach
The authors retrieved 26,383 Google patents and 6,695 Baidu patents from PATSTAT 2019 Spring version. The collected patent documents were vectorized using the Word2Vec model first, and then K-means clustering was applied to visualize the technological space of two firms. Finally, novel indicators were proposed to capture the technological catching-up process between Baidu and Google.

Findings
The results show that Baidu follows a trend of US rather than Chinese technology which suggests Baidu is aggressively seeking to catch up with US players in the process of its technological development. At the same time, the impact index of Baidu patents increases over time, reflecting its upgrading of technological competitiveness.

Originality/value
This study proposed a new method to analyze technology mapping and evolution based on patent text information. As both US and China are crucial players in the internet industry, it is vital for policymakers in third countries to understand the technological capacity and competitiveness of both countries to develop strategic partnerships effectively.

Authors: Sruthilaya Dara , Vilventhan Aneetha , Gopal P.R.C. 
Published: January 2024

PurposeThe purpose of this research is to develop a project complexity index (PCI) model using the best and worst method (BWM) to quantitatively analyze the impact of project complexities on the performance of metro rail projects.Design/methodology/approachThis study employed a two-phase research methodology. The first phase identifies complexities through a literature review and expert discussions and categorizes different types of complexities in metro rail projects. In the second phase, BWM, a robust multi-criteria decision-making (MCDM) technique, was used to prioritize key complexities, and a PCI model was developed. Further, the developed PCI was validated through case studies, and sensitivity analysis was performed to check the accuracy and applicability of the developed PCI model.FindingsThe analysis revealed that location complexity exerted the most substantial influence on project performance, followed by environmental, organizational, technological and contractual complexities. Sensitivity analysis revealed the varying impacts of complexity indices on the overall project complexity.Practical implicationsThe study's findings offer a novel approach for measuring project complexity's impact on metro rail projects. This allows stakeholders to make informed decisions, allocate resources efficiently and plan strategically.Originality/valueThe existing studies on project complexity identification and quantification were limited to megaprojects other than metro rail projects. Efforts to quantitatively study and analyze the impact of project complexity on metro rail projects are left unattended. The developed PCI model and its validation contribute to the field by providing a definite method to measure and manage complexity in metro rail projects.
Numerical simulation of entropy generation in thermo-magnetic convection in an inverted T-shaped porous enclosure under thermal radiation
Authors: Kumar Sumant , Rathish Kumar B.V. , Krishna Murthy S.V.S.S.N.V.G. , Parmar Deepika 
Published: January 2024

Purpose
Thermo-magnetic convective flow analysis under the impact of thermal radiation for heat and entropy generation phenomena is an active research field for understanding the efficiency of thermodynamic systems in various engineering sectors. This study aims to examine the characteristics of convective heat transport and entropy generation within an inverted T-shaped porous enclosure saturated with a hybrid nanofluid under the influence of thermal radiation and magnetic field.

Design/methodology/approach
The mathematical model incorporates the Darcy-Forchheimer-Brinkmann model and considers thermal radiation in the energy balance equation. The complete mathematical model has been numerically simulated through the penalty finite element approach at varying values of flow parameters, such as Rayleigh number (Ra), Hartmann number (Ha), Darcy number (Da), radiation parameter (Rd) and porosity value (e). Furthermore, the graphical results for energy variation have been monitored through the energy-flux vector, whereas the entropy generation along with its individual components, namely, entropy generation due to heat transfer, fluid friction and magnetic field, are also presented. Furthermore, the results of the Bejan number for each component are also discussed in detail. Additionally, the concept of ecological coefficient of performance (ECOP) has also been included to analyse the thermal efficiency of the model.

Findings
The graphical analysis of results indicates that higher values of Ra, Da, e and Rd enhance the convective heat transport and entropy generation phenomena more rapidly. However, increasing Ha values have a detrimental effect due to the increasing impact of magnetic forces. Furthermore, the ECOP result suggests that the rising value of Da, e and Rd at smaller Ra show a maximum thermal efficiency of the mathematical model, which further declines as the Ra increases. Conversely, the thermal efficiency of the model improves with increasing Ha value, showing an opposite trend in ECOP.

Practical implications
Such complex porous enclosures have practical applications in engineering and science, including areas like solar power collectors, heat exchangers and electronic equipment. Furthermore, the present study of entropy generation would play a vital role in optimizing system performance, improving energy efficiency and promoting sustainable engineering practices during the natural convection process.

Originality/value
To the best of the authors’ knowledge, this study is the first ever attempted detailed investigation of heat transfer and entropy generation phenomena flow parameter ranges in an inverted T-shaped porous enclosure under a uniform magnetic field and thermal radiation.
Magnetotactic bacteria and Fe3O4–water in a wavy walled cavity
Authors: Pekmen Geridonmez Bengisen , Oztop Hakan 
Published: January 2024

Purpose
The purpose of this study is to investigate the interaction between magnetotactic bacteria and Fe3O4–water nanofluid (NF) in a wavy enclosure in the presence of 2D natural convection flow.

Design/methodology/approach
Uniform magnetic field (MF), Brownian and thermophoresis effects are also contemplated. The dimensionless, time-dependent equations are governed by stream function, vorticity, energy, nanoparticle concentration and number of bacteria. Radial basis function-based finite difference method for the space derivatives and the second-order backward differentiation formula for the time derivatives are performed. Numerical outputs in view of isolines as well as average Nusselt number, average Sherwood number and flux density of microorganisms are presented.

Findings
Convective mass transfer rises if any of Lewis number, Peclet number, Rayleigh number, bioconvection Rayleigh number and Brownian motion parameter increases, and the flux density of microorganisms is an increasing function of Rayleigh number, bioconvection Rayleigh number, Peclet number, Brownian and thermophoresis parameters. The rise in buoyancy ratio parameter between 0.1 and 1 and the rise in Hartmann number between 0 and 50 reduce all outputs average Nusselt, average Sherwood numbers and flux density of microorganisms.

Research limitations/implications
This study implies the importance of the presence of magnetotactic bacteria and magnetite nanoparticles inside a host fluid in view of heat transfer and fluid flow. The limitation is to check the efficiency on numerical aspect. Experimental observations would be more effective.

Practical implications
In practical point of view, in a heat transfer and fluid flow system involving magnetite nanoparticles, the inclusion of magnetotactic bacteria and MF effect provide control over fluid flow and heat transfer.

Social implications
This is a scientific study. However, this idea may be extended to sustainable energy or biofuel studies, too. This means that a better world may create better social environment between people.

Originality/value
The presence of magnetotactic bacteria inside a Fe3O4–water NF under the effect of a MF is a good controller on fluid flow and heat transfer. Since the magnetotactic bacteria is fed by nanoparticles Fe3O4 which has strong magnetic property, varying nanoparticle concentration and Brownian and thermophoresis effects are first considered.

Authors: Huynh Anh-Tuan , Knápková Adriana , Bui Tat-Dat , Nguyen Tran-Thai-Ha 
Published: January 2024

PurposeInstitutional pressure and corporate social responsibility (CSR) are gaining increasing recognition in scholarly works; however, there is an apparent and unsettled relationship between these concepts and the concept of green marketing adoption (GMA) that influences efforts to gain a relative competitive advantage (RCA). This study is aimed at examining the roles of institutional pressure and CSR on GMA and RCA and proposes recommendations for promoting green marketing management and CSC in the banking industry in Vietnam.Design/methodology/approachIn this study, partial least squares structural equation modeling is utilized to investigate the evolution of the structural model, while the hypotheses are evaluated using structural equation modeling (SEM). The data are scrutinized from 288 banking employees through an online survey.FindingsThe results show that the components of institutional pressure exert a significant impact on GMA and RCA, but the level and type of this impact differ. Additionally, the mediating role of the CSR variable in this relationship is revealed. Under the influence of institutional pressure, companies tend to increase their implementation of CSR activities, thereby promoting their GMA and RCA.Originality/valueThis study offers both theoretical and practical implications. Theoretically, this study adds to the extant evidence concerning the significance of CSR integration and institutional pressure to the advancement of GMA. In addition, maintaining a focus on fostering holistic GMA practices has enabled the banking industry in Vietnam to achieve an RCA.

Authors: Kim Jinkyung Jenny 
Published: January 2024

Purpose
This study aims to pay attention to the brand portfolio extension of international hotel chains, and explores the double-edged sword effect of consumer confusion in hotel brands on the purchase decision process.

Design/methodology/approach
Four representative international hotel chains (Marriott, Accor, Wyndham and Hyatt) were selected, and this study adopted consumer confusion from both formative and reflective perspectives. First, the authors dealt with stimuli-causing consumer confusion and evaluated similarity, overload and ambiguity confusion about the brand portfolio of these major hotel companies. Second, the authors examined the influence of consumer confusion on the decision-making process, which is rooted in the awareness–interest–desire–action model.

Findings
Among the source of consumer confusion, similarity confusion was critical for Marriott, Accor and Hyatt, whereas ambiguity confusion was severe for Wyndham. Awareness was positively affected by overload confusion, but negatively affected by ambiguity confusion. Furthermore, the link between interest and desire was moderated by the consequences of consumer confusion.

Practical implications
Based on both positive and negative roles of consumer confusion, this study provides implications for enhancing brand strategy and communications of international chain hotels.

Originality/value
This present study differs from previous studies, in that it deals with consumer confusion associated with brand portfolio expansion, which produces a double-edged sword effect in the hotel context.
Wait time speeds up: effects of scent arousal on time perception in service marketing
Authors: Yu Ziyue , Yang Shuai , Liu Yahui , Xie Yujia 
Published: January 2024

PurposeThis study examines the effects of scent arousal on consumers' time perception in retail service environments and further explores how the effect is moderated by consumer-perceived stress.Design/methodology/approachA laboratory experiment (Study 1) and a field experiment (Study 2) were conducted to examine the relationship between scent arousal and time perception and the mediating effect between scent arousal and consumers' store evaluations. Another laboratory experiment (Study 3) was conducted to explore how consumers' stress modifies the scent arousal effect.FindingsConsumers in a low-arousal scent condition perceived a shorter duration of time than those in a high-arousal scent condition. This finding was verified in a field experiment, whereas scent arousal affects consumers' store evaluations through the mediating effects of time perception. However, the impact of scent arousal on time perception was attenuated in high-stress conditions.Originality/valueTime duration perception is an important indicator in the retail service marketing process. Evidence shows that underestimating time duration in the shopping process represents positive responses. This study extends prior research by examining how scent arousal influences time perception and how consumers' stress moderates scent arousal’s effect.
Tourism representation and strategies on public signs: linguistic landscape of a Saudi southern tourist destination
Authors: Hazaea Abduljalil Nasr , Al-Sofi Bakr Bagash Mansour Ahmed , Alfaifi Abdullah 
Published: January 2024

Purpose
This study aims to investigate multilingual representation on public signs in the High City tourist destination in Abha, Saudi Arabia. It also reveals the linguistic strategies used in such representation.

Design/methodology/approach
This exploratory qualitative study used purposive sampling to analyze bottom-up public signs collected from the target tourist destination. A preliminary analysis was conducted for a more in-depth qualitative analysis of every sign. An Excel database was used to provide a general description and a preliminary reading of the strategies before using an in-depth analysis of every sign.

Findings
The study revealed that monolingualism (Arabic or English) and bilingualism (Arabic and English) represented the High City as a tourist destination where the signs served information and symbolic functions. No single multilingual sign was found. Certain linguistic strategies were used on the public signs, including politeness, transliteration, hybrid representation, personification and fragmentary. Some tourist-oriented strategies, such as the crisis communication strategy, are still missing.

Practical implications
These findings indicate that this tourist destination still targets local and regional visitors, and its linguistic landscape (LL) needs further consideration in terms of internationalization and targeting international visitors. This study implies that bilingual Arabic and English tourist destinations are potential domains for translation students and English language learners.

Originality/value
This study has focused on the LL of a newly established tourist destination in Saudi Arabia. It has shed light on the nuanced representations and strategies used through public signage. It contributes to understanding how linguistic elements can shape tourists’ perceptions and experiences.
