Abstract
The use of solar energy for the cooking has taken place for the last few decades. This type of cooking has conducted outside the door. But this attempt has been conducted to cook the food inside the kitchen as a conventional cooking type. This cook-friendly device introduces a new solar heat transfer concept for indoor cooking by developing a special types of cooking utensils, i.e., pans and pots. The present study investigated the different parameters associated with the performance of indoor solar cooking systems. During the study of indoor solar cooking, it has been observed that the most important parameters that affect the performance, considering them as independent parameters, are the time duration of the system exposed to the sun, solar intensity, mass flow rate of the working fluid, and the type of working fluid. Also, the performance is measured in terms of output parameters such as the temperature of the pan, pot, and thermal storage system. In this study, a mathematical relationship has developed between these independent parameters and dependent parameters. The ANOVA method is used to develop mathematical relationships. The experimentation has been carried out for different times ranging from 0 to 8 hours, with solar intensity ranging from 100 W/m2 to 800 W/m2 and mass flow rate in lpm (6, 9, and 12) with heat transfer oils such as Therminol 55 and Soyabean Oil. Further, the equation is formulated and established for each independent parameter in terms of the actual factor. The accuracy of the equations was measured in terms of R2 and found to be 0.9615, 0.9629, and 0.9886 for the temperature of the pan, the temperature of the pot, and the temperature of the thermal storage system, respectively.

Published: June 2024

Abstract
Segregation is an important process mainly used in industries during the flow of granular materials. A granular medium is repeatedly collected particles that have different properties like size, shape, and density. Heap formation in the industry occurs if particles with various sizes, forms, material densities or surface properties are made of bulk materials, then they spatially separate during formation of the heap. This paper provides a detailed understanding of segregation dynamics in granular flows within industrial processes. Focusing on the intricate interplay of particle characteristics, mixing phenomena, and heap formation methodology, the review delves into the essential aspects influencing the spatial separation of particles. Granular media, comprising particles with distinct properties such as size, shape, and density, undergo segregation during the flow processes commonly employed in industries. The formation of heaps becomes a consequential outcome when bulk materials consist of particles exhibiting variations in size, shape, material density, or surface properties. The comprehensive analysis within this review encompasses detailed insights into granular material flow, the intricacies of mixing, the mechanisms of segregation, and the profound effects of particle characteristics on these processes. Additionally, the paper scrutinizes various methodologies employed in industrial settings for heap formation, providing a holistic perspective on the key factors influencing segregation dynamics in granular flows. This review aims to contribute valuable insights to researchers, engineers, and practitioners involved in the optimization and control of granular material handling within diverse industrial applications.

Abstract
Friction Coefficient (FC), Rate of specific wear (RSW) of low carbon steel of grade AISI 1018 overlayed with nickel-based MMC plus WC using laser cladding were investigated in this tribological study. Specimens were pressed up on to a rotating steel disc (EN31), experiments were conducted on low carbon steel and low carbon steel overlayed with nickel-based MMC plus WC on a pin-on-disc machine. MMC based on nickel were layered over low carbon steel using the laser cladding process. A set of samples were used in the experiments, which lasted 20 minutes and involved loading conditions of 10N, 20N, 30N, 40N, and 50N with sliding distances ranging from 1000 m to 3000 m. The findings demonstrate how different loads and sliding distances affect the SWR and CoF. Generally, speaking, CoF rises during the rubbing phase and then stays steady for the duration of the test. The obtained results indicate that, for cladded material, the FC and RSW increase with increasing applied load and sliding distance.RSW and FC of Low Carbon Steel overlayed with Nickel based MMC plus WC, which was created using the Laser Cladding Process, decreased. When compared to low carbon steel, the RSW of low carbon steel overlayed with nickel-based MMC plus WC that was created using laser cladding decreased to 31.26%. CoF of low carbon steel covered with MMC plus WC based on nickel, created by laser cladding, is found to be 12.13% lower. To investigate the worn surfaces of the base metal, a Scanning Electron Microscope (SEM) was used, which is low carbon steel and low carbon steel layered with nickel-based MMC plus WC using laser cladding. Two types of samples had worn surfaces with shallow and fine grooves at low loads, and large quantities of cracks at high loads, which raised weight loss.

Published: June 2024

Abstract
This study examines the use of hybrid and normal nano cutting fluids in drilling, a process commonly used by sectors of the economy that normally depend on gulf cut or dry cut oil. These lubricants work well for drilling, but they don’t improve surface smoothness enough and might shorten the tools lifespan. In order to mitigate these problems, scientists are investigating nanofluids as an alternative to conventional lubricants. They are experimenting with different mixtures of nanofluids as a foundation in drilling operations. Multiple investigations demonstrate that the utilization of nanofluid as cutting fluid can improve lubrication as well as cooling in comparison to conventional cutting fluids. Various drilling techniques, such as dry machining, minimum quantity of lubrication, and solid lubricant, are employed however literature suggests that MQL is the most environmentally friendly option. Given that drilling involves working on tough surfaces, it is imperative to have a high-quality coolant lubricant. While there are several choices available for base lubricants, none of them can achieve the required level of surface finish during drilling. As a possible lubricant option in the future, the research suggests using a hybrid nanofluid in combination with multiple base lubricants.

Published: June 2024

Abstract
This study focuses on investigating the hydrodynamics using computational fluid dynamics (CFD) simulation and residence time distribution (RTD) within a trickle bed reactor (TBR). CFD simulation was performed on a packed column filled with structured packing of glass beads, while the experiments for RTD studies were conducted in a TBR filled with random packing of Raschig rings. The geometry of TBR and size of packing during CFD simulation was kept close to that of the experimental setup. CFD simulation results were obtained which predicted the flow of fluid through the TBR at different vertical planes along the column. The fluctuations of liquid velocity at various positions inside the reactor were predicted by the CFD model. RTD studies were performed for both pulse input and step input using a non-reactive tracer such as sodium hydroxide. The flowrate of water was varied from 0.6 LPH to 6 LPH for pulse input, while for step input the ratio of water to tracer flowrates was kept at 1:1, 1:2 and 2:1. This study allows us to understand how hydrodynamics and residence time distribution may have an effect on the performance of TBR.

Published: June 2024

Abstract
Vibration-related failures more frequently occur than material failures, analysis is crucial to the design of composite leaf springs. It must also have an outstanding fatigue life and be lightweight. To minimize vertical vibrations, hits, and bumps caused by irregular roads and to ensure a comfortable ride, springs are essential suspension components in automobiles. Hence, the material with the highest strength and lowest longitudinal elastic modulus is ideal for use in leaf springs. In the automotive business nowadays, composite materials primarily replace metal elements. Consequently, it is important to use a hybrid composite leaf spring that evenly distributes graphite, carbon, and glass fibers throughout the resin matrix and has a lower spring rate. Hybrid composite materials offer many advantages over conventional composite materials because they use glass and carbon fibers instead of them. These advantages include maximum strength, minimum longitudinal modulus of elasticity, reduced weight as well as vibration, better packaging, enhanced durability, cost savings, fatigue life, and strain energy capacity. The first use of modal analysis is to determine Eigen-vectors, or mode shapes, and Eigen-values, or natural frequencies. Moreover, random vibration analysis is used to distinguish between smooth and rough vibrations, and harmonic analysis is used to determine the response’s amplitude.

Abstract
With the rapid development of the automobile industry, people’s requirements for automobile handling performance and driving safety are getting higher and higher. As an important automobile power system, four-wheel steering technology can improve the maneuverability, stability, and safety of vehicles by controlling the steering angles of front and rear wheels. Therefore, the design and research of the four-wheel steering system has become one of the hotspots in the field of automotive engineering. In this paper, a two-degree-of-freedom dynamics model is established, and based on the PID control strategy of joint feedback of center-of-mass lateral deflection and traverse angular velocity, the vehicle model of a four-wheeled steering vehicle is constructed by using TruckSim, and the minimum turning radius test, serpentine test, and steering wheel angle step test project are carried out. The results show that compared with the two-wheel steering vehicle, the minimum turning diameter of the four-wheel steering vehicle is reduced by 1/3, which effectively improves the maneuverability at low speeds as well as the safety and stability at high speeds, and has better transient response.
