Authors: Ghazaly Nouby M. , Moaaz Ahmad O. , Makrahy Mostafa M.
Published: January 2023

The methods of short-time Fourier transform (STFT) signal processing have been used to enhance the condition monitoring of machines. It can be better to use in reciprocating machines such as internal combustion engines, as the signal is non-stationary. The FFT usage wouldn’t be beneficial in this case as it treats stationary signals such as those captured from rotating machines. The vibration of machines became challenging, as for the engine, pack up, faults in such complex systems can lead to frequency alternation and amplitude. In the present study, the vibration signal was acquired from the engine at the vicinity of the piston 2 and 3 to get acceptable signal intensity. The normal state is measured at idle speed condition and two other speeds 2000 and 3000 rpm. Three faults are investigated namely; misfire of one cylinder, two cylinder misfire and ignition timing. Then, the signal processed using STFT was used to distinguish and detect fault using vibration signal. The output signals were exported to MATLAB for further analysis. The experimental results revealed that the normal condition had more vibration than one cylinder misfire than two cylinder misfire due to the damping effect. In addition, the vibration levels at ignition timing (3 BTDC), (3 ATDC), (6 BTDC) and (6 ATDC) were recorded as maximum when compared to normal condition at 5 BTDC.

The occupants of an automobile are subjected to varying levels of vibration, which may not affect them consciously, but passively these are found to contribute to lower back pain, dizziness and discomfort amongst other health hazards when exposed for a chronic period. The primary source of these vibrations apart from the ones originating from the engine, are transmitted from the road during tire road interaction. The effect of this is felt by the occupants via the seat, foot rest, back rest and steering wheel of a four wheeler and the handlebar, footrest and seat in case of a two wheeler. The international standards such as ISO 2631-1:1997 for whole body are followed by vehicle manufacturers for ensuring ride comfort in terms of vibration transmissibility to the occupants. The ride comfort of a vehicle is influenced by the natural and force transfer characteristics of the tire wheel assembly and the suspension system. The objective of the current work is to use analytical models for finding natural frequencies of sprung and unsprung mass and henceforth determining the trend of vibration amplitude influenced by parameters like damping, mass and stiffness values through a forced response analysis. Subsequently, experiments are conducted to measure the real time vibration levels at aforementioned human interaction points. This helps to correlate the analytical study with the experimental outcomes.

A large part of todays technology is automated and controlled by computer systems. Intervention using an automation and control system has the added benefit of reducing the need for human intervention. But it can also be employed in order to conserve resources and increase the quality, precision, and accuracy of products. As a result of these advantages, automated and regulated systems are now utilized throughout a wide range of industries. Our primary goal is to construct an engine control system that will help to prevent the engine overheating, as well as to enhance vehicle safety by digitally locking the fuel. In addition to the sensors, the solenoid valve and the fuel pump make up the majority of this signal and engine closure. The operating temperature of the engine is detected using a temperature sensor that is mounted to the engine. When the engine temperature rises over a predetermined threshold, the microprocessor instructs the solenoid valve to shut off the fuel supply to the engine, which generates a signal. The microcontroller receives a signal from the float sensor, which detects the fuel level. The rider will be aware that there is an issue with the engine and this method will prevent the engine overheating.

Published: January 2023

In pressure vessel and pipe systems, gasketed flange joints are quite frequent and are also used in oil and gas wellheads and trees as spool end connections. Flanges are most commonly employed when a joining or disassembling junction is required. The process industry has long been concerned about leakage in gasketed flanged junctions. The installation and stress factors of a gasketed flange joint directly affect its sealing effectiveness. API 6A type 6B flange with a maximum pressure rating of 20,000 psi is examined in this study using API design procedures. Due to the symmetricity of the 8 bolted flange, a 45 section is taken for analysis. The findings of a parametric analysis of flange behaviour and bolt stresses are investigated by altering the bolt preload and internal pressure while keeping other flange independent variables constant.

This paper forecasts the transient thermal temperature history during girth welding with a single pass over the welded area on pipe ASME class 300 flange joints of low carbon steel using the moving heat source extension model. Using ANSYS ACT extension for the model of the moving, heat source is simulated for the forecast of the distribution of temperature over the welded region during the welding process like gas metal arc welding. Then due to the residual stress induced by the thermal load of the welding, heat source on the joints is analysed and then comparison of the various heat distribution by changing welding parameters is analysed for optimal welding parameters to reduce the stress. The analysis was carried out on transient thermal and transient structural processes to predict the temperature distribution and residual stress respectively.

Published: January 2023

The fuel consumption rate has been increased in our world compared to older days. Most of the fuels which we use are fossil fuel which has high emissions of greenhouse gases which leads to pollution and global warming. Fuels are getting higher price range nowadays. So, we are trying to find a better alternative fuel which will be cost efficient and less harmful to the planet. In this study we try to solve the problem by experimenting and evaluating the mixture of oils which may reduce emissions of harmful gases. In this project we are using corn oil, rice bran oil with additives and mixing them with conventional fuel i.e., diesel to convert the collected oils into a biodiesel. This process is commonly known as transesterification. The biodiesels are mixed in three different forms like B30, B40, and B50, in which B30 contains 70% of diesel and 15% of corn oil and 15% of rice bran oil. B40 contains 60% of diesel, 20% of corn oil and 20% of rice bran oil. B50 contains 50% of diesel, 25% of corn oil and 25% of rice bran oil. We are mixing these oils with diesel and other additives in three different ratios in-order to get the maximum performance and lowest emission from a diesel engine. These samples are used as an alternative to conventional diesel in a diesel engine and the engine’s performance was evaluated. The performance of the engine is evaluated by parameters which include brake thermal efficiency, volumetric efficiency, specific fuel consumption and torque. The emission parameters are also tested which includes the emission level of CO, CO2, NOX, SOX and HC. These tests are done under different load conditions varying form no load up to 10kg. The results from the three samples (B30, B40 and B50) are compared to the conventional diesel which is being used in most conditions.

This research examines the properties of metal matrix composites (MMCs) made from aluminium 6061 T6 with boron carbide and silicon carbide. Aluminium material is a matrix metal with appealing features such as lightweight in nature, high strength and machining with ease. Stir casting is less expensive, simple and used for mass production of MMCs. By adding B4C as (2%, 4%, 6% and 8%) and SiC as constant (5%) reinforcement, the samples are fabricated. The hardness in the material tends to extend by adding the proportion of reinforcement in the metal matrix. Increasing the content of B4C and SiC particles, the MMCs have superior wear resistance.

Published: January 2023

Flow separation in an aircraft is one of the ground causes of decrease in the lift and increase in the pressure drag which eventually leads to loss of energy, vibrations in machinery and may cause structural failure of the aircraft. Many studies and research works have been carried out on delaying boundary layer separation. One of such works is the implementation of various active and passive devices on the surface of the wing. In this research work, we have used one such device called a passive dimple. By placing these dimples on the upper surface of the wing, a turbulent flow is induced which produces vortices, causing the boundary layer to stay attached to the surface of the wing to some extent and thereby increasing the stall angle of the aircraft. In this research work, we have placed outward dimples on the upper surface of the wing at various positions and ran simulations at different angle of attacks to observe the effects.

Published: January 2023

Single Expansion Ramp Nozzle (SERN) is a direct extension nozzle where the gas pressure flows from one place to other works only on one side. The SERN is a hypersonic speed demonstrator vehicle due to its advantages and operational limitations. The demonstrator vehicle is designed to attain a cruise flight at a speed of Mach 6.2. The operating limits given as constraints are the atmosphere limitations, i.e., within the lower atmosphere wherein the vehicle has to run on air-breathing scramjet engines. The project emphasizes the effect of performance parameters, namely thrust, lift and moment, due to variation in jet Mach number and jet pressure through a nozzle. The nozzle is considered separately due to the experimental limitations. The CAD model designed for the nozzle is taken. Only the vehicle's nozzle section is dissected from the whole model for the numerical simulation. The GAMBIT software is used to mesh the model and tocreate the domain space. The model is a 3D structure aligned to the 3 axis coordinate system, where the body's length is aligned along the x axis and width of the body along the z-axis. The cowl is attached to the combustion chamber exit, providing pitching stability to the vehicle. The model analysis is done in FLUENT, where the model to be solved is exported from gambit and imported to FLUENT. The cowl arrangement affects the nozzle performance and the effect of performance due to change in cowl geometry is studied. This paper presents the study of the performance parameter’s interactions with jet pressure, Mach number and cowl deflection of the nozzle

Authors: Saeed Arifa
Published: January 2023

Nexus of total factor productivity, inequality, and taxes (selected SAARC Countries) along with other control variables like corruption, consumption expenditure, capital, and labor. For short and long-run elasticities along with different estimation techniques are applied. Total factor Productivity (TFP) data of  SAARC countries were unavailable, so only Pakistan, India, Bangladesh, and Sri Lanka are estimated. Tax to GDP ratio is low, and income equality is negative as it will decrease the tax revenue, and increase in anti-corruption policies will increase tax revenue, an increase in TFP will reduce in tax revenue, increase in employment, there will be an increase in tax to GDP ratio and consumption expenditure is found negative and significant on tax The results confirm that most of the variables of the long-run elasticities are significant. All the models are robust  because there is no slope heterogeneity, heteroscedasticity, multicollinearity, and cross-section dependence among the variables.

Food safety and the high demand for food have represented worrisome problems worldwide in recent decades. It is well known that plants can accumulate metals from contaminated soil and through deposits from pollutant emissions released by contaminated sources. Cadmium, copper, zinc, and lead are poisonous elements. The accumulation of heavy metals in plants grown in polluted areas represents a major risk to human and animal health. Soil pollution with heavy metals is a global problem that has an unfavourable impact on the environment. For this study, data collected from 65 individual households located in the Copşa Mică area were used to estimate the bioaccumulation of four different heavy metals [cadmium (Cd), lead (Pb), zinc (Zn), and copper (Cu)] in onion bulbs in different scenarios, in correlation with the total metal content from the soil. The highest correlation coefficients were obtained for the regression curves established for the estimation of Cd (r = 0.648***), Zn (r = 0.592***), and Pb (r = 0.525***) in onion bulbs. In the case of copper (Cu), the linear correlation coefficient was insignificant (r = 0.088ns). The mean cadmium and lead values determined in the onion samples from the study area did not exceed the maximum stable levels for these contaminants in vegetables.

This study measures financial inclusion by using the multidimensional index approach in selected Asian countries. We used two new indices for the first time: (i) financial institution access for investigating the ease and availability of financial services; and (ii) technological innovation index for the usage of financial services with available technology. We also introduced a new dimension for the financial inclusion index by incorporating insurance and financial services. The annual balanced panel data of 25 Asian countries from 2004 to 2020 were used. Overall, the results of all three indices showed that the selected Asian countries are performing well within available resources. Israel is at the top of the financial inclusion index, whereas Cyprus and Lebanon lead the financial institution access and technological innovation indices, respectively. Contrary, Myanmar is at the bottom of all three indices. Several policy suggestions are also provided to increase the level of financial inclusion.
