Abstract With historical roots linked to life sciences, species diffusion has inspired dynamic models for infectious disease spreading. However, drawbacks have been raised towards the inclusion of people’s displacement effects, whose ordered motion might refer to species convection within transport phenomena perspective. By transcending usual geometric role of spatial coordinates, the present work proposes a […]

Abstract Ventilated discs have gained significant attraction for automobile disc brake due to enhanced thermal performance, but the optimal choice needs careful analysis of thermal and structural behaviors. Following the previous studies on solid and straight ventilated discs, the present study considers discs with three new ventilation patterns namely curved vents, curved vents with holes […]

Abstract Distributed energy, also known as district or decentralized energy, is generated and stored by a variety of small, grid-connected devices referred to as distributed energy resources, or distributed energy resource systems. The Distributed Generation (DG) systems can increase energy system reliability, reduce peak power requirements, and improve energy infrastructure resilience. In this study, a […]

Abstract Due to the extreme miniaturization of devices, enhancing the heat transfer rate has been a challenging task in the electronic industry. Several researchers have conducted experiments to gain maximum heat transfer rate in small spaces. So, the current study focuses mainly on improving the thermal dissipation characteristics from the surface by creating grooves across […]

Abstract There is growing interest to study the effect of blending various oxygenated additives with diesel or biodiesel fuel on engine performance and emission characteristics. This study aims to analyze the performance and exhaust emission of a four-stroke, four-cylinder diesel engine fueled with biodiesel-ethanol-diesel. Biodiesel was first produced from crude Jatropha oil, and then it […]

Abstract This paper presents the thermodynamic performance analysis of an existing combined cycle power plant to be retrofitted with a waste heat driven aqua lithium bromide absorption refrigerator for cooling the inlet air streams to the compressor and air-cooled steam condenser. The power plant is located in the hot and humid tropical region of Nigeria, […]

Abstract This study analyzes the performance of biodiesel blended with diesel for fueling a diesel engine. Biodiesel was produced from crude Jatropha oil with a high acid value (15.99 mgKOH/g) by using a two-step alkaline (base) catalyst process. The engine performance and emissions characteristics of Jatropha biodiesel blends of B5, B10 and B20 were studied […]

Abstract An experimental and numerical investigation of unconfined liquefied petroleum gas (LPG) fueled inverse diffusion flame (IDF) is presented. The effect of air-fuel velocity ratio on the appearance of the LPG IDF are investigated. A fixed air jet velocity of Va = 11.31 m/s is chosen for the analysis, while the fuel jet velocity is […]

Abstract This paper presents a numerical analysis of magnetohydrodynamic (MHD) boundary layer flow of Jeffrey fluid over a porous unsteady shrinking sheet considering the suction parameter. The governing nonlinear partial differential equations are converted into ordinary differential equations by using a similarity approach. Numerical solutions of the nonlinear ordinary differential equations are found by using […]
