Parametric Study of a Solar Heat Driven Silica Gel–Water Paired Adsorption Chiller
Abstract: Heat driven sorption based cooling systems are gaining interest as they are environmentally friendly and have the potential to save precious fossil fuel resources. Low grade thermal sources like solar or waste heat can run a silica gel-water paired adsorption chiller to generate chilled water below 10°C. However, the performance of the adsorption chillers is poor when compared to vapour absorption or vapour compression based cooling systems. An effort has …

Finite Difference Analysis of Plane Couette Flow using MATLAB
Abstract: Internal flow is a flow for which the fluid is confined by a surface. Hence, the boundary layer is unable to develop without eventually being constrained. An internal flow is constrained by the bounding walls, and the viscous effects will grow and meet and permeate the entire flow. Some examples of internal flows are: flow between two parallel horizontal plates, Couette flow, plane Poiseuille flow, flow through pipes, etc. In …

Analysis of Vehciles Body Automobile to Study Drag Characteristics
Abstract: Today’s most hot selling cars on the market are sedan. Thus, people have more expectations at the semidrange budget cars. These expectations could be achieved by increasing the car performance such asfuel economy, aesthetics and speed and reducing the drag force which is applied on it. Fuel economyand speed could be easily achieved by decreasing the drag coefficient and drag forces. Drag plays oneof the major roles in fuel economy …

Using digital holographic interferometry to monitor symmetrical temperature fields in liquids and an interference technique for simultaneous heat and mass transfer
Abstract: In this work, we offer a technique for off-axis digital holographic interferometry to measure dynamic temperature change quantitatively in real-time and visualise volumetric temperature fields formed by a 2D axial-symmetric heated fluid from a pulsatile jet in a water tank. For the experimental examination, a portable Mach-Zehnder interferometer was constructed. The pulsatile jet was supplied with hotter water and submerged in a tank of water.
