The Effect of Sonication Time on Alumina Nanofluids with Paradoxical Behavior
Abstract: Nanofluids can be considered to be the next-generation heat transfer fluids as they offer exciting new possibilities to enhance heat transfer performance compared to pure liquids. Heat transfer enhancement using nanofluids have been reported in literature pertinent to thermal conductivity under the static conditions, convective heat transfer and phase change heat transfer. Except for the studies from the first category where the nanofluids exhibited much higher thermal conductivities than those …

Dynamic Simulation of Load-Responsive Vapor Compression Refrigeration Systems
Abstract: Because of their dependable operation and effectiveness, vapor compression refrigeration systems, or vapor compression refrigeration (VCRS), have become popular in commercial, industrial, and residential settings. However, under different thermal loads, classic vapor compression refrigeration (VCR) systems may perform less well in that they are usually built for steady-state conditions and run at consistent speeds. In order to improve a load-responsive VCR system’s flexibility, energy efficiency, and response to changing cooling …

Review on Main Equations for Measuring Spray Properties in Centrifugal Injectors
Abstract: The method of fuel injection has a significant effect on the stability and proper mixing of fuel and oxidizer, which is done by the injector. In other words, the injector is a device that converts fluid into droplets. The faster and better the particle crushing rate, the faster the fluid particles will evaporate, resulting in higher thermal efficiency and higher thrust force. Therefore, how to inject fuel into the combustion …
