Analysis of Innovative Vapor Compression and Thermal Energy Storage Systems Using Alternative Refrigerants
Morad, Bahaa (2016-12)This research presents detailed analyses of innovative single and two stages vapor compression refrigeration cycles (VCRCs) as well as a cold thermal energy system (CTES) for residential and commercial cooling applications. ... -
Control of Flow Past an Airfoil Section Using Rotating Cylinders
Nazari, Argin (2015-02)The flow past a NACA 0024 airfoil with a leading edge rotating cylinder is simulated numerically using the ANSYS CFX software. To delay the boundary layer separation from the airfoil surface, different configurations for ... -
Evaluation of a Cold Thermal Energy Storage System Using Alternative Refrigerants
Alshaibani, Salah Ali (2016-05)This study provides a detailed comparison study between clathrate hydrate of R134a and R404a refrigerants in a direct contact thermal energy storage system. Numerous closed loop cycles using hydrate of each refrigerant ... -
An Experimental Investigation of R134a Clathrates with Liquid Additives
Gulzar, Hafiz M. Ahmad (2016-09)Thermal energy storage (TES) using phase change materials is one of the most effective solutions for energy conservation. The selection of a phase changing material (PCM) with different liquid additives could improve the ... -
Prediction of Turbulence Statistics in a Model Dump Combustor Using Artificial Neural Networks
AlSharif, Amin Moh'd (2011-05)The flowfield characteristics downstream of an axisymmetric suddenexpansion dump combustor model are important to designers of gas turbines and liquid-fuel ramjets ducted rockets. Many experimental techniques such as Laser ... -
Suppression of Rotating Stall by Throttle Rings Control in Vaneless Diffusers of Centrifugal Compressors
Mohammed, Dhafar (2006-04)Centrifugal compressor systems are widely used in many industrial applications. However, the operation of such systems is limited at low-mass flow rates by fluid flow instabilities. These instabilities lead the compressor ... -
Suppression of Unstable Flow by Using Rough Surfaces at Small Mass Flow Rates in a Radial Diffuser
Salem, Hayder (2006-08)The operation of centrifugal compressor systems is limited at low-mass flow rates by fluid flow instabilities leading to rotating stall or surge. These instabilities limit the flow range in which the compressor can operate. ...
