EXPERIMENTAL STUDY ONFLUIDIZED BED USING AN ENHANCEDVERTICAL EJECTOR WITH HORIZONTAL JETS CONFIGURATION

Experimental Study of Parallel Jets Scouring, considering the effect of jets distance on erosion rate

The scouring process at downstream of the hydraulic structures is a complex phenomenon and many parameters affecting its amount. Failure to control this phenomenon causes damages to the dam and its associated hydraulic structures. In this research, the scouring caused by the combination of jets outlet from a gated spillway was investigated experimentally and the combination of jets adjacent to ...

Experimental Study on the Performance of Dual-Evaporator Refrigeration System with an Ejector

Experimental investigation on the performance of dual-evaporator refrigeration system with an ejector has been carried out In this study, HFC-134a is chosen as a working fluid. Test setup is composed of compressor, condenser, expansion valves, two evaporators, and ejector which is installed between two evaporators. The condenser and two evaporators are made as concentric counter-flow type heat ...

An experimental study of evaporating small diameter jets

The behavior of evaporating small diameter jets in a low-pressure environment is studied experimentally. Charged coupled device (CCD) cameras connected to a computerized data logging system are employed for high-speed imaging. Experiments at different jet velocities and environmental pressures have been performed with pure ether and ethanol, and also the mixtures of the two. Complex instability...

Simulation of local scour caused by submerged horizontal jets with Flow-3D numerical model

One of the most concerning issues for researchers is to predict the shape and dimensions of the scour pit nearhydraulic structures such as the base of bridges, weirs, valves and stilling basins due to both financial and humanhazards induced by destruction of the structure. As the scour issue has its own complexity in relation to themultiplicity of effecting factors on it, in this study therefor...
