Numerical Simulation of Cavitation in Mixed Flow Pump
The purpose of this study is to investigate the performance and three-dimensional behavior of the flow in a mixed flow pump and the way cavitation phenomenon is affected by different parameters such as fluid temperature, pump speed and flow rate. Computational fluid dynamic software FLUENT 6.3 was utilized to simulate the whole flow field of the pump. RNG k-ε model combined with standard wall f...
متن کاملNumerical Simulation of Air-Water Bubbly Flow in Axial Flow Pump Impeller
In this paper, the lift-law method was applied to design the axial flow pump. Based on Reynolds time-averaged N-S equations and standard k turbulent model, three-dimensional air-water bubbly flow in an axial flow pump impeller was simulated. Under the condition of bubble void fraction of 5%, pressure and void fraction distributions were respectively obtained, movement of bubbles in the impeller...
متن کاملNumerical Simulation of Unsteady Flow in a Scroll Compressor
A new template simulation tool is developed for scroll compressors/expanders. This scroll template generates a high quality multi-block structured mesh from the outlines of stationary and orbiting rotors, which are inputs from a user. The mesh movement is also automatically calculated to account for every position of the orbiting rotor, maintaining good grid quality and smooth movement througho...
متن کاملNumerical Simulation of Unsteady Flow in Resonance Tube
Computational results are presented for the unsteady flow in a powered Hartmann resonance tube. The results were obtained using the WIND code for the two dimensional viscous flow in a five-block solution domain that includes the CD nozzle supplying the jet to the closed end tube within the ambient surrounding. The computed results are presented for the unsteady flow mechanisms involved in the r...
متن کاملnumerical simulation of air-water flow in bottom outlet
flow regime in dam's bottom outlet is divided in pressurized flow and free surface flow by the gate located for discharge control. down stream tunnel involves high velocity multi component air –water flow studied by mathematical model. in this research work, we used finite volume mixture two phase flow model. because of high reynolds number, standard two equations k-e turbulence model was ...
