The application of water jet in removing ice from river, sea or surface of objects has many advantages, such as no mechanical strike and damage, easy control and portability. While very few investigations have been carried out. So, experimental study of deicing by means of water jet is conducted in this paper. In the experiment, the ice is naturally frozen in a rectangular mold. And the ice is struck...
In order to predict cavitation performance drop of the centrifugal pump, the RNG κ-ε turbulence model and the mass transport cavitation model are applied to simulate the cavitation flows in a centrifugal pump at different flow rates. The influence of condensation coefficient of the mass transport cavitation model on numerical simulation is analysed. According to the calculation result, the value of...
The hydraulic performances as well as the cavitation phenomena in a scaled residual heat removal pump were investigated by experimental and numerical methods, respectively. In particular, a three-dimensional numerical model of cavitation with the standard k-ε turbulence model was adopted to simulate the internal cavitating flow through the model pump, and a high quality polyhedral grid was generated...
