The unsteady flow field in a reversible pump-turbine is investigated during the continuous load rejection using a 3D computational fluid dynamic analysis. Numerical calculations are carried out using the detached eddy simulation (DES) turbulence model and a new approach involving automatic mesh motion. In this way. the instability of the flow field is analyzed by continuously changing... https://www.chiggate.com/philadelphia-eagles-mitchell-ness-head-coach-hoodie-sale/
