Object and purpose of research. Pressure pulsations induced by cavitating blades substantially contribute to flowinduced loads amplify structural vibration. These depend on oscillation the volume cavities over blades. Prediction them usually involves model tests there are three kinds scale effects influencing cavity volumes. The first one is associated with non-uniform inflows. second combined ...

The characteristic of large-scale multiobjective optimization problems (LSMOPs) is optimizing multiple conflicting objectives while considering thousands decision variables at the same time. An efficient algorithm for LSMOPs should have ability to search a large space and find global optimum in objective space. Maintaining diversity population one effective ways locate Pareto optimal set In thi...
