Implementation and Utilization of Inverse Design Method for Static Pressurize in Cascade

Todays, beside the continuously increasing scientific coverage of CAE1, it is widely spread in all fields of the industry. The basic reason of this is that significant cost, capacity and time can be saved by the simulation driven product development. The CFD2 is a part of the CAE, and its effectiveness can be increased more by optimization algorithms. One of these technologies is the inverse design method, in which a predefined, in specific sense so called optimal flow condition has been imposed to recover the geometry belongs to that state. An inverse design method, developed at BME3 Department of Aeronautics, Naval Architecture and Railway Vehicles, has been used in the present work for investigating the way of how the static pressurise and mass flow rate can be maximised in a cascade on such a way that the flow on the suction side of the profile to be close, but certain safe distance far from the separation. The effect of the blade pitch is also included in the present investigation.
