Abstract

A pitching airfoil problem is addressed in this paper to assess the use of a non-iterative time-advancement (NITA) scheme with dynamic mesh method, and also to estimate possible CPU time savings. Simulations have shown that using a combination of dynamic mesh and NITA scheme can efficiently predict dynamic loads with quality results similar to those obtained by iterative time-advancement scheme and sliding mesh method, but merely consuming half of CPU time of the latter approach. This study also confirms the validity of an in-house developed user-defined function integrated in a RANS CFD solver and demonstrates the efficiency and the accuracy of NITA scheme.
