Comparison of Local Computational Approaches for Unsteady Viscous Incompressible Flows

Nobuyuki Satofuka; Koji Morinishi; Itaru Tanno; Tomohisa Hashimoto; Takahiro Yasuda; Yoshihiro Tanaka

Numerical simulations of 2D decaying homogeneous isotropic turbulence are presented using three local computational approaches, ACM, KRLNS equations and LBM, in order to investigate accuracy, efficiency and the capability to capture the correct transient behavior of the incompressible flows and the results are compared with the solutions obtained by the Pseudo-Spectral Method (PSM), which is the standard method for this problem. Parallel computations are carried out on a GPU by using the CUDA library provided by the NVIDIA and the speedup is investigated. It is found that all three methods can capture the transient flow fields and LBM is the most accurate and efficient approach for this kind of unsteady incompressible flow.
