Spectral Dierence Solution of Two-dimensional Unsteady Compressible Micropolar Equations on Moving and Deformable Grids

The Micropolar uid theory augments the laws of classical continuum mechanics by incorporating the rotational e ects of uid molecules on the continuum. The theory of Micropolar uids has shown promise for predicting uid behavior at microscale. This paper presents the development of a 2D high-order solver with unstructured spectral difference method for unsteady compressible Micropolar equations on moving and deformable grids. This work is an extension of previous work published by Liang et al and Chen et al. The dynamic grid technique is based on a blended-function technique which is similar to Persson et al, Ou et al and Yu et al.
