Development of a multiblock pressure‐based algorithm using mixed interpolation for turbulent flows

A new multiblock pressure-based finite element algorithm has been developed. This methodology implements a novel quadratic interpolation for the elemental pressure while using a bilinear interpolation for the velocity. Details of the algorithm and its multiblock foundation are provided along with a complete description of the implementation of the RNG-based k-e model. The results presented clearly demonstrate the validity and accuracy of this new approach for complex flow problems such as diffusers.
