Abstract

Abstract

In order to achieve large-scale numerical simulation of chemical oxygen-iodine laser(COIL) flow, a three-dimensional COIL multiblock parallel simulation code is developed. In this code, the basic equations and numerical algorithms of VICON code are adopted, and the patch-based data structure and the parallel algorithm for multiblock structured mesh of JASMIN infrastructure are used. The simulation results demonstrate the accuracy and scalability of the parallel simulation code. In the simulation example with 4.5 million meshes in 2048 CPU cores, the speedup of the code is higher than 420.
