Order-lifted data inversion/retrieval method of neighbor cells to implement general high-order schemes in unstructured-mesh-based finite-volume solution framework

Autor: Guo, Hao, Jiang, Peixue, Ma, Xiaofeng, Hu, Boxing, Zhu, Yinhai

This study introduces an order-lifted inversion/retrieval method for implementing high-order schemes within the framework of an unstructured-mesh-based finite-volume method. This method defines a special representation called the data order-lifted in

Development of low-dissipative projection method framework integrating various high-order time integration schemes using OpenFOAM

Autor: Guo, Hao, Jiang, Peixue, Zhu, Yinhai

A low-dissipative solution framework integrating various types of high-order time scheme is proposed and implemented based on the open-source C++ library OpenFOAM. This framework aims to introduce different categories of low-dissipative time integrat

Publikováno v: J. Fluid Mech. 970 (2023): A2

In this article, we propose a divergence-free method for the generation of inhomogeneous and anisotropic turbulence. Based on the idea of correlation reconstruction, the method uses the Cholesky decomposition matrix to re-establish the turbulence cor
