摘要：
A integrated method solving fluid and solid simultaneously is used to deal with complicated flow and solid temperature field coupling problems. A simple but effective approach is proposed to overcome stiffness in two-equation turbulence models. Related theory is provided. With this method, efficiency in multigrids and LUSGS implicit temporal stepping method is increased remarkably. © 2009 Chinese Nuclear Society.
