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.
