A Preliminary Study on Application of High Order Scheme in Two-Fluid Model

The high order schemes based on Godunov method are applied to the numerical method of two-fluid model,and a numerical benchmark verification is carried out.The computation results of upwind,MUSCL,ENO and Ultra-Bee are compared and analyzed.The results show that the high order schemes are better than the upwind scheme.ENO is slightly better than MUSCL,however MUSCL is simpler than ENO,and the computation cost of MUSCL is smaller than that of ENO.Ultra-Bee shows a good ability to capture the discontinuity region,but in the continuity region the mesh number should be large enough.
