<p><P>PROBLEM TO BE SOLVED: To provide a thermal fluid simulation method for shortening time for simulation calculation without deteriorating accuracy. <P>SOLUTION: A calculation condition used for simulation calculation is inputted (S1), a flow field and a temperature field in an initial state are simulation-calculated using the input calculation condition (S2), a velocity (surface fluid velocity) of a fluid contacting with the surface of a mobile object is calculated and set as a boundary condition (S3), a corrected heat conductivity is calculated based on the moving direction and moving speed of the mobile object (S4), the flow field and the temperature field are simulation-calculated using the surface fluid velocity and the corrected heat conductivity (S5), whether the balance calculation between the flow field and the temperature field reaches convergence or not (S6), and when it is not converged, the procedures S5 to S6 are repeated until the balance calculation reaches convergence. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
