| Abstract: |
| A grids algorithm for two dimensional domains enclosed by four unregular and complicated lines was derived for the combustor of a small turbofan engine.The mathod was put into use successfully in application to CFD of the annular combustor.It proved that the algorithm has the advantages of simplicity,efficiency and accuracy.It was useful in the numerical simulation for the combustor of turbojet engines. |
