The potential and laminar flows over a wavy surface have been studied in this pa-per.For the potential flow,theoretical analysis and FA numerical computation are adopted re-spectively.The results of these two methods agree well with each other.For the laminar flow,the numerical analysis is mainly carried out.In computation,the body-fitted coordinate trans-formation and more perfect FA method are used.The achievements show that the difference ofthe wall pressure distribution between the potential and laminar flows is not significant when theratio of wave height to wave length a/λ is smaller,or vice versa,and there are separate regionsin the laminar flow field.
Potential and laminar flows over a wavy surface were studied in this paper. For the potential flow, theoretical analysis and FA numerical computation were adopted respectively. In the computation of the laminar flow, the body-fitted coordinate transformation were used. The results of two methods agree very well. The results show that the difference of the wall pressure distribution between potential and laminar flows is not significant, when the ratio of wave height to wave length is smaller and there are separated regions in the laminar flow field.
