Laminar flow past a sinusoidal cavity

The dynamic and thermal properties of a laminar flow past a sinusoidal cavity are studied. Velocity and temperature fields inside and above the cavity are numerically determined from the viscous flow equations. Results are compared with the experimental data obtained with a model placed in an incompressible and uniform flow. The good agreement with the dynamic field configuration allows the extension of these calculations to other sinusoidal wall geometries, to other main flow velocities and to cases with suction at the wall. Examples of streamlines and isotherms are given for these various situations. (Author)
