HEAT FLUX MEASUREMENT AND NUMERICAL SIMULATION OF FLOWFIELD ON LENS DOUBLE CONE GEOMETRY.

This paper presents the numerical simulations of flow field over a typical 25°-55° sharp tipped axisymmetric double cone at different flow conditions using ANSYS Fluent. Detailed surface heat flux and pressure measurements over the model have been made with well-defined boundary conditions. Flow features such as shock interactions, location of the sonic line are captured very well in the present simulations. The simulation distribution shows excellent match with the experimental results taken from the database of Calspan University at Buffalo Research Centre (CUBRC).
