Turbulence Structures of Flow Over a Two-Dimensional Hill-Shaped Model Available to Purchase

This study brings into focus the turbulent boundary layer flow over a two-dimensional hill with sinusoidally curved slope, which has both of convex and concave surfaces. In the regions over these two types of surfaces, it is well known that turbulence is deformed and much influenced due to velocity acceleration and deceleration. DNS has been applied to simulate the development, deformation and downstream recovery of the turbulent boundary layer flow. The momentum thickness Reynolds number of is equal to 973. Detailed information regarding streamwise changes of turbulence intensity, turbulent shear stress and kinetic energy, etc. are provided in data base manner. We hope to shed some lights on turbulence modeling for complex flows with the DNS data base of turbulence structures over the hill model.
