Assesment of a Kinetic Eddy Simulation Turbulence Model for 3D Unsteady Transonic Flows

Modeling Dynamic Stall of SC-1095 Airfoil at High Mach Number

“…KES is a method of attempting to capture benefits of LES inside of a RANS code, and researchers have found that it produces good results for the type of 2-D dynamic stall flows considered in this work. [24] OVERFLOW is a time marching implicit Navier-Stokes code that has been developed for 3-D but is easily applicable to 2-D problems. It utilizes overset or Chimera grids to allow for modeling various flow phenomena as efficiently as possible.…”

However, at the higher Mach numbers pitching moment is sometimes overpredicted at high angle of attack.…”
