Role of corner flow separation in unsteady dynamics of hypersonic flow over a double wedge geometry
Gaurav Kumar, Ashoke De
This study investigates the origin and sustenance of self induced oscillations of shock structures in a hypersonic flow over a double wedge configuration. Previously, various resea…
Prediction of Separation Induced Transition on Thick Airfoil Using Nonlinear URANS Based Turbulence Model
Alok Mishra, Gaurav Kumar, Ashoke De
Most of the turbulence models in practice are based on the assumption of a linear relation between Reynolds stresses and mean flow strain rates which generally provides a good appr…
Investigation of flow structures in a turbulent separating flow using hybrid RANS-LES model
Gaurav Kumar, Ashoke De, Harish Gopalan
Hybrid Reynolds-averaged Navier Stokes large eddy simulation (RANS LES) methods have become popular for simulation of massively separated flows at high Reynolds numbers due to thei…
Investigation of asymmetrically pitching airfoil at high reduced frequency
Mitesh Thakor, Gaurav Kumar, Debopam Das +1
The expanding application in Micro-Air Vehicles has encouraged many researchers to understand the unsteady flow around a flapping foil at a low Reynolds number. We numerically inve…
