Summary on Grant Application Form
The research is directed towards the development and testing of efficient algorithm for the solution of viscous flows over helicopter rotors. The applications envisaged involve civil and military vehicles. The methodology planned involves numerical solution of the unsteady Navier-Stokes equations with simple turbulence modelling. It will initially be limited to 2D with a view to extend to 3D. High resolution scheme will be used for spatial discretisation for an accurate prediction of shock waves and shear layers including wakes. Newton-like method will be used with efficient linear solvers for fast convergence. This fully implicit approach, developed by the proposers for steady flow problems, has considerable potential for dealing with unsteady Viscous flows. The application will be directed towards the viscous dominated compressible flow phenomena associated with helicopter rotors of dynamic stall and unsteady transonic shock induced separation. The numerical simulation will be validated against fight and wind tunnel data available from DRA and WHL.
