Multi-fidelity modeling framework for wind energy applications based on ALM-VMS formulation for stratified flows
In this seminar a high-fidelity numerical framework for wind energy applications developed by the CFSMgroup at the University of Calgary (https://www.cfsmgroup.com/) will be discussed. The framework is based on the variational multiscale (VMS) formulation for fluid mechanics and uses the incompressible Navier-Stokes equations along with a transport equation for temperature. The formulation uses either linear finite-elements or quadratic NURBS for spatial discretization. The formulation is further coupled with the Actuator Line Method (ALM) to reduce the computational cost when modeling wind turbine rotors. The stability and accuracy of the numerical formulation near the wall is enhanced through the weak imposition of the boundary conditions, which shares similarities with classical wall modeling approach. The accuracy and robustness of the framework will be demonstrated on various examples, including but not limited to multiple wind turbines simulation under the stable atmospheric boundary layer flow, wind farm simulation, flow over the complex terrains, and other examples.
