Computational Studies of High-Speed Shear Flows

Shear flows occur in many fluid mechanics applications ranging from incompressible subsonic flows to compressible hypersonic flows, such as boundary layer flows developing overground, submersible or airborne vehicles, jet flows emitted by aircraft engines or rocket nozzles, or wakes generated by blunt objects moving through air or water. In this talk, our previous and current efforts aimed at computationally analyzing and controlling various shear flows, in an attempt to reduce the frictional drag force of alter the heat transfer, are presented and discussed. 初级数学 model is represented by the Navier-Stokesequations, describing the motion of a non-Newtonian viscous fluid, which are discretized and solved in the framework of large eddy simulations or non linear boundary region equations. The talk will cover computational fluid dynamics applications in areas such as high-speed jet flows, boundary layers and free mixing layers, as well as the application of a robust nonlinear optimal control strategy targeting the reduction of the frictional drag in high-speed boundary layers.
