Fluid dynamics

Various developments in the field of fluid dynamics are discussed. An active area of research in the US has been the application of hybrid Reynolds-averaged Navier-Stokes (RANS) large-eddy simulation (LES) methods to aerodynamic flows. The researchers at the Hong Kong University of Science and Technology are working on the Boltzmann equations, while simulation of nonequilibrium flows are the subject of the researchers at Old Dominian University. The computational plasma program at the University of Florida, in collaboration with the Computational Sciences Center of Excellence at the Air Force Research Laboratory (AFRL) has successfully predicted plasma-based stall control for NACA airfoils and turbine blades at high angle of attack. Rutgers University has reported significant progress in the use of microwave energy deposition, expanding the possible flow control in high-speed flows. Researchers at the University of Illinois Champaign-Urbana are investigating laser and microwave energy deposition methodologies and actuators.
