You're invited to a seminar with Dr. Kewei Xu, a postdoctoral researcher at Chalmers University of Technology in Sweden, titled "Numerical Investigation of Active Flow Control in Various Applications for Performance Improvements and Flow Physics Study."

Abstract: Nowadays, as traditional aerodynamic design reaches the performance plateau, novel active flow control (AFC) methods have become increasingly attractive and are extensively studied for diverse purposes, e.g., drag reduction, lift enhancement, stall margin enlargement, etc. The goal of active flow control is to achieve high control effectiveness while minimizing energy expenditure. In other words, the net benefit is what matters. This seminar will discuss how net benefits are achieved using active flow control in various applications, including empennages side-force enhancement, wind turbine power improvement, S-inlet distortion elimination, and ship drag reduction. The discussion will also involve the underlying flow control mechanisms, which are based on the analysis of the turbulent wall jet momentum equations and the analysis of turbulent kinetic energy in wakes. Building on the prior research, the seminar will outline future efforts in active flow control and machine-learning-driven research to address emerging challenges in sustainability, energy, and air mobility.

Biography: Dr. Kewei Xu is a postdoc researcher at Chalmers University of Technology, Sweden. Research interests include CFD, active flow control, aircraft aerodynamics, turbomachinery, machine learning, wind turbines, and bluff body aerodynamics.
