ABSTRACT
ABSTRACT:
Why study mixing? Fluid mixing is often encountered in engineering applications and it is carried out in order to achieve good performance in some processes like the mixing of air and fuel in combustion engines. Persistent patterns in chaotic fluid mixing have been observed in experiments and numeric simulations but could not described mathematically. With the help of Floquet theory, we will present an answer to this open problem. Why flow control? In engineering applications we often need to control a flow to behave in a desirable way. For instance, we need to design a control to stabilize a laminar flow which is preferred in engineering. In this talk we also show boundary feedback controls designed for 2D channel flow.
Refreshments will be served at 3:00 p.m. in Clearihue D-267.
Dr. Liu is a candidate for the Applied position in the Department.
