Flow Control: From Inception to Application

Michael (Miki) Amitay
Mechanical, Aerospace and Nuclear Engineering Department
Rensselaer Polytechnic Institute (RPI)

Flow control has emerged as an enabling technology to improve vehicles’ performance.  It involves passive and active devices to affect a beneficial change in wall-bounded or free-shear flows.  The presentation will provide and demonstrate a few ideas to control flows and the route(s) to application. The talk will be divided into three major parts:

  1. Current and future activities in the Center for Flow Physics and Control at RPI.
  2. Piezoelectric-based actuators, including synthetic jets, dynamic low aspect ratio, surface mounted pins, and Piezoelectrically Driven Oscillating Surface (PDOS) actuators and their interaction with different cross flows.  This will include a flow over a flat plat, laminar-turbulent transition control, and separation control over flapped airfoils.
  3. Application: performance enhancement of a vertical tail of a commercial airplane using distributed finite span Synthetic Jet actuators – from small-scale wind tunnel model(s) to flight.

The talk will be given in English
