Abstract :
A new active way to control laminar stability through feedback control strategy is presented in this paper. By applying the expansion method, the small perturbation parameter, which is related to uniform boundary heat flux, is well separated out from the problem we studied. As a result, the heat flux independent coefficients, which reflect the temperature dependent viscosity effects, can be obtained. It is shown that this feedback laminar flow control strategy can considerably dominate the development of fluctuations provided that the phase of heating or cooling and the control position are properly chosen.
