On the Introduction of the Irreversibility in a DBD Plasma Based Channel Flow: A Study on Entropy Generation Rate

چکیده
In the present research, a brief study on the impact of DBD (Dielectric Barrier Discharge) plasma actuator on the entropy generation rate in a channel flow is presented. The work has been continued in the certain inlet Reynolds number of about 670. Moreover, the problem is assumed to be a two dimensional DBD plasma based channel flow with the assumption of the incompressible flow. Since, the distribution of entropy generation rate is governed by a contribution of temperature and velocity gradients, and besides, the distribution of DBD plasma body force is highly depended on the channel width and other parameters of the actuator configuration, it would be difficult to include the whole engaged effects together for pursuing the study of entropy generation rate in a plasma based channel flow. So the present work aims to provide an over view on this problem. Therefore, for a certain channel geometry and inlet Reynolds number and different DBD plasma configurations, entropy generation rate and Bejan number is studied.
