OpenFOAM Analysis over a Flat Plate Using Plasma Actuation

Abstract

The boundary layer flow control is very important for an aerospace application. The plasma actuators are promising technology in flow control for future and the study of the plasma actuator is very important. The current work focused on the boundary layer flow control using the plasma actuators in OpenFOAM solver. The aim of the current research is to study the flow over a flat plate analysis with reduced order modelling physics using OpenFOAM. Recently, OpenFOAM gained a lot of importance to solve the numerical problems especially, in computational fluid mechanics but users are very less due its complexity. An OpenFOAM own solvers were created and tested for the plasma based reduced modelling. A flat plate without plasma actuation has been benchmarked with the Blasius analytical solution. The flow over a flat plate with plasma actuation has been analysed using reduced order modelling. From the results, it was found that flat plate with plasma actuation showed the 125 percent induced velocity improvement compared to a flat plate without plasma actuation. Hence, the plasma actuation is promising for a flow control in real world applications.
