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.
