Professional Biography: I obtained my master degree in Theoretical and Applied Fluid Dynamics from the School of Mathematics, University of Manchester in 2008. In the same year, I was awarded a full PhD scholarship in mechanical engineering by the School of Mechanical, Aerospace and Civil Engineering (MACE) of The University of Manchester. I am currently on my second year doctorate programme working in Plasma Actuators Development.
Research interests: Plasma actuator investigations, Surrogate modeling (Response surface and Neural networks), Commercial CFD Packages, Renewable energy, Environment and Climate change.
Project abstract
Single dielectric barrier discharge (SDBD) plasma actuator optimization has been carried out in University of Manchester. The effect of some parameters such as dielectric thickness, voltage amplitude and driven frequency was examined. Increasing the driving frequency led to an optimum frequency of operation for each actuator. It observed that increasing the voltage and dielectric thickness increased the induced velocity. This growth continues up until the presence of filamentary regime of plasma. There are many other parameters which influence the efficiency of SDBD that is going to be investigated. Other configurations of SDBD actuator, changing waveform of input signal, dielectric material and different dimension of electrodes and dielectric are amongst many factors that their influence will be examined. Investigating the possibility of further increase of induced velocity by the multiple actuators will also be considered.
