Welcome to my ePortfolio.
I am a research associate at the centre for Scientific Computing / School of Engineering at Warwick University. My research focus is on turbulent vortex rings. I run numerical simulations in order to look closely at turbulent vortex ring structures that occur in the flow. I have a BSc in Mechanical Engineering and an MSc in Sustainable Energy and Environment. I am also interested in teaching. I have tried to make my ePortfolio as useful as possible for the visitor.Please feel free to contact me regarding any questions in the field of computational fluid dynamics (CFD).
If you are interested in cooperation, please do not hesitate to connect with me. This website will not be updated any more therefore for researchers who are intrested to follow up my latest research updates they are advise to go to the following link: http://cfd2012.com/index.html
About My Research:
What best describes my research vortex rings is the bubble rings blown by dolphins. The first question that comes in mind, whats the use of studying such a phenomena? The vortex ring phenomena has lots of applications, it is generated by giving a stationary mass of air a high amount of momentum at a short period of time, this happens in engines, in pumps, in combustion chambers ......etc. WIth this kind of action , if the researcher can capture this pattern using high frame rate capture cameras a through understanding of fluid mass transfer dynamics can be achieved. At first when the mass of gas is given its initial blow it stays intact , with the progress of time it starts fluctuating with the ring getting lots of curvature patterns on its surface until it gets to the point of break down. Depending on application comes the stage of concern for the researcher.

Spray modelling, this is a test trial of water spraying using a novel spray design. Here is the latest tutorial for spray modelling enjoy Spray_modelling . Send me an email to request the the required geometry for the spray tutorial.
Images of Some Conducted Simulations:
Running a simulation on a space shuttle model during the stage of re-entry.
Formual BMW F1 Trial: Unfortunately i couldn’t get a finer mesh which lead to having the irregular mesh visible, the limitation was a license and hardware issue. A prespective View:
While working in industry you will be assigned problems to overcome, after completing your modeling stage and getting the product to do its main purpose , the next step is to validate that its shape and its parts work at their best, what is meant by that is dose the shape of the product produce more drag for the user such as a bikers helmet, or for adding car mirrors that have the least drag for the car design. The other issue for internal flows of a product such as ventilation air currents in a gear box or an electrical motor for a pump and the list will just go on and on. This is where star CCM comes is the need to model flows inside or outside a product so that it performs its best performance at the least price. The researcher has to import the model into star CCM and then see what flow patterns are formed due to different input parameters. Then comes the analysis part after the simulation is run due to lots of data is generated
