[Grid About Airfoil in Wind Tunnel (14K)]

[Contours of Constant Pressure in Wind Tunnel (6K)]

 

Welcome to the my Home Page. I have a background in physics, fluid dynamics, and software design. Over the years, I have developed engineering expertise in numerical analysis, flow simulation, data plotting, visualization, and software design. I worked at Martec Ltd from October 1996 until June 2005 when my employment was terminated owing to lack of work in my area. I worked at the National Research Council of Canada before that. Some of my more recent work on the Martec IFSAS and Chinook codes can be viewed by clicking on the PowerPoint presentation below.

I have also produced software on my own. You may download sample programs. You can reach me by e-mail at djhawken@telusplanet.net.
