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.
· Developed solution-adaptive method for FCT solver.
· Developed K-ε model used for simulation of fast multiphase turbulent reactive flows.
· Developed front-tracking method using Level-Set method on unstructured grid.
· Developed real-gas, condensed-phase, and particle equations of state for reactive multiphase flows.
· Developed code to generate unstructured, structured, or hybrid grids about airfoils.
Developed TVD multi-block multi-grid Euler code and
modelled 2-D wind-tunnel wall interface;
stimulated further research into improved correction techniques for transonic conditions.
· Modified 3-D Navier-Stokes code, ARC3D, and simulated 3-D tunnel interference.
Generated innovative multi-block grid about deHavilland Dash-8 aeroplane using GRIDGEN;
reduced memory usage by 45% and improved grid quality at aeroplane surfaces.
Evaluated commercial unstructured 3-D Navier-Stokes codes for CF-18 stores separation;
chose 2-D and 3-D test cases and collaborated in subsequent validation of RAMPANT.
· Tested and improved 3-D Euler code and simulated 3-D transonic flows about CF-18 wing.
· Developed vectorized Euler code on CRAY to simulate flows in hypersonic impulse tunnel.
· Invented a dynamic solution-adaptive finite-difference technique to earn my Ph.D.
· Developed wave-tracing code to simulate explosive compression of graphite powder.
for Infrared Intrusion Detector #1095302 Canadian Patent, 10 Feb. 1981,
D. Hawken and Z.W. Turleg, used in intruder alarms manufactured by Dicon Systems.
· Developed a Monte-Carlo lens-design program and used it for optical smoke-alarm design.
