Research Background
Dr. Chang Wei Shyang is an accomplished senior lecturer and lead researcher at the School of Aerospace Engineering, Universiti Sains Malaysia. He completed both his undergraduate Bachelor of Aerospace Engineering (Honours) degree and his specialized Doctoral PhD path inside Universiti Sains Malaysia. His underlying operational research background is strictly rooted in Numerical modelling frameworks, focusing significantly on structural Energy-stable Residual Distribution Methods developed primarily to evaluate and solve complex Shallow Water Equations with variations across bottom topographic boundaries.
Current Research Projects
- Source term discretisation on Energy-stable Residual Distribution Method
- Hydrofoil design parameter optimization and analysis
- Aerodynamic performance validation checks for vertical-axis active flow structures
