Research
Mathematical modelling of fluid mechanics, heat transfer, and combustion problems.
Develop numerical methods and coldes (grid generation and "Navier-Stokes" solver) that can be used to study complex steady and unsteady, multidemensional fluid flow problems that can be laminar or turbulent, reacting or nonreacting, single- or muti-phase. Current focus is on error estimation in CFD and issues on verification and validation.
Computational study of problems in aerodyamics (air foils and wings with ice accretion and shockwave/boundary-layer interactions with bleed), propulsion systems (turboject inlets, gas turbine combustors, piston and rotary engines, automotive torque converters), turbine cooling (blad-passage/endwall aerodynamics and heat transfer; internal and film cooling of turbine vanes, blades, and "edges"; conjugate heat transfer), two-phase flows (free-surface flows, objects impacting from air into water, electrodeposition of colloidal particles; particle/particle and particle/fluid interactions in particle-laden flows and atomozation and sprays), materials processing (thermal spray forming, cold spray forming), and thermoelectric power generation (heat transfer issues in TE couples, heat transfer enhancement in heat exchanger), multifunction materials (thermal-fluid issues and energy harvesting).
