Our research laboratory specializes in the numerical simulation of plasma & reactive flows such as those used in aerodynamic flow control, in plasma-assisted combustion, in plasma-based fuel reforming, as well as in plasma medicine. The plasma technologies here considered can improve the performance of aircraft either through Dielectric Barrier Discharge (DBD) actuators to increase the critical angle of attack...

CFDWARP is a in-house-developed C code that totals more than 100,000 lines and that is specifically tailored to simulate efficiently plasma and reactive flows. CFDWARP is advantaged over other codes in that it integrates in coupled form the electron and ion transport equations along with the “bulk flow” transport equations using aerodynamic-scale integration steplengths....

“Introduction to CFD” is a 3rd/4th year undergraduate course giving a brief introduction to Computational Fluid Dynamics (CFD). The focus is on the simulation of compressible flows in aerodynamics. We'll see how to recast the fluid equations in generalized curvilinear coordinates, how to measure numerical error using Richardson extrapolation, and how to craft some high resolution and high order flux...

This is a third year undergraduate course about heat transfer phenomena. The course covers radiation, conduction in solids (steady and unsteady), external convection, viscous heating, internal convection, natural convection, and phase change. Example problems include the cooling of journal bearings, electricity cables, and the design of fins, hot wire anemometers, and hypersonic aircraft structural cooling...

Convective Heat Transfer is a graduate course focused on viscous effects and heat transfer taking place within fluids mostly at low subsonic speeds. The course does not require prior knowledge in heat transfer or fluid mechanics theory. We will derive the momentum equations and total energy energy equations of fluid flow using the fundamental laws of physics and then use those to solve basic problems. ...

Numerical analysis is the branch of mathematics involved with the development of efficient methods for solving problems using a computer. In this second-year undergraduate course, we will cover various numerical methods including numerical integration, numerical differentiation, root finding of linear and non-linear systems of equations, and curve fitting. For each numerical method shown in class, the student will...

Viscous flow is a senior-level undergraduate course focusing on the friction effects within fluid dynamics. The course starts with a derivation of the Navier-Stokes equations from Newton's law and then applies the Navier-Stokes equations to Couette flow within journal bearings, to external viscous flows on flat plates and airfoils, to internal flow within ducts and pipes, and to flows in pipe systems including...

Computational Fluid Dynamics (CFD) is a graduate course that focuses on numerical methods solving incompressible viscous flow. Some focus is given on deriving the most-commonly used turbulence models (algebraic, 1-equation, and 2-equation) and how to implement them within fluid flow solvers. Sources of numerical error are also outlined along with techniques on how to assess them accurately. The course ends with an...

Thermodynamics is a second-year course giving an introduction to gas and liquid physics. Topics include ideal versus non-ideal equations of state, the first and second law of thermo, conservation of energy using the control-volume approach, the Maxwell relations, gaseous mixtures, and chemical reactions. Example engineering problems include the analysis of pressurized tanks, air conditioners, and combustors....

Come relax in my skylounge, and check out some old pics when I was a bit younger (and perhaps cuter). Also find some opinion pieces I write in local newspapers, some recipes, some pictures I took of Busan and other cities. I also store some information of interest I come across by chance (and may soon forget otherwise..) in the thread “Stumbled Upon”. There are a few techie threads on how to install...
