I'm working on my PhD in aerospace engineering, specializing in computational turbulent combustion. My focus is primarily on massively parallel algorithms and computational methods for solving fluid and structural mechanics problems. Primary work is done in Fortran (90, 95, and 2003) but recent work has me branching into python, C and C++.

I'm also interested in international affairs and law.

Also interested in applying computational techniques to sports, in particular cycling aerodynamics and performance optimization. Particular emphasis on track cycling and time trialing.

Apr 10	comment	What causes a soccer ball to follow a curved path? Could you clarify? I assume you mean left or right motion as opposed to the arc due to gravity.

Apr 6	comment	What is the term for heat generation by a flowing fluid? It is typically called the `viscous work` term.

Feb 19	comment	Are there still 'everyday' phenomena unexplained by Physics? @Bernhard RANS also needs subgrid models to represent the influence of missing scales on the time averages. These models may or may not be the same as those used in LES.
Feb 15	comment	Water vs Milkshake being sucked through a straw Do the derivation again without assuming non-Newtonian fluid and you'll see what difference it makes. It's actually a good derivation to work through. Since we're talking a straw, make sure it's all done in cylindrical coordinates and not Cartesian.

Feb 5	comment	What's the difference between these two formulas and how are these called? h also could represent the height above a surface which is probably why g was still in it.
Feb 3	comment	Radiance equation Just in case it wasn't clear from his answer, $d^2$ does not mean something to the second power. It means you are taking the second derivative of the variable.

Feb 2	comment	Physics problems requiring numerical solutions to polynomial systems? If you solve Navier-Stokes, that is a nonlinear PDE and if you take finite elements with many nodes you get polynomials of order higher than 1 (ie. nonlinear). The simplest non-linear PDE is the Burgers' Equation which actually shows shocks and turbulence but still has analytical solutions for certain initial conditions, and it has a viscous term if you want that too.
Feb 2	comment	Physics problems requiring numerical solutions to polynomial systems? Anything capable of a for (or do) loop and basic math operations can solve polynomial systems. Which they both have. And both Mathematica and Maple can be used in parallel so it's possible they could solve anything other software could, although I know nothing about how well they scale in parallel.
Feb 2	comment	Physics problems requiring numerical solutions to polynomial systems? Of course, anything really can be solved by Mathematica and Maple. Perhaps not directly but those are completely capable of numerical/indirect solutions to problems. Given enough time/CPUs of course.
Feb 2	comment	Physics problems requiring numerical solutions to polynomial systems? Are you talking about something like Finite Element Analysis? That's the solution of a system of potentially millions/billions of basis functions (typically polynomials) to understand whatever PDE you are interested in (fluid flow, structural mechanics, etc).
Feb 2	comment	When do I apply Significant figures in physics calculations? mathematical-physics probably isn't the right tag for this. But I don't know what is, mathematics isn't appropriate either.
