2 million cells for a 2D aerofoil in subsonic flow?

Well, it relates back to the proper alignment of the equipment with the flow direction as well as to which static port is used because you have to use the right one... I have to revise, I don't remember all the details.

The pitot-static probe has to be properly aligned with the flow so if you're flying at angle of attack or at sideslip angle you're note measuring something meaningful. And that's there reason why aeroplanes have more than 2 pitot tubes at different positions and angles. Also, sqrt_9, if your...

Raymer's Aircraft design; A conceptual approach and Anderson's Aircraft performance and design have lots of information.

I think it's the first one. Yimage = -Y, Ximage = -X, Zimage = Z

I don't quite understand what exactly you're asking but physically, this kind of shapes enhances the mixing of the hot and cold streams with the freestream flow in order to reduce the noise. Better mixing leads to smaller length scales which means higher frequences hence faster decay.

Maybe it's because "engineering" is too broad. In which area are you mostly interested? Aerospace engineering? Mechanical? Automotive? Electrical? Civil? Nuclear? Computer? Environmental?

Thermodynamics: An Engineering Approach, Cengel and Boles

I think it's different for power-producing and thrust-producing powerplants.

Ferrari managed to take the best (?) out of their engines for the 458 Italia by extremely fine surface finishing inside the cylinders. Surface roughness means a lot in such areas. Moreover, generally speaking, the way in which the fuel is mixed with the air affects the combustion process which...

Yeah, I had in mind the ARA's transonic wind tunnel in Bedford, which is cooled for that reason ;) http://www.ara.co.uk/services/experimental-aerodynamics/test-facilities/transonic-wind-tunnel/

Indeed, this is kind of odd especially in a wind tunnel facility where you want the temperature approximately constant.

Meanwhile Matthew, I think I found the solution, provided you know the characteristic length of the tested body. Re=\frac{ρuc}{μ} [1], where c the characteristic length. M= \frac{u}{α} hence u=M*α [2] \frac{1}{2}ρu2=K , where K is the known value of the dynamic pressure. Hence...

I would, and I'm sure Matthew would too, appreciate it if you could right down the solution process with all the equations...

He doesn't have the density :p
