Solution of a matrix equation
Hi Guys,
I am currently doing some analysis that requires me to solve the following matrix equation:
ri = v * Ai * v'
where ri is a scalar, there are many of these (>n) and they are all known....

Thanks Ahmed,
You are absolutely correct - this isn't strictly the Coanda effect as it involves liquid water in quiescent gas. I was using the term in the sense that the 'Coanda effect' is used to...

Hi Guys,
I am currently looking at the condensation of gas onto a sphere. My current assumption is that the condensate film layer will remain attached to the sphere, remaining on the sphere's...

Reversible flow
That's what I've been thinking too - it's the only way that the argument can work out.
It makes some degree of sense. For inviscid flow (going from left to right) over a symmetrical airfoil, say,...

Thanks for your reply Mat,
I'm not referring to the shock polar - I guess what I'm really asking about is the reversibility of the Euler equations. I'm dealing with transonic flow over an airfoil...

There's an analytical function for the thickness of a NACA00XX airfoil.
The upper surface of the airfoil is given by:
upper(I) = thick*5.*(0.2969*sqrt(x(I)) - 0.1260*x(I) - 0.3516*x(I)^2 +...

Hi Guys,
I'm reading through some literature on transonic flows and came across a paper that says (I'm paraphrasing) that because the Euler equations do not contain a viscous term that expansion...
