Analytical solution to this integral?

Dear All,

I am currently seeking an analytical model for condensation upon various geometries. I am updating a legacy code, which needs an analytical expression to be entered.

My work on this...

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...

Coanda effect, condensation on sphere

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...

Reading graphical data from printed materials

Hi Guys,
I am trying to compare some numerical results from my work with those appearing in the literature. I have some printed graphs (simple line graphs) and was wondering if anyone knows of any...

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 +...

Euler equations & expansion shocks

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...

Post Transonic Dip & Phase lag

Hi Guys,
Welcome to my first post! :D

I'm reading about transonic aeroelasticity at the moment; it is well known that the flutter speed of an airfoil decreases substantially in the transonic...
