 Forum: Main CFD Forum July 28, 2010, 10:00 Replies: 3 Views: 634 Posted By technophobe 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...
 Forum: Main CFD Forum July 8, 2010, 17:25 Replies: 1 Views: 611 Posted By technophobe 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...
 Forum: Main CFD Forum February 15, 2010, 12:27 Replies: 4 Views: 1,198 Posted By technophobe 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...
 Forum: Main CFD Forum May 5, 2009, 10:38 Replies: 4 Views: 775 Posted By technophobe 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...
 Forum: Main CFD Forum April 28, 2009, 14:08 Replies: 5 Views: 1,248 Posted By technophobe 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 +...
 Forum: Main CFD Forum April 26, 2009, 17:59 Replies: 5 Views: 1,248 Posted By technophobe 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...
