Any of your guys have CFD knowledge?

Ok heres the problem I face, there is a question I have been given but I am damned if I can make ends meat of it.



Basically the questions asks, by using dimensionless parameter try to normalize the Navier Stokes equation.



Now my Uni friends though you differentiate the equation I have been on cfd-online but to no avail, I think it may be a little advance, the rest I can do like the closure problem etc I just do not get what he is trying to ask?

Whoo boy, there’s a question out of left field for a detailing forum.



It sure never hurts to ask but don’t hold your breath, look how hard it was to get through the “plane on a conveyor� thing.



My gut reaction is that normalizing equations to dimensionless parameters is a pretty common tool for simplifying and standardizing calculations. Your basic harmonic oscillator is described by a second order differential equation and the behavior of any spring-mass-damper system can be described in normalized form by dimensionless parameters like Q and, uh, darn, this keyboard doesn’t have an omega or tau key. But you know what I mean. If you know the natural frequency and damping factor you know how it will behave.



I suspect that by knowing some dimensionless parameters like, uh, hell I don’t know, Reynold’s number, Froude number or whatever you can characterize a standard solution.



My brain hurts!
