Hi, I'm unsure as to what type of flow this is: Stream Function: psi = -ln(r) + theta Potential Function: phi = theta + ln(r) For some reason, I don't think I'm plotting the flow correctly. Suggestions/advice? Thanks!

Hi all, I've been stumped on this problem for over a month. Any guidance would alleviate my overwhelming frustration. Here is the original problem statement: Find the principal rates of deformation and principal axes for the flow given by: u = (x,y) and v = 0, satisfying the...

AlephZero, THANK YOU! Your explanantion with the example was amazing! I truly appreciate your patience with me, as I realize that my math is a little rusty (since I just started school again recently). Once again, many thanks!

Not really Laplace's Equation?? Hi all! I've been out of school for awhile and so, some of my engineering math is still rusty. While working out a fluids problem, I got stuck on the following PDE: Y''(y)}Z(z)+Y(y)Z''(z)=-1 \frac{Y''(y)}{Y(y)}+\frac{Z''(z)}{Z(z)}=-\frac{1}{Y(y)Z(z)} I know...

I'm sorry, but I'm not familiar with your notation. For the expression for \frac{\partial}{\partial y}, you used \frac{\partial}{\partial \eta}. What function are you taking the partial (with respect to eta)?? Also, for your expression of \frac{\partial^2}{\partial y^2}, are you just...

Why of course! Chain Rule, so elementary yet I didn't even consider it. Thanks! This brings up one more question: For (del^2 eta/del y^2), why is it that the answer is the square of the first derivative of eta instead of the second derivative of eta? That is, (del eta/del y) =...

Hi all! I am required to find the velocity distribution of the flow around an infinite plate that suddenly starts moving with a constant speed U_o. The solution has already been worked out, but I still do not understand all of it. The part that is perplexing to me is where they use the...

da_willem, Thank you thank you thank you! After picking over my work for about a week now, I can't believe I oversaw this rudimentary step! Your help is greatly appreciated! =)

Help! I am stuck on the following derivation: Use the conservation of mass to derive the corresponding continuity equation in cylindrical coordinates. Please take a look at my work in the following attachments. Thanks! =)
