Dear arildno,
Thanks! It makes much more sense now. I had to look back onto my old texts but I've got it figured out. Yet I am alittle confused on the last part. I tried figuring it out but I could not figure out how to combine the two terms into one...
Dear Arildno, I am sorry for the confusion. I tried add more text and equations to show my logical flow. Thanks for your reply.
Dear HallsOfIvy, Thanks! It makes much more sense now. I am wonder if my method was what you meant by:
"Now, make sure you have plenty of time and paper, take a...
Question
Hello. Thanks for the reply. I am wondering if this is mathematically viable:
Assuming:
\frac{\partial \phi}{\partial x}= \frac{\partial r}{\partial x}\frac{\partial \phi}{\partial r}+ \frac{\partial \theta}{\partial x} \frac{\partial \phi}{\partial \theta} (1)
and
Assuming...
So I've attached how far I've gotten but I am not sure if there are any tricks because I'm stuck.
\frac{\partial }{\partial x}=\frac{\partial }{\partial r}\frac{\partial r}{\partial x}=\frac{\partial }{\partial r}cos\theta
\frac{\partial }{\partial y}=\frac{\partial }{\partial...
Hello.
I am interested in learning the mathematical derivation from Cartesian coordinates Navier-Stokes equation to cylindrical coordinates Navier-Stokes equation. These equations have similar forms to the basic heat and mass transfer differential governing equations. I’ve tried looking...
