I completed MSc and I had this module but I was not understood fully. So, I watching whole series. Really good lectures with an excellent explanation. Many many THANKS to you SIR and your team.. 🙏🙏
my left ear is more educated than my right ear
Continuous earphone use will surely degrade your auditory sensing
I didn't eat breakfast before I went to church.
equation number 3 is not true
The effort you put in teaching the hardest concepts in the simplest possible way is something at par
One of the best explanation, I have watched
Good
Good one, Sir.
Thanks. He is in if the best teachers. How to get the list of whole lectures?
Can someone explain how to calculate the nx and my values
what is the name of the teacher? he is very good
bro that thumbnail did you wrong
This is lecture 2, not lecture 3.

Very good explanation sir.

Thank you man for this video. This is fantastic!
Sir your teaching style is outstanding. You speaks so politely that any can understand the topic easily.
Nice, by the way, Does Von Neumann stability still work for the STEADY STATE?
I guess it does
Extremely wonderful

I still have a lot to learn.
same
Excellent!!! proof of deformation ratios.
Congratulations! you have a very good way of explaining ...
Congratulations! you have a very good way of explaining ...
excellent explanation!!!
Excellent!!
excellent explanation!!
Excellent course!!!
Pic is not clear
wow he made that seem so simple thanks a lot! :)
sir,Your class helped a lot sir..sir i joined as researchscholar in the area fluid dynamics...sir if I have a doubts may I ask you sir.Thank you
he will not reply he has other works.. u can ask though i am interested
Clearly explained ... Thank you sir !
Pls go through, like and subscribe my presentation on Vehicle thermal management theory. lnkd.in/g5vY243
Sir, could you solve PDE as analytical solution?
Çözüm elinde mi
How to come w23 400
I want to use a triangular pipe for high pressure, high volume water flow. Is this a good or bad idea? Can I DM you about this? Thank you very much!!
for x -momentum equation you took v - control volume and this is the wrong sir

Sir, could you please tell me if you neglected the cell length to multiply the products of normal components and gradient components. could you please explain me what I am missing. Thanks a lot in advance.

it should be (Ni - 2) * (Nj - 2) number of algebraic equations to be solved at 12:25 as we saw in the second lecture where we had 5 nodes in x and y directions and we solved only 9 equations after eliminating the boundary nodes.
Great explanation, Thanks prof.
excelent lecture! thanks!
Bro I love you, talking bout coming through in the clutch
i think there is some missing variable in the final equation .there should be -800 W22 another variable .
What is w
sir in this tutorial i didnt understood that how the values come 100, 1000 and 400 can anybody please explain me or give me hint
pick a grid point ,move along y axis up and down and then write 400 in front of it, again around the same grid point move along x axis back and forth and then write 100 in front of it. lastly put -1000 in front of where the point you picked. this will only work for central difference scheme when the delta x is 0.1 and delta y is .05 meter.
Replace the values and solve. 100w32-200w22+400w23-800w22=-1000 100w32-1000w22+400w23=-1000
Why can't chequer board problem arise in Thermal Flow fields?
24:38 Isn't it supposed to be a quasi linear equation? How does u^2 make it non-linear pde?
Thank you, sir. Great tutorial indeed. I am not a student of engineering stream. But I understand each and every step of your lecture. My question is if the solution doesn't converge what does it mean??
it can be mean couple of things wrong BC condition, wrong approximation formula, or eqns are not linear and maybe the matrix A is not unique.
The coefficient C really depends on other factors, such as: dP/dz = (32u/Lc^2) *w Where : Lc=Characteristic length of rectangular duct u=Absolute viscosity w=velocity in the z direction. This equation guarantees that there is a diagonally dominant matrix, and therefore, there is convergence.
Nice sir.i understood
good lecture
