Introduction to Fluid Machines and Compressible Flow by Prof. S.K. Som,Department of Mechanical Engineering,IIT Kharagpur.For more details on NPTEL visit nptel.ac.in
I have so much of respect for IIT's just because such teachers ......Thanks a lot sir.....very well explained especially physical intention of the chocked flow at last......HIGH RESPECT 🙏
At 25:30 even if the pressure dropped from the sonic condition , I agree that flow can't accelerate. But my question is why velocity not increased by decreasing pressure and flow start to decelerate as supersonic flow through the converging duct?
I have a Question. Lets consider the flow is chocked and the velocity at throat reached to Mach 1. Now if I further increase in back pressure, will the flow from Nozzle remain chocked or will reduce to subsonic speed? Because if we increase the backpressure, the information can not travel through the Nozzle throat. so can it keep on running with chocked flow? I am confused at this point.
Very honestly, coming from someone who has watched a lot of online tutorials, he is probably the best one to explain a concept.
As far as Engineering is the best always prefer NPTEL over any other it may take long time but it's long lasting
God of fluid and thermal

tomorrow is my endterm and seriously!! I am studying it for the first time...and understanding tooo!!!! Amazing Som sir..RESPECT!!
Best faculty in fluid related subjects in "IITS"
Best teacher of TD and FM ever
These lectures are oozing with knowledge..
Thank you so much !!! it helps me a lot. Much more clear than what my professor explained !!!
Xin Shen correct
Best teacher of my life
God bless you!
What a lecture Sir, helped me a lot in understanding compressible flow at microscopic level too.
Respect for you, Sir. You are really an amazing professor!!
Explained a very difficult topic, in a very simple manner!
Thank you very much Prof. Som and NPTEL!
best professor at nptel
Thank you sir..This explanation was so clear and helpful..!!
Gold
nice teaching..sir..easy to understand.
your voice like.......mithun chakravarti...😀😀
Amazing concept...
someone to explain why the disturbance could not effect in reference to its relative and absolute velocity as put by the prof,please
जियरा खुश होई गवा सर g
Thanks sir, awesome teaching
Thank you, very clear explenation.

Got the answer in the closure of this lecture. 36.00 min onwards
If you can explain me who do the maximum mass flow rate occurs at minimum area not able to catch this point
This is some good question ⁉️
Thank you sir

Isn't it supposed to be -(gamma + 1)/2(gamma - 1)?

They give not physical intuition, they only give mathematic interpitation
I guess this has to our duty to find the Intuition from mathmatical interpretation
got it
what is stalling
