It doesn't get any better than this if you're looking for mathematically rigorous, and physically intuitive introductory lectures on turbulence. Professor Chakraborty is a gifted teacher and his lectures are a treasure.

Outstanding lecture by Prof. Suman Chakraborty. gems from India.

Very beautifully explained, very systematic and organized. Everything covered in detail, without losing the essence or making lecture boring. All turbulence terminologies became crystal clear with this explanation! Thanks a ton @NPTEL & Prof. Suman for this

At 16:41, please could you explain me where does that expression come from if you've understood that? I've watched his past videos but no idea yet.

@@apoorvmishra6992 this info will be available in old research papers. From journals. The papers which introduced these fundamental expressions for turbulence, will have a more rigorous math of how dissipation is related to strain rate term

Lucid explanation of turbulence modeling..Thanks Prof.

Difficult subject, made easy and interesting because of the presentation technique assisted by in depth knowledge.

Thanks professor. I hope you can share a whole course on turbulence modelling. i really appreciate your great explanation

10th minute: The smaller eddies are not molecular in size, but larger, because we are not on the molecular level when we discuss turbulence length scales. It's a continuum.

Excellent lecture !Thank you Professor.

Great lecture, thanks for sharing it

extremely thankful, you saved my day

thank you very much professor, it was really helpful.!

Love this lecture

At 40:30 dw/dt is wrt to the large eddy scale then as the w is increasing for small scale eddy then it should decrease for large scale right?. In that case should it be negative. I couldn't get that part.

initially , i have a problem understanding this part like you , but i think he is right since in the cascade we have a gradual decrease in the eddy length scale. so , if we consider eddy with a little bit smaller radius than the largest eddy , the smaller one will also satisfy the conservation of angular momentum so we can apply his analysis on the smaller one

What an explanation! thanks prof.

Thank you Dr. Suman Chakraborty !!

Thanks so much sir

Thank you

Thanks Prof!

Awesome...

Thanks professor

Dear sir, I am a researcher in the field of aerospace engg. My research area is sensor & actuator FDI. Could you please tell me how to calculate the turbulence velocities along three axes (x, y, z) of an airplane using recorded flight data? The effect of turbulence is considered as disturbance in my study. I am trying to estimate the turbulence velocities using Dryden wind model under various levels of turbulence. But am not clear on angular frequency mentioned in the dryden spectra equations. I have the flight data (contains almost all the flight parameters) of a business jet for my study. Could you share your idea?

ok, why all videos about turbulence on youtuve feature a dude speaking with an indian accent?

Dear Dawn, If you are able to understand the concept properly, then I guess the accent is not a problem. Also, he is not dude. Show some respect expecially when he/she is a professor. I don't know from which part of world you are, but in our Indian culture we place Guru(Teacher) above God!!

Because Most of the INDIANS seem to know this concept well and are able to explain it in a better way than the ones who have an "ACCENT". Get it?

Great teacher in Fluid Mechanics. I majored in Fluid Mechanics too.
