around 02:00, is P:DV a product? what product is it? thank you

wonderful

excellent explanation. thank you I love you If you teach with Persian language It's will be more excellent

Wonderful methodology

How do you calculate the x and y values from the Hewitt & Roberts flow regime map?

Dear Dr. Arup Kumar Das, thank you for this open training course!

Thank you sir. A great and helpful lecture

Particle response time formula is valid under stokes regime right, meaning particle Reynolds number is 0. But when particle flows under the influence of air flow, its Reynolds no. will never be 0 right. Can we still use this formula. Or am I understanding this wrong, other way round of thinking this formula is initial Reynolds no. of particle should be zero meaning particle should be at rest before coming under the influence of air flow. Please explain. Thanks

i just want to say thanks alot for these lectures god bless you alot

🙏🙏

Sir, @27:58, you mistakenly wrote alpha*jf which should have been jf only.

Thanks a lot Prof. Wonderful. Reminded of my classes on Two phase flows taught by Prof. SK Dass at IIT Madras. My humble thanks to Prof SK Dass for his very interesting lectures. Same note of Thanks to you. Will be happy if you can introduce audience good books like Colliers, Stephen, Whalley, etc. for additional learning in every lecture of yours on the topic.

Thanks Dr. Kumar Das. The derivation of Shear in Annular is very interesting, I´ve been trying to do it a lot of times to reach Hewitt & Hall Taylor (1970) result. Do you have examples of upward liquid and gas?

Dear Dr. Kimar Das. Could you please inform me what references are used for the lectures? The symbols are a lit bit different from Todreas&Kaziimi (my references). However, they are easy to understand with your explanation, and there is an interesting approach for the models. Thanks for your kindly attention, and congratulations on the excellent lecture.

Dr. Kumar Das..... Excellent lecture

I am doing a project using Shan and Chen pseudopotential method. I did not use anything to capture the interface separately. But using this method also interface evolves. Can you explain how this happens?

Flow boiling starts after 28:00

Thanks sir

Thanks sir

Thanks sir

Very good!

friction varies with length in actual. How can you take it out of integration as a constant?

sir G is mass flux right? superficial velocity is given by j isn't it?

What is important model sir in homogeneous

Very good Lectures! But with the pointer appearing in the videos would be better yet.

Sir can you suggest a book related to this topics

very nice very helpful ,thank you !

Dear Sir, during the water electrolysis inside the cell hydrogen and oxygen gas are produced from the water. so is it multiphase problem?

helo sir ; could we use the VOF method for capturing solid liquid interface ??

Could you recommend me any book in order to understand better this phenomenon and have a better understanding of the equations of slug flow?

good very good you are amazing teacher

good

very good lecture sir. can we get that presentation for our future reference ??

very helpful, thank you very much

Good lecturing Sir, Thank your very much

can you explain bounce back boundary conditions of lbm?

A very interesting and descriptive explanation of the different two-phase flow patterns. Thanks for sharing.

Thank U sir, It's really good, but your English still has huge space to improve.

good lecture

useful for competetive exams

excellent explanation. thank you

what is the difference between superficial velocity, terminal velocity, and bubble velocity

How to find superficial velocity (j) in a closed-loop capillary

这咖喱味的不看字幕真听不懂

really help full for amie course

But some of us do not work on linux.

Some programming step how it will be implemented
