COMPUTATIONAL FLUID DYNAMICS | CFD BASICS

In this week’s video, we talk about one of the most discussed topic in Fluid Mechanics i.e. Computational Fluid Mechanics (CFD). CFD is a branch of fluid mechanics that uses computers to simulate fluid flow problems. We talk about the need for CFD and the various steps involved including discretization(meshing), solution and post processing. We also talk about the fifferent forms of the Navier stokes equation that are used to reduce computational effort from direct numerical simulation(DNS), Large eddy simulation(LES), Reynolds Averaged Navier Stokes (RANS)equations.

The tutorial on ANSYS FLUENT will be uploaded soon.

Hey! If you haven’t come across our channel yet, we are five masters students (Nikhilesh, Kushal,Ankith, Akshar and Sanjeet) pursuing Aerospace Engineering at T U Delft in the Netherlands and make science videos every week. Please do subscribe to our channel and share the videos.

You people should be acknowledged for your work by great academicians..keep shining

[bhushan]

1st video on YouTube who removes doubts about CFD kudos to you guys..

[rajasgaikwad]

Thanks a ton for making this video! The level of attention to details is unparalleled, feels like I've read an entire book in this 15 minute video. Keep up the good work guys! Your efforts are very much appreciated. Cheers!

[benjaminkohweien]

This is very informative for my final year project, thank you.

[SIRAC.KILINC]

I can't pass this video just by watching. I both liked and commented. Thanks to two of you👍

[Ameerscholary]

guys u just made huge shortcut for fluid dynamics thnx alot for this video

[uvaraniaka]

Hi guys, this video is really informative to clearly understand the overviews of CFD. Randomly i saw this video and very impressive of you guys.. clearly explained how all the things worked out in CFD... keep going

[aakashsr]

Excellent work!!! Not only the fluid flow, your flow of explanation is exceptional...! Cheers both you guys !!!

[Tamb]

Compliment, very clear without report confusional or wrong info

[EAR.Pakistan]

Great dears. I hope u will reply my question too.
1. In my CFD analysis, Total pressure is not being equal to static pressure plus dynamic pressure. Where I am wrong?
2. Why velocity profile is near walls.
3. How to display maximum / minimum values of results in graphic display.

Watching you from France. Very instructive ! Thank you :)

[venkatabrahmatejaharidasu]

This is really a great video.... I still can't understand why there are only 3k subscribers..

[raghukoduri]

hope u continue the CFD series....very informative and thnks a lot

[AKannadiga]

Found this video very insightful. You guys have explained all the concepts very well. Waiting for the ANSYS video. Please upload it soon guys. Keep up the good work!

[mbinacedric]

thank you for your explanation, it is so clear!!!

[bharatbhusanrout]

Superb bro .. u are make this cfd very easy

[kottapallibalamuralikrishn]

Thank u sir, this vedio helped me a lot

[harshakorlur]

Very Good Brief Introduction for beginner like me. Thank you very much.

[rameenmeerann]

Wow I like the video of CFD with simple explanation, may continue with a real simulation as examples. Great
