    There are two main types of fluid flow - laminar flow, in which the fluid flows smoothly in layers, and turbulent flow, which is characterised by chaotic motion and large amounts of mixing. In this video we explore the differences between these two flow regimes. We'll cover how Reynolds number can be used to predict which flow regime will occur for a specific set of flow conditions. And we will look at laminar and turbulent flows in pipes, and how the flow regime affects the pressure drop in a pipe. We'll also investigate why it is so difficult to simulate turbulent flow, and we'll look at some of the different Computational Fluid Dynamics methods which can be used to simulate it.

      I cannot move my eyes from screen, it is so beautiful videos

    9. Shawn • Chemical Engineer

      WHERE WAS THIS VIDEO WHEN I WAS IN MY FIRST YEAR OF CHEMICAL ENGINEERING!??!

    10. miniCHANGMIN

      Thank you for making this vdo. It's absolutely useful vdo and make me clear about this topic.

    11. Vimal Bhardwaj

      Great explanation

    12. Aakash Rai

      Inertia force = ρAv² Viscous Force = μAv/L hence reynolds number = Inertia force/ Viscous force = ρvL/v

    13. Harry World

      Thank you mate. It really helpful and better than book

    14. Emmanuel Erinwusi

      Thanks so much for teaching. God bless you!

    15. Sadra Seifi

      Please cover more concepts about dynamics

    16. To Vip

      Please designer of this humble video: At seprom.info/clone/video/nKRip7t_YIeEkq8.html it should read "delta PRESSURE (PA)", otherwise physics has a new dimension: negative pressure ;)

    17. HIRA RAMA

      Thanks from india ❤❤

    18. sagar khadka

      Great content for turbulence by far.

    19. Modelis Team

      I think your suggestion, that in the case of fluid flow thru the tube in formula Re=ρVL/μ (L) means tube diameter makes no sense. This would mean, that increasing the tube diameter would increase turbulence. In turn this would mean that blood vessel should be supper tiny to have laminar blood flow in it?

      Loved it... So is there a whole subfield of fluid dynamics trying to find the optimal roughness for building materials in pipe construction? cuz I'm wondering if it's cheaper just to do that instead of trying to make something perfectly flat if a laminar surface is what you're going for...

    23. Grant Gudmann

      thank you thank you

    34. Otavio Duarte

      Your animations are amazing, what software do you make them on? Congratulations on the channel.

      1. Otavio Duarte

        @The Efficient Engineer Thanks for the answer. Best Regards

      2. The Efficient Engineer

        Thanks Otavio - I use Blender for the animations.

    35. aki

      I love fluid dynamics especially turbulent flow. This is an important problem for industry to design car and combustion in engine etc.

    36. Thejas v s

      amazing content. im here studying for exams

    37. amzar asri

      Background music name?

    38. Benedikt G.

      Dang this is a good video. I've watched so many bad or lackluster videos about fluid dynamics and especially turbulence on SEprom. This one is just great, very well layed out and structured, and everything is correct (ly explained).

    39. Chewie Lewie

      Could’ve done with this during my ChemEng degree lol! Great videos 👍👍

    40. SHAHID NAWAZ

      Great work by great man 💕💕💕

    41. FAIF3A

      Just to be a bit nit-picky, your NACA airfoil shown at 11:20 timeframe states NACA0012...the NACA0012 airfoil is symmetric (i.e. no chamber). What you have shown looks more like the NACA 23015 (cambered). Great demo nonetheless!

    42. 노영진

      So if there is a laminar flow at the edge of the pipe, there must be a sheer pressure because of the velocity difference at the center of the pipe and the edge of the pipe. Then, I think it could possibly generate an eddy. Then, should we see it as a Turbulent or Laminar??

    43. ARINDAM MANDAL

      Superb animation, loved it❤️

    44. Mahmut Tanyeri

      I haven't seen any instructur who explains that complicated stuff as much simple as this

    45. Jonathan Vogt

      I'm a CFD engineer and I'm always looking for accessible ways to introduce fluid mechanics and CFD to people. This is a great summary :) Well done.

      Omg I was listening to music and this came up in the recommendation and because of the thumb nail i thought it was just a weird song 😭😭😭😭

      1. Geordon Worley

        The music on this thing at 2:00 is really good. Do you know what kind of music it might be? It could be like music you were listening to before you got here.

    79. Aveek Kumar Pramanick

      just wow.. please make a video on gears

    80. Yu Bunthiam

      I want to make a laminar air flow in the the 20 ft container. Is it possible? Anybody can help.me?. Thanks. For your good video.
