Understanding Laminar and Turbulent Flow

Be one of the first 200 people to sign up to Brilliant using this link and get 20% off your annual subscription!

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.

This will allow me to create more high quality videos covering a range of engineering topics.

It feels criminal watching and learning from these videos without paying for it. Absolutely 10-star quality content.

You do such a great job explaining engineering principles. Especially with your good quality and simple animations. I’m currently learning Fluid Mechanics, and this is easy to understand and interpret. I think you should really start your own online learning program in which you continue to teach these fundamental engineering principles. Like statics, mechanics of materials, structural analysis, fluid mechanics, dynamics, etc. Keep up the good work !

You have such a class of making other people understand. Actually every Engineering student will agree with me that no Professor can illustrate the topics so easily & a proper way to Understand. Thanks a lot 😍

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.

Wish these videos were available when I was getting my undergraduate degree in engineering 24yrs ago. They are great!!

"When i meet god, i am going to ask him two questions: why relativity? and why turbulence?, i really belive he will have an answer for the first one"

Whoever you are....simply stunning!! Really great effort towards establishing this YouTube channel & I'm pretty sure that your channel going to rock on soon🔥🔥🔥

[amiraliyazdan]

You guys are the best, I passed Fluid Mechanics on my bachelor program almost 10 years ago and I almost remembered everything by spending 15 min watching this!! Stunning!!1

I've seen some of your videos and I can confidently say that even after graduating from university, I'm still learning much of the basics from your videos. You clearly explain theoretical concepts well without getting too convoluted and technical in the mathematics and equations. Thank you for your hard work.

I won't be surprised if in the future, you would branch out to more specific disciplines such as mechanical, structural, and geotechnical engineering. I will selfishly request that you might do more videos on structural analysis and even possibly nonlinear analysis, haha. But please keep on doing more videos like this. This laminar vs turbulent flow video brings back a lot of memories from my fluid mechanics class even though I will no longer use them because I'm in structural engineering.

I watch your videos to understand things that I thought I already knew. Your langauge is pretty understandable even though I am not native speaker. Keep it up Sir, greetings from Turkey.

This is an amazing video. My son, who graduated from the Colorado School of Mines, tried to explain this to me years ago. I never understood it all that well, but now I finally do. Your diagrams, animations, and explanations are absolutely outstanding for one who seeks to understand. Thank you.

I adore these videos. I´m currently on my first year studying for my Aero 1 class, and this has been helping me so much in grasping a better understanding of the content. Just the graphs and listening to the explanations help so much, most questions are supposed to need a theoretical answer so thank you.

[prateekksrivastava]

This is one of the Greatest step towards Education!
I must thank the person who is making such videos, Students across the globe who can't afford to get such awesome lectures also got the Opportunities to learn and to imagine and to Appy.
1-2 MILLION students are goint to follow this channel within a span of 2-3 years! But this channel must be promoted!!! 🙏❤❤

[Azbikerboy]

Incredible clarity. I never understood this fundamental concept in school 20 years ago. It was just presented to us as plug and chug and move on. Now I'm trying to get the cobwebs out and finally get a PE license and this is very helpful. Thank you so much!

[striking_chords]

This is brilliant! It's the ability of a genius to explain complex concepts with such simplicity

[vx]

This is such a detailed and educational video, thank you very much as this will be beneficial in further understanding CFD.

[mibrahim]

you gave me a better revision and understanding of my fluid courses at university 6 years ago ..
THANK YOU !

[explanationwithsushil]

It's humble request to u sir pls keep posting such videos, it will help a lot for economical backward students 🙏🙏

[himansh]

Mr you can always have a blessed night's sleep knowing you made a difference in this dark gloomy world transcending beyond borders. Thank you. ❤️

[maged]

I'm speechless! Incredible video, and explanation! Not sure why there are 2 dislikes, but I'm sensing they are jealouse of your work. Keep it up!
