WHAT IS CFD: Introduction to Computational Fluid Dynamics

What is CFD? It uses the computer and adds to our capabilities for fluid mechanics analysis. If used improperly, it can become an incredible waste of time and money. With the right engineer, CFD can be cost effective, incredibly informative, and offer unparalleled flexibility. But what is this wonder of modern science? Learn more about this expansive tool.

I love those videos, but when seeing how many different factors have to be considered it's now clear why there are no deep dive CFD calculations in Watersports like Kayak, Standup padlling hulls etc... but your videos are great to understand where the different strengths of certain boarddesigns will be.

Very nicely explained. Every university student taking their first fluid dynamics or CFD course should see this video. I also agree with your statements of asking CFD vendors to prove the accuracy. A Proof of Concept exercise is a perfect way to do this. CFD is indeed complex and it starts with the meshing, which requires a lot of knowledge and can be very time consuming. There are fortunately a handful of companies that are making great strides in simplifying the process. One that is very accurate and has developed a marine specific template that works very well can be viewed in our channel.

What to say - excellent topic!
I appriciate yours presentation with so much love for topic like CFD!
In general for my topic in hydraulic and researching deep reinforcement learning control a heaving plate of breakwater this dynamics model of the wave - plate interaction based on an in-house COMPUTATIONAL FLUID DYNAMICS (CFD) solver. Thank you for Accuracy and how to achieved DMS! It is obvious how The Fast Fourier Transform (FFT) analyses indicate that heaving motion of the active - controlled plate can reduce the amplitude of fundamental component of transmited wave, compared to fixed plate. Yours presentation with big knowledge can be direction - path how to prove the potential of CFD with DRL (that is utilized to find the optimal strateg for wave dissipation) actively dissipation ocean waves. 👍👌

I loved this video! I've never taken a CFD class, however, this video made me understand in 13 min what CFD is. Btw, your presentation skills are neat! I will defend my thesis tomorrow and your presentation style will help me as a reference.

f1 engineers do use CFD to predict flow, then wind tunnels with a scaled model and even flovis paint on cars to the real flow ! so on this exemple i think they know how accurate a simulation is and how it impact the workflow !

You can win a million dollars if you even prove there is or isn't a solution to the naviar stokes equations

Hygenberg said "When I die I would have two questions to God, why Turbulence and why relativity, and I really think he has the answer to the second one"

I majored in Naval Architecture.
Works well done. Really.
If this existed 20 years ago, our days would be easier..

Just your regular Engineer, this was very great to watch and learn.

[thureintun]

been searching for an explanation like this!!
Thank you sir

Sir could you please post a video on how Ship Hull-Propeller-Engine are matched (With Example & calculation) ? How to determine attainable ship speed?

I would like to recommend Particle-based 3D Fluid Analysis Software.

Great, Excellent, Magnificent video.

This is a great video. The tip in the end what to worry about is really helpful too!

But what is CFD ultimately trying to calculate? Is it just trying to find the *drag* of a certain hull shape at certain speeds? I ask because that's what I'm most interested in, but I hope it can take into account the rotating propeller too, and all the water swirling around it.

Great video but as usual with all technical/special explanation the audiance is limited.
This is not fair.

[RockitMan-eytx]

Can you produce a video on Gate Rudder tech? Great channel!

[OpenFOAMbasic]

I've heard your explanation of computational fluid mechanics well. By any chance, can you recommend me a program that I need to work on? And can you make a video of the program? That'll be a very useful resource.

[dadangtriarsaputra]

thank for information! I like this video

[trisnrik]

Which stocks can I analyze with CFD? does TSLA work on CFD?
