What Is CFD

Wednesday, April 11, 2012

Okay, you just taking your final project, getting your own supervisor. And your assignment is in Mixing Laboratory. after first consultation, you got assignment on simulation using CFD.

Wow, wow, wait… what’s CFD?. Is it so difficult?

That’s my first question when entering mixing lab?. Why should I take this assignment?. I’m bad in Transport Phenomena, and now must simulate fluid Dynamic?.

He he, if you do think like that, then you just like me ten years ago. But don’t worry, when you can think this clearly, you can solve this assignment no matter what.

So let’s talk about what we face. I will give you short explanation, but I hope it’s clear enough for you to understand:

What is CFD Stand for?

CFD stand for   Computational Fluid Dynamics

What is it?

simply say, you solve fluid mechanic equation using Numerical Methods. Usually it’s Navier Stokes equation if you ask

So, I must understand Navier stokes?

If you wanna be professor, yea, you must be able to solve Navier stokes equation by hand. But if you are BSc degree, I think you only need to know global or the philosophy behind this equation. You are not solving this equation manually, computer will do this task for you. All you need to do is setting boundaries

Is it Interesting? Something like solving this thing?

I can say, VERY INTERESTING. Maybe this picture will burst your spirit and realizing that your choice on this assignment is trully Right
