Air flow analysis on a racing car using Ansys Fluent tutorial Must Watch Kindly find the below link to download the hands on file funmechanical.blogspot.com/201...
Nice tutorial! Thank you for post! Just a suggestion, you should make a tutorial explaining by your own words what's happening , like a step by step. Regards! =D
With all due respect, I believe that the domain is too small. While being a very good tutorial, this might mislead beginners believe such a small domain is OK for their simulations. Especially when the outlet is too closed to the car, with not enough wake development. Even with the pressure outlet (zero gradient in terms of velocity), this domain is still too small.
excellent tutorial! but can you tell me how to decrease the size of the bubbles when animating the streamline? i found the bubbles are so big in my case. My case is also car aerodynamic just like in this tutorial, but i have no clue how to decrease the size of the bubbles when animating streamline.
thanks for the tutorial of yours first of all. Secondly, I have master degree thesis and wanna clear up it to you. Could you help me out for doing it in Anysis ? Wait for your support. Thanks a lot.
Hi, I NEED HELP PLEASE. in my case, the vehicle is not solid but a shell/surface. I can't subtract the vehicle geometry from the enclosure. What could I do? Thanks!
will you please help me in simulation of leakage flow due to pressure difference brtween two parallel plates, where one plate is stationary and other one is moving with DYNAMIC MESHING
hi thanks a lot for your video. can you make a video of fluid movement near the apartment?? i have a hard time with it.... i dont know how to make no slip condition on ground. also i dont know how to make enclosure 0 between gound and apartment. and i want to make other enclosure surface with free slip condition...... can you help me??
Hi sir, im not able to select any of the body while doing enclosure. even if i click on generate in not able to do that. can you tell me any other way?
GlobalCAD hi sir, i really stuck and dont know who i want to ask. i really need your help. my case is to analyse flow between 2 identical buildings. can you make the video how to do that especially the part of the boundary conditions? 😓
Hello! Nice video. If I am importing an assembly with different parts how can I use boolean in order to join them? Would I use unite instead of substract?
Clearly, a wind tunnel helps us to visualise airflow over a car. But, the objective is to improve airflow in the real world. In the real world, the air is more or less stationery, the road is stationery, and it's the car that moves - the inverse of the wind tunnel situation. Definitely different scenarios. May I ask - when using CFD for race car design, does the CFD software attempt to mimic the wind tunnel or the real world?
respectfully you have misunderstood the principle of general Newtonian mechanics and also its application in fluid mechanics. about your comment " the inverse of the wind tunnel situation" : when a air is stationary and car is moving , the car has to move the neighboring air molecules of its front by the speed of itself, so it should carry the inertia forces due to changing velocity of molecules to speed of itself(Newton's second law) but in air tunnel wind , when air is moving at the desired supposed speed of car , when this moving air collude with the stationary car so it stops and the car has to bear the inertia force due to changing the speed of air from the desired to zero. the force in this situation is completely equal to previous one. above description is expressed loosely, forgive simplifications. finally i think you should understand the conception of engineering, it differs from being a scientist. the science seeking for perfect solution without any error and most of the time it is not possible but engineers looks for finding solution for the domain not for perfection. wind tunnel is answering well to real world engineering problems but has its limitation for super advanced topics . good luck a graduate of mechanical engineering
Yes actually you are right, but from the respond of dear Tristan I got that he is not familiar with the conception of reference frame, so I had an intention to express the de facto conception behind it.
praveen oswal Ansys works with relative pressures, not absolutes ones. So PRES=0 means atmospheric pressure and PRES=-1atm means absolute void. (Pardon my english)
hi, guys, can anyone help me in solving this " how can I create a single body geometry in Design Modeler since I have 38parts and bodies of my imported geometry". Thanks in advance
Nice tutorial! Thank you for post!

For our simple project this is extremely helpful!
Thanks!
Awesome tutorial! Thank you so much for sharing your knowledge. Helped me a lot!
Very helpful, learned a lot in the past using this
What a wonderful tutorial. you made a good car. Thank you.

I am using fluent on Wells turbine can you tell me how can I find pressure at any point after turbine...?
This tutorial is very helpful thank you..
With all due respect, I believe that the domain is too small. While being a very good tutorial, this might mislead beginners believe such a small domain is OK for their simulations. Especially when the outlet is too closed to the car, with not enough wake development. Even with the pressure outlet (zero gradient in terms of velocity), this domain is still too small.
Definitely you re right. You must increase the length of the enclosure about 20 times of car length near to pressure outlet.
Is the domain the box around the model at 3:10? If so, do you have to create it before you enter the model into ansys?
Also, the ground should be against the wheels. Unless the car is meant to fly of course ahah
@@piereligiodisante hahaha I was wondering this...
Awesome video! By the way, could you please make another video on how to draw the car geometry?
Thanks for this video. It was very helpful.
Hello my fluent is a newer version and seems to different from yours. Is there anyway to go back to using the older fluent setup?
Thanks for your help :) Great video dude

any suggestion? car knuckle analysis
thanks!
ı think you should define the areas(referance values part) solve from results section 'projected areas' becasuse model is 3d

yes,u can also change the type of enclosure to cylinder if u want and continue with the same procedure....

where is the boolean operation command for ANSYS 19,urgent ! HELP!
This video make me want to buy youtube premium. Thankyou anyways
good for basics but not for accurate solution

Hello! Nice video. If I am importing an assembly with different parts how can I use boolean in order to join them? Would I use unite instead of substract?
am not proffesional but in my opinion you can assemble them in other CAD program as solidrowks or inventor then import it as a one assembled part
Yes! Works just as well

Why isn't atmospheric pressure considered?

can you give me the validation data of it

Did you find a solution ?
I'm looking for it too.
how to read that design is good or not, there is no such good video, only procedure to obtain results are there.

hi, guys, can anyone help me in solving this " how can I create a single body geometry in Design Modeler since I have 38parts and bodies of my imported geometry". Thanks in advance
Hi..
You need to modify the geometry in the design software itself.
what is the geometry?
you need to have the geometry properly connected
