ANSYS CFD Tutorial: Multi-Phase Flow | Drag on Hull of a Boat
Welcome back to The Engineering Guide! In today's video, we will be setting up a CFD Fluent simulation to model and analyze multi-phase flow, using the drag on the hull of a boat as an example use case. At first, we will take a look at the problem to become familiar with the geometry, boundary conditions and other variables that may be of importance. We will then jump into workbench and use fluent to perform the simulation.
In this tutorial, you will learn:

Great tutorial. Thanks
can u share the step file of the geometry
How can we put a barrier insted of the wall? I would like to do the car crash to barrier and check the result of barrier.
Thanks
This video was very helpful for my assignment thanks
If you have a course, I want to join
Hi, thanks for such a good video. I am having an error with my mesh- "The Quad Mesher failed on one or more faces" Error seems to be with the upper left hand face- could you offer any advice please !?Thanks
There is negative results of pressure at 43:59. Anyone know why ?
This is, by far, the best Ansys Fluent tutorial I have watched and applied in my 1.5 years journey learning CFD! Looking for more ;)
Why didnt you specify Gravity for this case
Bcz air speed is high and downward force due to g on air is negligible
I do not know how this video does not generate more traffic. Absolutely genius. Helped me very much! Thank you for your gigantic effort ❤❤❤
i mean not everyone is a engineering student which additionally also requires to do CFD
I am interested in how the software decided on a failure condition and split the model in two. Also, how does the material model define the plastic behavior above the yield point? Is this plasticity strain rate sensitive?
Very good video, very detailed, thank you for making such a wonderful video, perfectly taught me the basic explicit dynamics operation and solved my problem, thank you!
My geometry has a question mark
how was moving heat flux added in circular path
I am doing this for a circular weld and facing problem to choose vertex as a circular path does not have a vertex please help me with that
Have you calculated the case that considered the attitude of the boat? I got some problem with dynamic mesh 😢
Thank you very much for this video. I have solved my problem
Hi. I have a question. Did you consider flow as steady or unsteady ?
It was taken steady in this video
Thank you for your video. Could you share geometry file?
This is incredible! Thank you for uploading this.
how to model tensile test for lattice structure
Hi, thanks for the video, I have a question, where I could find the plot of Cl vs AOA? I mean about other airfoils
Hello, I watched your videos; it is very good, but is it possible to rotate the airfoil by giving different AoA in the same mesh? I tried doing it, but an error is popping out. I would appreciate your guidance on it. Thank you
Excuse me! Can you share me the geometry file? Thank u so much!
Did you get the geometry file ?

Hallo and thanks for the Video:) Does the Number of -4604 N (39:26) refers to one half of the symmetry or both halfs?
Hello, thanks for the video. But how can we input difent velocities to the two phases, one velocity for the air and another for the watter? Thank you
Very good explanation E Guide...you just make easier for beginner thank you so much for such a details video....My request you to please make similar video for wing analysis also..
I am trying to simulate same but my body does not move even giving a velocity to it..what i am doing wrong?
Where did you import the model or did you do that?
good job
Thanks for this contribution
Hi, is it possible to do multiple pass of the heat source? What parameter should I change to make this?
very good. thANKS
my convergence graph trend is going upward, and drag is negative value what does it means ?
best video on ansys fluent
Excellent Man (Thanks!.)
这和真正的焊接分析不是一个概念，这样分析毫无意义
Hello, can i get your number?, i have some problem, i need your help, please.😢 I'm from indonesia
Thanks a lot, very helpful😅
Super informational video!!! Noticed that you calculated force in X-direction at the end and said that's the drag force, but it should be the force in Z-direction(according to your geometry) i believe
Brilliant! Thank you so much for this ❤.
Can this be used in turbulence cases?
This might be a stupid question. Does ansys fluent show how ship trim (bow lifted) condition at different speed on the result (post processing). Or is it remain static. I ask this because i want to know ship trim condition at different speed so I'll run multiple simulation with different speed
Thats a good question
It can be possible, but need a lots of mesh deformation simulation.
@@AnsysTutor yeah it's possible I've done it and test it by myself. But the problem is when applying wall function especially y+=1, the orthogonal mesh getting worse especially on angled surface like keel, bilge, and near bow of the vessel. Thank you for replying thou, I've finished my undergraduate thesis even I'm not using ansys atleast your tutorial helped me understand CFD in general 🙏
how did we decide to choose the particular renolyds number ..... and what are x/c and y/c values next to Re
x/c and y/c are the emplacement on the airfoil at which Re has been calculated. In my studies I assume that Re doesn’t change, as long as i use my simulation to get lift and drag coefficient.
why heat soruce is perfectally circular
is it possible to do it with structured mesh? cause most tutorial show it with unstructured mesh
Bro we can do. But then your convergence time will very high and any ship type of complicated geometry mesh if we want to capture well we use tria. But yea you can use structure mesh also
@@souravkanthal2796 problem is when doing simulation of ship resistance in ansys we need to adjust inflation to y+=1 requirements and it messed up the orthogonal quality and lead to floating point exceptions error.
Hi, your videos are very helpful. Can you also make videos for the geometry and cfd simulation of the supersonic inlets of aircraft, used in ramjets and scramjets.
Amazing tutorial, would you make one with supersonic flow over a body? thank you
