Thank you! I'm a beginner and I found this very very helpful :)

[@MechTechSimulations]

Glad it was helpful! Subscribe and share our videos to your friends.

Hi! Great tutorial. Can you explain the choosing of outlet boundary conditions in this case (or why you didn’t assign any value to them)?

[@MechTechSimulations]

By default, in pressure outlet, the (gauge) pressure will be zero. As i want to leave that as zero gauge pressure, i didn't changed it.

Can you do a video for flow through nozzle and calculate the throw of water jet?

[@MechTechSimulations]

I will do it for sure. Sorry for the delayed response. If you still need help with that, please reach me through [e-mail]

[@sagarchaudhari8779]

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 hoping for your favorable response.

plz how do i put the direction of the arrow on the geometry for indicated the moving wall

[@MechTechSimulations]

Hello @laouira, there is nothing to move in this tutorial. If you are asking about something else, let me answer your question. If you are expecting to move a wall, enter into the boundary condition and select either translation or rotation of the selected wall. Give the required speed of motion (your case will now become transient). Refer my video kzbin.info/www/bejne/nZTPgWCrr5WbisU for further details on moving wall.

What is value of 3.5e+003

[@laouirahanane1237]

I worked on a trapezoidal geometry of 2D and I found the results very well now I wanted to turn to work 3D without repeating all the work done to make the symmetry a ansys how ? God bless u

[@MechTechSimulations]

Up to my knowledge, you have to repeat the analysis from design modeller itself, as you would have created a plane for 2D analysis. For 3D analysis, the geometry itself to be changed [Extrude].

HELP, im trying to select 1 edge but it automatically select all the edges, how do I fix this??????

[@MechTechSimulations]

In what program you are selecting the edge? Design modeller?

[@flacourtia6486]

Maybe you're selecting it using body selection instead edges selection?

[@mohamedmosad2107]

good tutorial, why you select k epsilon viscous , however the velocity is small ?

[@MechTechSimulations]

I haven't selected in any basis. I just made it for a simple tutorial. It should be selected based on the reynold's number

[@rahulspicy4u]

Can I find equal fluid distribution at two outlets from one inlet? How can I be sure that the fluid is distributed EQUALLY in branches of several pipes? Thank you!

[@MechTechSimulations]

Yes Divyesh. In this case, water is unevenly distributed because of the following reasons: 1. Diameter of the outlet pipes are different 2. The angle made between the outlet pipes and the inlet pipe are different 3. Due to the acceleration due to gravity, the lowermost pipe discharges more water (however gravity is not considered in this tutorial) If you expect equal distribution in all the outlets, you may play with the branching angles, diameters or some obstruction etc., to achieve it.

[@rahulspicy4u]

That makes sense. Thank you so much for your reply. Really appreciate for sharing this video. Because I am doing something similar to this. At some extent, this video helped. So, really thank you! However, I am having difficulty to figure out whether I could have equal distribution flow or not in my Manifold design. It has one inlet and two outlets. But I am confused with respect to my boundary conditions. I tell you why? At inlet (single pipe) - velocity - 26 m/s and at outlet 1 and at outlet 2 - outflow = 1 for both. I thought my result was perfect with this boundary condition. Because it shows that the flow rate; at both outlet 1 and 2 is same. That means I have equal distribution in my manifold design. But when I changed boundary condition from Outflow to Pressure outlet (Pressure = 0) then I have got different result. Results show that the flow rate values are different at both outlets 1 and 2. :( Now, I don't know, which one I should follow? If you can help me, it would be really helpful. Thank you once again!

[@rahulspicy4u]

Just to let you know, in my case, Inlet dia. is 210mm and Outlet 1 & 2 dia. is 160mm (So both outlets dia are same size).Your response will be highly appreciated!

[@MechTechSimulations]

Is both the outlets are symmetric? I'm not sure about the outlet boundary type, generally if the outlet pressure is unknown, people prefer outflow boundary. Further, I may share my best suggestion if you could share the snapshot of the geometry for my better understanding. (e-mail: [e-mail]

[@rahulspicy4u]

I am sorry. I couldn't respond you quickly. I was so stuck with this Analysis - have no clue about my doubt. Well, answer to you question: Yes!! Outlets are symmetric. In my case, I want to find whether the distribution is happening equally or not? Pressure is unknown at OUTLET. When I checked ANSYS Fluent user manual, it says; usually, we need to use outflow in Boundary Condition for 2 or more equal outlets. Thanks for your support. I am going to send you details today on your email id. Thank you so much once again!

How does one simulate mass transport using ANSYS, any idea?

[@MechTechSimulations]

I am not clear with your question. Sorry!

[@tochukwuapugo-nwosu2289]

@@MechTechSimulations OK, what tool in ANSYS do you use in ANSYS to simulate mass transfer processes?

[@MechTechSimulations]

You could use Ansys FLUENT or Ansys CFX

[@anithagopinath5]

Sir, How can I provide depth of flow in boundary condition? Iam modeling an open channel with cylindrical rods(3dimensional) depth of water 10.25 cm Discharge 2.77l/s Velocity 8.94cm/s

[@MechTechSimulations]

Generally in this case a fully developed flow is considered. If you want to study open channel, would you need to consider the interaction between air and water? If so, you have to go for multiphase analysis. In my knowledge, we cannot provide the depth of flow without multiphase flow analysis.
