'water turbine ....' simulation project by asmauos


#1

I created a new simulation project called 'water turbine ....':

water turbine


More of my public projects can be found here.

@dheiny hi, how are you ?
actually, i did new design for water turbine, and i fixed the problem.
could you check for me please ?

i will be thankful for you.

@lria Hello
sorry for annoying.
but i re-design the turbine.
could please simulate it for me :frowning:

i have to finish it today, because tomorrow is the submission. :’( :’(

thank you

@dheiny :frowning: could you check it please ?

@dheiny hi engineer.
could you help me ?

@Ali_Arafat Hi engineer,
I hope you feel good.
actually, i need help to simulate this design
i was trying for more than 70 day.

could you help me pleases ?

Hi @asmauos

I will take a look, But could you just explain a bit what you wish to do. For example the general problem , analysis type and flow conditions .

I will see then how I can help you out.

Best,
Ali

First of all, my design is about the water is flow inside the pipe and the turbine is rotating for energy recovery.
By assuming the inlet velocity approximately 3 m/s

Okay, I have just taken a quick look at your geometry model and there are a few issues you have to solve before you can start meshing and simulating.

1- The pipe ends are open: you need to close the ends with a face of some thickness to mesh the inside of the pipe.


For example see this project where the pipe ends are closed : https://www.simscale.com/projects/Ali_Arafat/water_flow_through_a_gate_valve

2- Next, Simplify and close the geometry at the turbine shaft part. see the images for detail.

.

3- Lastly, try to merge the blades with the shaft, as the small space in between would cause problems later on.

Once you have the New geometry model CFD ready, just upload it to the project and let me know.
I’ll take a look again to see if all is good.

Best,
Ali.
