Hi all. I’m solving a centrifugal pump. I transfer the fluid velocity profile (magnitude velocity) from the end of the wheel to the beginning (I simulate that I have two wheels).<\/div>\n
Here’s how I do it:<\/div>\n
<\/div>\n
1.I write to the out_wheel file and solve the problem.<\/div>\n
2.I am reading from the file out_wheel. And I already assign the file out_wheel1 to recording (so that I can then read out_wheel1, etc.).<\/div>\n
3. The entrance and exit from the wheel look like this:<\/div>\n
<\/div>\n
4.The input and output surfaces from the wheel are included in the interface section. So to enter the wheels, I had to change the type to INLET VELOCITY.<\/div>\n
There I select the magnitude velocity (it was connected from a readable file).<\/div>\n
<\/div>\n
5. I start a new calculation and see that the pressure has not increased much. Previously, the pressure was 10, now it is 13. At the same time, the flow rate at the pump inlet dropped from 3.7 to 2.1. The outlet pressure increased by only 0.3 atm.<\/div>\n
The pressure should have increased to 20 and the pressure would have increased by 1 atm.<\/div>\n
Maybe I did something wrong?<\/div>\n
Thank you.<\/div>\n","protected":false},"template":"","class_list":["post-349206","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
