Hello,
I have a circular tube that is approximately 150 mm long and the last 15 mm of the tube (the tip) will deflect 30 degrees to -30 degrees. I have a velocity inlet and a pressure outlet. I want to simulate a fluid flowing through the bending tip. The tip motion is to be defined from an external device and is not due to fluid forces. I would like to examine the effect of tip angle on the exit flow rate as well as examine the exit flow velocity distribution. I have attached a picture detailing how the tip will displace during one oscillation. The red dotted lines indicate where the bending will take place. I believe I would need to define a moving mesh with a prescribed deformation for the bending region. Any suggestions or advice on how I may go about this would be greatly appreciated. I am using COMSOL 5.3a.
Regards, Will McKinney
