Ok, sorry I understand. I assumed that the graph (figure -1) shows the velocity, of the cylinder's front surface, so cylinder could move forward in a highly viscous environment (low reynolds...

thanks for your insights

Please see the attached prepin file.

Thanks for your support.

Please remember that i am a beginner and tried to implement what i learnt through gmo sphere tutorial.

Hi

It is actually a nanoscale motor. which drives the cylinder through spinning. when it spins, under low reynolds number environment, due to viscous force it goes forward like a screw. so no...

Thanks a lot. I checked the theory, due to high viscous force there is accumulated azimuthal velocity driving rod in forward direction given by (pls see the attached picture)

Any idea why it is...

Spinning cylinder in viscous liquid - a serious doubt

I have made a cylinder rotating about its axis in a highly viscous liquid (to mimic low reynolds no). according to theory,the cylinder has to move axially forward but in my CFD simulation it goes...
