Hi Aravind,

At a high velocity of 14m/s, the flow separates at an angle less than 90 degrees subtended along the flow axis. Fomula for the same can be found from any Fluid mechanics text. That...

When you say 'start from zero', do you mean to say you are initializing the fluid domain with zero velocity. There is nothing wrong with it but it will take a lot of time. Initialize with your...

Hi,

Thank you for all the advice. I am getting the Street and the expected Drag coefficient. But what I do not understand is the flow time. For a Re=1500 (v=0.01 m/s) the time step is 1.875 and I...

Sir,

I had followed your advise with respect to the model I was working on (Re=1500). But since I did not get the expected drag, I reduced my flow speed to get Re=100 (Laminar). There are numerous...

Hi,

Can any one please help me with this drag coefficient!!! Just to make things easier I am running the simulation at Re=100 which is completely laminar. I should be getting a Cd somewhere close...

Hi again,

I have tried out the suggestions you had suggested and yes I am getting a Vortex street. The drag coefficient comes to around 0.4 which does not tally for this Reynolds number.

I...

Hello Sir,

This simulation is for my 3rd year project in Fluid Dynamics. Actually I am supposed to determine the drag force for a 3d cylinder under similar conditions. But to start off I have...

Flow over circular cylinder

Hi,

I am a beginner to Fluent user trying to model the flow past a circular cylinder at Re=1500 (v=0.01 m/s, diameter=0.15m, fluid - water). The boundary conditions I have put in for the...
