Week 6: Conjugate Heat Transfer Simulation
Week 6: Conjugate Heat Transfer Simulation
ANSWERS
As the Reynolds Number is 7000, on further calculation, we got the velocity is 2.58 m/s. So we use velocity = 2.6m/s for the future calculation.
CASE 1
As for the first case, we use Grid size = 0.004mm and Super cycle stage interval size = 0.01.
Here
Today we are going to solve a basic problem of a Conjugate heat transfer problem by using a basic created geometry.
This is the geometry which we are dealing with. This is a basic 3D geometry of a pipe with thickness, and the hot fluid (air) is flowing through it.
First, we need to create a geometry as per the dimensions.
Then, we need to create another cylinder over the previously created one.
Now, we delete the side profiles to look as a hollow cylinder.
The final geometry
CASE SETUP
Gas Simulation is set to default
Selecting material for the solid and fluid component
Run Parameters - Default
Simulation time parameter is set according to
Boundary Condition, Solid Outer Wall
Inlet
Outlet
Interference
Regions and Initialization, create two regions, Fluid Region and Solid Region.
Super Cycle modeling is set according to this
Grid Scaling, mesh size is set to 0.004mm
Enable y+ for the output files
Out put files is set to as follows
Now, we start to run the simulation using Cygwin.
The simulation ran successfully
