Setup (Physics)
Update the Project and Open FLUENT
Before we open FLUENT, we need to update the project the import the mesh into FLUENT. To do this, click Update Project . When the project updates, double click Setup to open FLUENT.
Initial Settings
Before FLUENT launches, we will be prompted to set some options. In Options check the box next to Double Precision. If you have a dual processor, you can set the option under Processing Options to Parallel, and change the Number of Processes to 2
.
Once the options are set, click OK.
Problem Setup - General
Now, FLUENT should open. We will begin setting up some options for the solver. In the left hand window (in what I will call the Outline window), under Problem Setup, select General. The only option we need to change here will address the fact that pipe domain we created is axisymmetric. Under 2D Space, click the radio box next to Axisymmetric.
Models
In the outline window, click Models. We will need to utilize the energy equation in order to solve for the temperature. Under Models highligh Energy - Off and click Edit.... Now, the Energy window will launch. Check the box next to Energy Equation and hit OK.
Materials
In the Outline window, highlight Materials. In the Materials window, highlight Fluid, and click Create/Edit.... this will launch the Create/Edit Materials window; here we can specify the properties of the fluid. Set the Density to 1.2
, the Specific Heat to 1000
, the Thermal Conductivity to .02
, and the Viscosity to 1.8e-5
.
