Defining the Solid Boundary and Initial Conditions
Set boundary conditions for the solid region and the initial temperature.
For the independent simulation of the chimney, set the outer boundary to lose heat by convection, and the inner wall boundary to maintain a constant temperature. The OuterSurf boundary is exposed to air at 283 K with a heat transfer coefficient of 0.12 W/m^2-K.
- Expand the node.
To apply the convection boundary:
-
Edit the
OuterSurf node, and set the following properties:
Node Property Setting Physics Conditions Thermal Specification
Condition Convection Physics Values Ambient Temperature
Value 283.0 K Heat Transfer Coefficient
Value 0.12 W/m^2-K
To apply the constant temperature boundary:
-
Edit the
InnerSurf node, and set the following properties:
Node Property Setting Physics Conditions Thermal Specification
Condition Temperature Physics Values Static Temperature
Value 380.0 K Leave the Default boundary as adiabatic.
- Select the 283.0 K. node and set Value to
