Flow and thermal models

These pages explain the flow, material, and heat-transfer models used within the computational domain.

• Material domains and properties explains fluid material assignment, connected thermal regions, and the properties required by fluids and solids.
• Conducting and insulating domains explains which regions participate in the temperature solve.
• Conducting surfaces explains the thermal resistance of thin layers and their effects on existing thermal boundaries.
• Isolated thermal regions and power balance explains which heat-transfer paths connect regions and when prescribed heating and cooling must balance.
• Turbulence inlet conditions and wall treatment explains how inlet inputs become tke and sdr conditions and which wall functions Vanellus applies.
• Boussinesq buoyancy and reference temperature explains temperature-driven flow and the model reference temperature.
• Compact thermal models compares two-resistor and STAR networks and explains package-face heat transfer.
