Thermal Coupling — Convection dialog box

Use this dialog box to set options for the Thermal Coupling — Convection simulation object for the Simcenter 3D Thermal/Flow, Space Systems Thermal, Electronic Systems Cooling, and Multiphysics solvers.

Type
Convection Coupling Models convective couplings between the fluid ducts and the convecting region using the specified heat transfer coefficient. For more information, see Convection Coupling options.
Forced Convection Coupling Models forced convective couplings computed using standard correlations for forced convection in a 1D flow system with a developing boundary layer, or a fully developed boundary layer. For more information, see Forced Convection Coupling options.
Free Convection Coupling Models free convective couplings computed using standard correlations for free convection from regular objects. For more information, see Free Convection Coupling options.
Across Gap Convection Coupling Models heat transfer between two parallel surfaces (regions) where a convecting fluid is the medium of heat exchange. For more information, see Across Gap Convection Coupling options.
Duct Node Convection Coupling Models convection heat transfer between fluid duct nodes and the duct wall. For more information, see Duct Node Convection Coupling options.
