Use the Heat Transfer node to define the tangential velocity, density, dynamic viscosity, and heat convection and conduction properties.
The default Density ρ (SI unit: kg/m
3) uses the value
From material. For
User defined enter a different value or expression.
The default Dynamic viscosity μ (SI unit: Pa·s) uses the value
From material and describes the relationship between the shear rate and the shear stresses in a fluid. Intuitively, water and air have a low viscosity, and substances often described as thick (such as oil) have a higher viscosity.
The default Density ρ (SI unit: kg/m
3),
Dynamic viscosity μ (SI unit: Pa·s),
Heat capacity at constant pressure Cp (SI unit: J/(kg·K)),
Ratio of specific heats γ (dimensionless), and
Thermal conductivity k (SI unit: W/(m·K)) all use values
From material. For
User defined enter different values or expressions.
