Thermal Properties for Fluid Materials

Note: For fluid materials, Thermal Conductivity, Specific Heat, Thermal Diffusivity, and Dynamic Viscosity can be assigned a Thermal Modifier to define a temperature dependency. See Specifying Thermal Modifiers for more information.

The thermal properties a material has is determined by the Thermal Material Type selection. When the material is a Fluid, the following properties must be set:

Thermal Conductivity is the thermal conductivity of the material.
Mass Density is the density of the material.
Specific Heat is the specific heat capacity of the material.
Thermal Expansion Coefficient is the volumetric expansion coefficient of the material.
Thermal Diffusivity is the diffusivity of the fluid.
Molecular Mass is the molecular weight of the fluid.
Dynamic Viscosity is dynamic viscosity of the fluid.

Note: If you use the ideal gas law and you have created a new fluid material, make sure that you specify the correct molecular weight for the new material.

Note: If a thermal modifier is applied to mass density with ideal gas law enabled, the thermal modifier is used in the simulation.
