Fluid Material Properties

The Fluid material type is a parameter used with the BEGIN MATERIAL data block.

Syntax

Fluid Air		{
	FluidType =	"Newtonian"
	Density =	r
	SpecificHeat =	Cp(T)
	Conductivity =	K(T)
	Viscosity =	m (T) \| ho
	CoeffOfThermalExpansion =	β
	VolumetricHeatSource =	Qvol }

Comments

FluidType denotes the type of fluid and it is "Newtonian". Note that the non-Newtonian materials are classified as Polymer for Polymer Processing and Workpiece for Metal Extrusion. The specific heat, thermal conductivity, and viscosity can be input as functions of temperature.

Fluid Material Properties Data Types

The following table contains descriptions of data types for fluid material properties:

Variable Name	Value Type	Remarks
FluidType	String in quotes	"Newtonian" = Newtonian;
Density	Real (Constant)	Density of the fluid
SpecificHeat	Real (Constant/Function of Temp.)	Function can be a TABLE1 or EXPRESSION
Conductivity	Real (Constant/Function of Temp.)	Function can be a TABLE1 or EXPRESSION
Viscosity	Real (Constant/Function of Temp.)	TABLE1 or EXPRESSIONare used only for Newtonian fluid. For non-Newtonian fluids the viscosity is computed using the model specific expressions.
CoeffOfThermalExpansion	Real (Constant)	Thermal expansion coeff.
VolumetricHeatSource	Real(Constant)	Value per unit volume.
