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; |
| Desnity | 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 |
| Viscoscity | Real (Constant/Function of Temp.) | TABLE1 or EXPRESSION are 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. |
