1、 blackbody, where all incident radiation is absorbed by the surface. Heat Transfer and Thermal-Stress Analysis with ABAQUS L4.19 Copyright 2006 ABAQUS, Inc. ABAQUS Usage Emissivities may depend on temperature or any number (N) of predefined field variables. The value of these field variables is cont
2、rolled by the FIELD option. *EMISSIVITY, DEPENDENCIES=n Emissivity, Temperature, Field Var 1, Field Var 2, Use as many data lines as needed to define the dependence of emissivity on temperature and field variables. Further nonlinearity is introduced by defining emissivity as a function of temperatur
3、e. However, this seldom has any significant effect on the computational effort needed to solve a problem. The emissivity dependencies are handled explicitly in ABAQUS/Standard. The MXDEM parameter in the HEAT TRANSFER option is used to control the time incrementation when emissivity varies by contro
4、lling the change in emissivity per increment. Heat Transfer and Thermal-Stress Analysis with ABAQUS L4.20 Copyright 2006 ABAQUS, Inc. ABAQUS Usage Physical constants The PHYSICAL CONSTANTS, STEFAN BOLTZMANN option must be used to provide the Stefan-Boltzmann constant in consistent units (e.g., in SI
5、 units 5.67108 W/m2K4). The ABSOLUTE ZERO parameter can be used with this option to provide the value of absolute zero in the temperature scale being used. ABAQUS/Standard uses this value to convert the model temperatures automatically to absolute values for the cavity radiation calculations. Heat T

The syntax is *CAVITY DEFINITION, NAME=zzz, AMBIENT TEMP=value List of surface names that compose this cavi
7、ty The NAME of the cavity is used to control radiation and viewfactor calculations in the RADIATION VIEWFACTOR option. It can also be used to request printout specific to that cavity in the RADIATION OUTPUT, RADIATION PRINT, RADIATION FILE, and VIEWFACTOR OUTPUT options. Heat Transfer and Thermal-St
8、ress Analysis with ABAQUS L4.22 Copyright 2006 ABAQUS, Inc. ABAQUS Usage A model can have any number of cavity definitions. A cavity can be open or fully enclosed by surfaces: an open cavity implies that there is radiant heat exchange to ambient. The reference temperature of the ambient is defined w
9、ith the AMBIENT TEMP parameter. Heat Transfer and Thermal-Stress Analysis with ABAQUS L4.23 Copyright 2006 ABAQUS, Inc. ABAQUS Usage The sum of the viewfactors for each facet in a closed cavity should be one. The sum of the viewfactors for a facet in an open cavity may be less than one. The differen

In cases where there is more than one opening in the cavity looking out on different external media (at different ambient temperatures): The openings must be closed with dummy
11、heat transfer elements that have prescribed temperatures and applied radiation surfaces with emissivities of 1.0 (blackbodies). Heat Transfer and Thermal-Stress Analysis with ABAQUS L4.24 Copyright 2006 ABAQUS, Inc. ABAQUS Usage Based on the cavity definition, cavity radiation elements are created i
12、nternally by ABAQUS/Standard. These elements may generate large matrices because they couple the temperature degrees of freedom of every node on the cavity surface. This can increase the wavefront significantly for models with large, multifaceted cavities. The Jacobian matrix for these elements, nee
