ANALYSIS OF THE SENSITIVE PARAMETERS IN THE THERMAL RADIATIVE PROPERTIES IDENTIFICATION
|
| |
|
Summary :
|
|
THIS PAPER IS FOCUSED ON IDENTIFICATION ANALYSIS FOR THERMAL RADIATION PROPERTIES OF DISPERSED MEDIA WITH A HIGHLY FORWARD AND BACKWARD PEAKED SCATTERING. THE DIRECT MODEL IS BASED ON A DIFFERENTIAL DISCRETE ORDINATES METHOD FOR AN ONE-DIMENSIONAL PLANE SLAB WITH AZIMUTHAL SYMMETRY. AN INVERSE METHOD BASED ON THE GAUSS LINEARIZATION METHOD IS USED TO DETERMINE EACH OF THE UNKNOWNS. TO ASSURE THE CONVERGENCE OF THE INVERSE METHOD ONE UNDERRELAXATION IS PROPOSED.
KEY WORDS: THERMAL RADIATION, PARAMETER IDENTIFICATION, DISCRETE ORDINATES METHOD, RADIATIVE PROPERTIES.
