 Title:
A SCHEME TO SOLVE NON-LINEAR CONDUCTION PHENOMENA BASED ON A SEQUENCE OF LINEAR PROBLEMS
 
Summary :
THE PRESENT WORK PROPOSES A SCHEME TO SOLVE NON LINEAR HEAT CONDUCTION PROBLEMS BASED ON A SEQUENCE OF LINEAR PROBLEMS. AN OPAQUE THREE-DIMENSIONAL PLATE WITH A NON-LINEAR TEMPERATURE-DEPENDENT SOURCE DOMINATING THE CONDUCTIVE OPERATOR IS STUDIED BY EMPLOYING A CONVERGENT SEQUENCE OF LINEAR PROBLEMS WHOSE SIMULATION TECHNIQUE, BASED ON A FINITE ELEMENT METHODOLOGY, IS KNOWN. SINCE THE CLASSICAL GALERKIN METHOD PRESENTS INSTABILITIES WHEN SUBJECTED TO VERY HIGH SOURCE-DOMINATED REGIMEN, A GRADIENT-GALERKIN/LEAST-SQUARES FORMULATION IS PRESENTED FOR A LINEAR PROBLEM - AN ELEMENT OF THE CONVERGENT SEQUENCE.
