MULTIPLICITY ANALYSIS OF THE 2-D MODEL OF THE CATALYTIC POROUS WALL REACTOR WITH AXIAL-FLOW

Numerical bifurcation techniques were analyzed and developed for study ing the multiplicity of the 2-D model of the catalytic porous wall rea ctor with axial flow. The continuation technique is based on the gener alized inverse iteration with Rayleigh quotient. The using of the mult igrid and the conjugate gradient for nonsymmetric systems methods in t he continuation algorithm is tested. The choice of the preconditioner is also analysed for the conjugate gradient methods. The numerical per formances of the different algorithms used are investigated and compar ed. The key parameter of the investigation is the reaction parameter. The effect of the other parameters on the bifurcation behaviour is bri efly analyzed.
