摘要

A Bi-Conjugate Gradient method (Bi-CGSTAB) is studied and tested for solid combustion in which the gas and solid phases are coupled by a set of conditions describing mass, momentum and heat transport across the interface. The conjugate gradient method is found to yield robust solutions for pressure and lead to accurate prediction of the burning rates along the length of the polymer plate. Specifically, the conjugate gradient method is significantly simpler with faster convergence that the multi-grid method (MOlD) for a given accuracy in the predicted burning rates.
