Simplified Method for Solving Problems Involving Chemically Reacting One-Dimensional Flow

摘要

A simplified technique for solving 'stiff' differential equations common to chemically reacting quasi-one-dimensional inviscid nonequilibrium flow analyses is presented. The method is basically that used by Degroat and Abbett with the generalization made to allow for a prescribed area distribution rather than the constant pressure (and hence constant velocity) process assumed by them. In addition, the equations are written for hydrogen/air combustion rather than methane/air. The advantage of the technique is that the chemical kinetic calculations can be solved quickly without loss of accuracy, and thus can be regelated to the status of a subroutine in complicated fluid-dynamic problems.
