Abstract:

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 hydrogenair combustion rather than methaneair. 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.
