More Book Details

Description of the Book:

A recently developed subroutine package for the integration of systems of ordinary differential equations by implicit methods is tested on a variety of gas dynamic problems. These problems include one-dimensional unsteady gas flow and two and three-dimensional parabolic (steady) Navier-Stokes problems. The governing partial differential equations were converted to systems of ordinary differential equations using either finite differences or finite elements, and then integrated by the implicit integration package. Included among the examples is a realistic steady laser cavity flow problem. (Author
