Abstract:

This paper outlines a generalised boundary solution method for solving flow at boundaries of ID duct models. It is adaptable to duct-duct connections and duct-volume connections with subsonic, choked and supersonic flows. It is fully nonhomentropic (accounting for friction, and temperature and property variations). The generalised approach aids in reducing code complexity for the approximately 30 distinct flow types that can exist at the boundaries of I D ducts. Assumptions are described and numerical methods outlined. The so lution requires solution of a number of non-linear simultaneous equations which is accomplished with the Newton-Raphson method. Sample results for a converging flow compared to experimental date are given.
