Project Squid. Unsteady One-Dimensional Flows with Heat Addition or Entropy Gradients

Abstract

Nonlinear differential equations of the Rieman type are derived to solve problems involving propagation of one-dimensional waves in flows in tubes of slowly varying cross section with heat addition or entropy variation. Transient flows arising when heat is added to a section of an initially isentropic flow in a tube are calculated. The results afford an insight into gas dynamic aspects of intermittent heat addition in a flowing gas and into the apparently anomalous behavior at sonic velocity of steady gas flows with heat addition.
