An Analysis of Non-Constant Area Heat Addition Due to Combustion in a Supersonic Air-Stream.
Abstract
A condition critical to the occurrence of ignition in a ducted supersonic stream has been proposed. By utilizing this concept as a further boundary condition, a new approach to the solution of the gas dynamic equations relevant to combustion in a ducted supersonic stream has been made. This approach involves the duct characteristic with which to describe the combustion process. For engineering, a duct law has been found to satisfy the system of equations; it can be considered to be the additional equation required to close the problem. The above temperature-area relationship, which established the critical Mach number at which thermal choking occurs as unity, can be used as an alternative to the Crocco pressure-area relationship which predicts a non-unity critical Mach number.
