Transonic Small-Disturbance Theory for Dusty Gases.
Abstract
The correction to transonic small-disturbance theory induced by the addition of contaminant particles (e.g., dust) to the gas is analyzed. Two-phase flow equations governing the particles and inviscid fluid are used. The dusty gas version, a particular limit of the flow equations in which the volumetric concentration of the particles is small, but the mass concentrations of particles and fluid are comparable, is employed. In this setting, a model in which the gas and particles may be viewed as an equivalent gas with modified properties, is derived. This generalized gas model behaves like a normal gas with a modified value (the ratio of specific heats). Using this model, a simple method of analyzing transonic small-disturbance theory, by employing a modified transonic similarity parameter, is used to account for the effect of the dust. (Author)
