Numerical Study of Upstream Radiative Heating in 1-D Detonations

Abstract

The attainment of high flame temperatures in detonations renders the resultant heat flux during the process worthy of consideration. The focus of the present study was on the radiative component of this heat flux. Through the usage of high resolution grids in the region downstream of the embedded shock wave, and the evaluation of chemical properties of the fluid through CHEMKIN, the radiative parameters affecting the region upstream of the shock wave were determined. Numerical integration of the governing equations for steady, one dimensional flow was attained using the Livermore Solver for Ordinary Differential Equations (LSODE). Commonly assumed constant temperature profile in the upstream region displayed a non-linear behavior after considering upstream heating, qualitatively similar to well established results in detonation waves. These results quantitatively describe the effect of heating of fresh reactants in detonations, serving as a tool for consideration in computations involving detonations, such as in pulse detonation. © 2013 by K.
