Combustion model of a pyrolyzable polymer in a high-enthalpy flow with an radially applied electrostatic field

Abstract

Polymers combustion in high-enthalpy flows is realized in many power plants. This process is energetically favorable, but there are also significant problems, the main of which is the low combustion rate. An effective method to increase the condensed component regression rate is the imposition of an electrostatic field on the polymer, the polymer reaction layer, and the combustion zone. The paper proposes a physical and mathematical model of the electrostatic field influence on the PMMA combustion rate in high-enthalpy flows. The combustion rate values calculated within the described model coincide with the experimental results within the error.
