Abstract

Relevance The use of ozone-catalytic reactions is a promising method for purifying water, air and exhaust gases. They can be used, among other things, to solve the problem of cold starting of a car engine, allowing for the effective neutralization of toxic impurities even at low temperatures. Optimization of an ozone-catalytic device (according to the criterion of minimizing specific energy costs) requires the development of a mathematical model that takes into account the mutual influence of numerous parameters of physical processes occurring in the channels of the catalytic unit. A large number of mutually influencing parameters actualizes the use of iterative algorithms for the numerical solution of a system of equations of a mathematical model. Aim of research The aim of this article is to develop a mathematical model of the physical processes occurring in the ozonizer, and to create on its basis an iterative method that is possible to determine the change in temperature, pressure and composition of the gas mixture as it moves through the channels of the ozonizer of a honeycomb structure, taking into account the mutual influence of these parameters to each other and to the power of the barrier discharge. Research objects Ozone catalytic device. Research methods Mathematical modeling of physical processes. Results To solve the system of equations describing the physical processes in the ozone-catalytic device, an iterative algorithm was developed to determine the spatial distribution of parameters (temperature, pressure, ozone concentration) in the channels of the catalytic unit of the honeycomb structure.
