摘要

提出方型石油化工管式炉中辐射室的三维流动和传热的数学模型.对某焦化炉计算的结果与实测数据进行了初步比较并作出讨论.

Abstract

A three-dimensional mathematical model has been developed for predicting the transport of mass

energy and momentum in the combustion chamber of a rectangular multi-burner. The turbulence two-equation model and Monte-Carlo method ard used for simulating the turbulence flow and radiative heat transfer

and a combustion model of turbulent diffusion flame is considered. The governing differential equations which are composed of velocity

mixture fraction

fuel concentration

stagnant enthalpy

turbulent kinetic energy and turbulent energy dissipation are solved by tri-diagonal matrix algorithm. The distributions of the temperature of fuel gas and the heat flux of wall are predicted in a coking furnace. A comparison between the calculated and measured results shows that the prediction is successful.
