The three-dimensional flow and heat transfer distribution in a radiant cooling chamber of a waste heat boiler with a doubly-flowed wall are numerically simulated. The flow is simulated by the k-ε equation and the radiation is calculated by the Monte Carlo method. The geometric space uses multiple structures to reduce the computer memory waste. The body coordinate system is used to describe the complex geometric boundaries. The grid system uses staggered grids. The SIMPLE algorithm is used to solve the equations. The three-dimensional flow and heat transfer results of radiation cooling chamber of waste heat boiler are given. This study provides a theoretical basis for studying the indoor flow of radiation cooling of waste heat boiler, which provides detailed data and effective measures for the design of waste heat boiler and energy saving.
