Numerical Simulation of Heat Transfer and Gas Flow Characteristics in Honeycomb Ceramics

摘要

Honeycomb ceramics is the key component of the thermal flow-reversal reactor, which is for oxidation of coal mine ventilation air methane. In this paper, numerical simulation method was used to study the honeycomb ceramics' heat transfer process, and the effects of temperature difference and hole side length on heat transfer and the resistance losses were investigated. The calculating results show that the temperature difference between the gas and honeycomb ceramics is larger, then the heat transfer effect is better, and the resistance loss is bigger. In the situation other parameters are the same, then the hole side length is longer, the heat transfer efficiency is lower, and the resistance loss is smaller.
