Abstract:
This paper carries out numerical study on the enhancement of radiation heat transfer in forging furnace by raised radiation elements. The simulated furnace is designed by Gambit. The coupled heat transfer process in the furnace is numerically simulated by Fluent，from which details information of the flue gas temperature field and the radiation heat flux density in the furnace are obtained. The effects of furnace wall emissivity and different shapes of raised radiation elements on radiation heat transfer in forging furnace are analyzed. The results show that，the radiation heat transfer efficiency can be enhanced by increasing the furnace wall emissivity and installing raised radiation elements with high emissivity. By changing the size and shapes of the radiation elements，15% increase of radiation heat transfer efficiency can be achieved.
