摘要:
开展了利用黑体凸起结构强化钢厂热锻压炉炉膛辐射传热的数值研究.采用Gambit软件设计出模拟炉膛段,利用Fluent软件对炉膛段内辐射传热过程进行了耦合数值模拟,获得了炉膛内烟气的流场、温度场以及锻钢表面辐射热流密度.分析了炉壁表面黑度以及不同凸起结构对辐射传热效果的影响规律.结果表明,提高炉膛内壁黑度以及加装凸起辐射元件对炉膛内辐射传热有显著的强化作用.通过Gambit模拟改变辐射元件的尺寸、形状,得到最佳的安装方案可以提高炉膛内烟气15%的辐射传热效率.
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.
