火炕是我国北方农村地区应用最广泛的建筑采暖方式,由于火炕搭建依靠农民经验,缺乏理论指导,常出现炕面温度过高等现象。因此,为有效改善炕体性能,需深入研究火炕系统传热流动模型。本文在总结火炕模型的建立途径的基础上,从微观与宏观的角度得到火炕传热流动模型包括计算流体力学模型和热平衡模型。分别介绍了各个模型的理论基础、模型假设、参数选取以及模型验证的研究现状,总结了目前存在问题并提出了下一步研究方向。 Ondang is the most widely used method of building heating in the northern rural areas of our country. Due to the construction of the kang relying on the experience of peasants and the lack of theoretical guidance, it often appears that the temperature of the kang surface is too high. Therefore, in order to effectively improve the kang body performance, in-depth study of kong heat transfer flow system. On the basis of summarizing the way of building kang kang model, this paper obtains the heat transfer flow model of kong including the computational fluid dynamics model and heat balance model from the micro and macro perspectives. The theoretical basis, model assumptions, parameter selection and model verification of each model are introduced respectively. The current problems are summarized and the next research directions are proposed.
