摘要
以农村住宅采暖房间为研究对象,分析火炕和散热器采暖方式对其室内热环境的影响。室内空气自然对流采用Boussinesq假设,辐射传输方程采用净热流法,湍流采用k-ε模型描述,建立采暖房间室内热环境数学模型,利用Fluent对火炕及散热器采暖的室内热环境进行数值模拟。
By taking the heating room of rural residence as the research object,the effect of heated kang and radiator heating system on indoor thermal environment is analyzed.The boussinesq assumption is used in natural convection of indoor air.The net heat flux method is adopted in radiative transfer equation.Turbulence is described by using k-εmodel.The mathematical model of indoor thermal environment in heating room is established.The numerical simulation of indoor thermal environment by adopting heated kang and radiator heating system is done by using of Fluent software.
