室内空气的热舒适性和浮力诱导运动由建筑构件中不同类型的传热和蓄热的相互作用决定。热传递包括辐射、对流和传导（在空气和建筑结构内）的能量传输。对于高空间，空气浮力的驱动力变得更加明显。因此，在大型外壳的设计中，这些相互作用的正确建模变得更加关键。特别是在中庭，由于大面积的玻璃窗，太阳和红外辐射非常重要。 空气流动、表面到表面辐射和建筑动力学的边界条件与可能随时间和空间变化的表面温度有关。提出了计算流体力学与热动力学和辐射直接耦合的数值方法，并在IEA附件26的案例研究大楼中进行了演示。关键词:1995年，计算，热流，辐射，对流，中庭，热惯性，热舒适性，浮力，气流，房间，储能，建筑，部件，设计，大型，太阳辐射，红外辐射，玻璃，表面温度，案例研究，算法: 研讨会，ASHRAE Trans。1995年，第101卷，第2部分

The thermal comfort and buoyancy-induced motion of air in a room are determined by the interaction of different types of heat transfer and of thermal storage in building components. Heat transfer includes energy transport by radiation, convection, and conduction (within air and the building fabric). The driving forces of buoyancy of air become more pronounced for tall spaces. therefore, proper modelling of these interactions becomes more critical in the design of large enclosures. In atria, in particular, solar and infrared radiation are important because of large-area glazing. The boundary conditions for air flow, surface-to-surface radiation, and building dynamics are linked by surface temperatures that may vary in time and space. Numerical methods for the direct coupling of computational fluid dynamics with thermal dynamics and radiation are proposed and demonstrated at a case study building of IEA Annex 26.KEYWORDS: year 1995, calculating, heat flow, radiation, convection, atria, thermal inertia, thermal comfort, buoyancy, air flow, rooms, energy storage, buildings, components, designing, large, solar radiation, infrared radiation, glazing, surface temperature, case studies, algorithms
