摘要
根据浮空器的特点,分析了其载荷舱内的基本传热途径,建立了自然对流与辐射耦合传热问题的三维稳态数学模型。运用CFD软件进行数值模拟,得到了舱内气体的温度和载荷的表面温度。为载荷舱热特性的进一步研究奠定了基础。
Based on the properties of aerostats,the fundamental heat transfer patterns of load cabins were analyzed,and a three dimensional steady mathematical model of a conjugate heat transfer issue concerning natural convection and radiation was established,then the temperatures of air and wall surfaces were obtained by using a CFD software.A foundation is presented for the further study of thermal characteristics and of load cabins.
