摘要
为了研究由四棱柱和其内部多支水平圆管所构成的封闭腔体的内部自然对流热交换情况,在有限体积法的基础上采用层流模型,对4种水平圆管数量与结构不同的封闭腔体内部温度场和流场进行了数值模拟,并初步研究了封闭腔体内换热管周围温度场分布及其均匀性。
To investigate natural convection heat tranger in an enclosed space between an outer quadrangular and some inner horizon cylinders, the flow and temperature fields in four kinds of enclosed spaces composed of different numbers and structures of cylinders are numerically simulated, based on finite volume method and laminar model. Distribution of temperature field and uniformity around the heat exchanger in the enclosed space are introduced.
