摘要: 对气流横向冲刷管束换热这种比较复杂的流动形式,推导出了气流横向冲刷管束换热时的传热努塞尔数与场参数的关系表达式,用数值模拟的方法对场协同原理进行了分析与验证.结果表明,场协同原理同样适用于这种形式比较复杂的流动与换热.同时用场协同原理解释了管排方式和管间距对换热的影响,发现随着速度场与热流场协同作用的不同,换热随管排方式和管间距的改变也有所不同.

关键词: 传热, 管束, 场协同原理, 数值模拟

Abstract:

The correlation equation between the Nusseh number of heat transfer and the field parameters is derived when gas flow through tube bundles in transverse direction,and the Field Coordination Principle is analyzed and validated by numerical simulation.The resuhs show that the Field Co rdination Principle can also be applied to the complex flow and heat transfer of tube bundles.Moreover,the influences of arrangement mode and tube pitch on the heat transfer are explained by the Field Coordination Principle.It is found that the heat transfer performance varies with the arangement mode and the tube pitch because of the coordination between the velocity field and the heat flow field.
