The heat dissipation assessment of radiator needs both drawdown flow curve and heat exchange flow curve.
散热器散热能力的评估需要压降-流量曲线和换热量-流量曲线。
During the process of gravel-packing in horizontal Wells, there are the filtration flow of the carrier fluid to the formation and the exchange flow through the screen slots.
由于携砂液向地层的滤失以及通过筛管缝隙的流体质量交换，水平井砾石充填过程中冲筛、井筒环空两个流动系统均为复杂的变质量流。
