82 Times as high as the flow rate at the inlet; the velocity profile in the lower region is relatively uniform, and changes at the exit from a parabolic shape towards a plug flow as Re increases; The strong circulating flow in the upper region is very favourable to evaporization of heated fluid because it not only forces all the heated fluid to flow through the liquid surface and, therefore, to evaporate effectively, but also causes a large part of fluid to recirculate to the liquid surface and, therefore, to get a second opportunity of evaporization. In addition, the uniform velocity profile in the lower region is also favourable to crystallizing process.

轴向进料蒸发室进口管侧上方有强烈的循环流存在，循环流流量为进口流量的1.48～1.82倍；循环流下部流速分布较均匀，出口区流速在低Re时为抛物线分布，高Re时接近活塞流；强烈循环流的存在不仅迫使加热流体全部流经液面及其附近进行充分蒸发，而且之后还使相当部分流体再次循环回到液面及附近进行二次蒸发，对蒸发操作十分有利；蒸发室下部流速的均匀分布亦有利于蒸发结晶过程。
