Experimental investigations on pulsant behaviors of particle flow were carried out on a two-dimensional spouted bed using PIV .

本文基于 PIV 处理颗粒流动图像获得了颗粒流动的瞬时速度；基于功率谱密度分布对瞬时速度的分析结果表明，喷射区轴线的中下部颗粒存在较强的速度脉动，环隙区颗粒速度脉动较弱；研究发现喷动周期与床体压力脉动周期基本一致。

On the basis of an integrated analysis of the geochemical features of these volcanic rock associations,this paper concludes that thebasalts originated mainly from interaction between mantle-derived magma and low-crustal materials, and rhyolitic volcanic rocks resulted from thermal and chemical interaction between basaltic magma and the upper part of crustal materials.Basalts and rhyolites in different cycles have different source regions,and they are products of multiperiodic pulsive layer partial melting.

根据对火山岩地球化学特征的综合分析表明，玄武岩主要为幔源岩浆与下部地壳岩石相互作用的产物，而流纹岩则为玄武岩浆与上部地壳物质进行热及成分交换的结果，不同旋回的玄武岩和流纹岩有不同的源区，为多次脉动分层部分熔融的产物。

A separated model is developed for the recirculating flow and heat transfer in a kettle reboiler tube bundle.

提出了釜式再沸器管束中循环流动换热的分相预报新模型，考虑了管束下部的过冷沸腾及循环液体的侧面引入。

Our two-stage system includes a primary U-beam impact separator and a secondary multi-cyclone dust collector which work together to provide a combined particle collection efficiency in excess of 99.8%. The U-beams, a staggered array of stainless steel channels at the furnace exit plane, capture nearly all of the solids suspended in the flue gas leaving the furnace and internally recirculate these solids to the lower furnace.

两级系统包括一个初级U型钢分离器和一个第二级多旋风集灰器，其共同工作使得颗粒收集的效率超过99.8％。U型钢，也就是在炉膛出口平面处交错排列的不锈槽钢，捕获了离开炉膛的烟气中的几乎所有的固体悬浮物，并以内再循环的方式将这些固体送到炉膛下部。

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。
