在流动沸腾传热两相流研究中,流型研究一直是众多研究者的兴趣所在。目前有关流型研究的报道均为低粘物系,但高粘流体两相流流型研究,对高聚物生产、食品、轻工等工业有重要应用价值。 浅尾芳久等在透明玻璃管中研究了流动沸腾的流型,表明Mishima等提出的流型划分判据可以较好地区分泡状流、弹状流、环状流。Kamiel等分析比较了大量低粘物系两相流实验数据和几种流型判别式,表明Weisman等提出的判别式可以较好地区分弹状流与环状流。
In the study of flow boiling heat transfer two-phase flow, flow research has been the interest of many researchers. At present, reports on flow pattern are all reported as low-viscous materials. However, the research on two-phase flow pattern of highly viscous fluids has important application value in the industries of polymer production, foodstuff and light industry. Asagawa Akira et al. Studied the flow boiling patterns in a clear glass tube, indicating that the flow pattern classification criteria proposed by Mishima et al. Can distinguish bubble flow, slug flow and annular flow well. Kamiel et al. Analyzed and compared a large number of experimental data of two-phase flow with low viscous system and several discriminant types of flow patterns, indicating that the discriminant proposed by Weisman et al. Can distinguish the slug flow from the annular flow well.
