吸附式制冷循环质量迁移及回热型循环的热力学分析 总被引:1,自引:0,他引:1
本文建立了吸附式制冷基本循环和连续回热循环的热力模型,研究和发展了有蒸汽质量迁移的新型回热循环。新型循环通过管道连通高低压床体,使蒸汽贯流直至双床压力达到平衡,之后系统开始回热,直至两床体温度达到平衡。通过对理论模型的计算,将其与基本循环进行了比较。文章的结论有益于加深对新型循环特性的认识,从而为优化实际循环系统提供了切实可行的方法。 相似文献

A three-dimensional linear instability analysis of thermocapillary convection in a fluid-porous double layer system, imposed by a horizontal temperature gradient, is performed. The basic motion of fluid is the surface-tension-driven return flow, and the movement of fluid in the porous layer is governed by Darcy's law. The slippery effect of velocity at the fluid-porous interface has been taken into account, and the influence of this velocity slippage on the instability characteristic of the system is emphasized. The new behavior of the thermocapillary convection instability has been found and discussed through the figures of the spectrum. 相似文献
