【摘要】 液环输送是一项新的节能技术.本文对核心与液环两种液体的粘度比S≥100的偏心液环流动,提出水力计算模型,并分别推导了液环为层流及湍流两种流态的流量计算公式,可供生产实际应用.更多还原

【Abstract】 Liquid jacket transportation is a new technique for saving energy.In this paper a hydraulic calculation model is presented for eccentic liquid jacket flow of viscosity ratio S≥l00 of the core and jacket liquids.Calculd atinq formulae of volumetric flow rate have been derived for both laminar anturbulent jacket flows, which can be applied to production practice.更多还原
