Abstract The aim of this communication is to clarify some aspects related to the power consumption in continuous Oscillatory Baffled Reactors (OBRs). The first aspect studied is the effect of the flow superimposition on the power consumptions associated to the net flow and the oscillatory flow. The quasi-steady model is used to obtain an expression for the oscillatory flow effect on the net flow power consumption, and vice versa. The expression obtained for the oscillatory flow effect is in good agreement with the one available in the literature, whose deduction is still unknown. The second aspect is the effect of the energy recovery in the power consumption. An analytical expression, function of the pressure drop-velocity phase lag, is derived, showing that the power consumption difference between a system with and without energy recovery can be significant.

振荡折流板反应器中流动叠加效应对功耗的解析计算

摘要 本次交流的目的是阐明与连续振荡折流板反应堆 (OBR) 功耗相关的一些方面。研究的第一个方面是流叠加对与净流和振荡流相关的功率消耗的影响。准稳态模型用于获得振荡流对净流功耗的影响的表达式，反之亦然。为振荡流效应获得的表达式与文献中可用的表达式非常一致，其推论仍然未知。第二个方面是能量回收对功耗的影响。导出了一个解析表达式，即压降速度相位滞后的函数，
