Hydraulic Pressure Extremes Ratio & Extremes Ratio Efficiencies

Qi Maolin

Strategic Study of CAE 2001, Volume 3, Issue 4,   Pages 73-75

Abstract: This article applies basic formula to the calculation of a relationship between the hydraulic pressure extremesratio of hydraulic system and the extremes ratio efficiencies.This relationship shows that the greater the hydraulic pressure extremes ratio is, the lower the extremesratio efficiencies are.The article holds that the hydraulic pressure extremes ratio can be designed and chosen.

Chemical probe systems for assessing liquid–liquid mixing efficiencies of reactors

Frontiers of Chemical Science and Engineering 2023, Volume 17, Issue 10,   Pages 1323-1335 doi: 10.1007/s11705-022-2275-7

Abstract: Liquid–liquid mixing, including homogeneous and heterogeneous mixing, widely exists in the chemical industry. How to quantitatively characterize the mixing performance is important for reactor assessment and development. As a convenient and direct method for mixing characterization, the chemical probe method uses some special test reactions to characterize the mixing results. Here, the working principle and selection requirements of this method are introduced, and some common chemical probe systems for homogeneous and heterogeneous mixing processes are reviewed. The characteristics and applications of these systems are illustrated. Finally, the development of the new system is proposed.
