Impulse-response functions of several detectors used in flow-injection analysis [PDF]
, 1990 A procedure for the determination of the impulse-response function of a detector is given. Its application to photometers, ion-sensitive field effect transistors, a potentiometric detector at constant current and a voltammetric detector shows that the ...

Evaluation of water film by reynolds' equation in deep drawing using high-pressured water jet [PDF]
, 2013 The authors had proposed a deep drawing method using high-pressured jet waters as lubricant. This method aimed to suppress the usage of oil or other chemical lubricants, which might require some additional processes for lubricant removal and become a ...

A Non‐Reciprocal Architected Porous Medium
Advanced Functional Materials, EarlyView.ABSTRACT In several fluid flow, energy‐dumping, and energy‐harvesting applications, a dominant flow direction or dominant resistance direction is desirable. In this study, we propose a simple modular geometry that doubles flow resistance in one direction relative to the opposite direction, while maintaining laminar viscous flow.

Study on Jet Pump Water Injection System for Offshore Platform Based on Energy Conservation
Shiyou jixie, 2017 In order to reduce the energy consumption of water injection in offshore platform, the idea of using jet pump instead of wellhead gate valve has been put forward. Taking the 14 water injection wells on a Bohai platform as case study, the JP1, JP2 and JP3

Comparisons of Hydraulic Performance in Permanent Maglev Pump for Water-Jet Propulsion
Advances in Mechanical Engineering, 2014 The operation of water-jet propulsion can generate nonuniform inflow that may be detrimental to the performance of the water-jets. To reduce disadvantages of the nonuniform inflow, a rim-driven water-jet propulsion was designed depending on the ...

Influence of Axial Clearance on Water-Jet Axial Flow Pump [PDF]
, 2021 Three dimensional Reynolds averaged N-S equation and S-A turbulent model were adopted to simulate the flow field and hydraulic performance of the waterjet axial flow pump with the different impeller axial clearance. The numerical research results show that with the increase of axial clearance size, total pressure and static pressure rise at first and ...
