This research presents theoretical analysis and numerical simulation of combined valves' dynamic characteristics in reciprocating oil-gas multiphase pump. Based on the mathematical model describing valves' motion, a geometric model of pump cavity and combined valves is put forward for numerical simulation in multiphase pump. The simulation is conducted by computational fluid dynamics (CFD) method with its dynamic grid technique. The motion process of suction valve and discharge valve are obtained on the basis of boundary conditions and optimized numerical approaches. And the effects of gas volume fraction (0.1 ∼ 0.9), suction pressure (0.20 ∼ 0.40 MPa) and discharge pressure (1.0 ∼ 3.0 MPa) on valves' motion are reported. The results of pressure distribution, and valves' lift and velocity show that valve plates may cling or rebound and then vibrate after reaching the lift limiter, and the lag angle of one cycle remains 3°under different working conditions. The study could lay theoretical foundation for the design of new type of multiphase pump. ARTICLE HISTORY

“…In pharmaceutical applications, miniature infusion pumps have been developed to inject insulin into patients, but they need to be improved further to achieve better The application of miniature pumps is summarized by Rossetti [57]. Non-rotational miniature size pumps include piezoelectric pump [13,58], electrostatic pump [15,59], electro-osmotic pump [60], ultrasonic pump [17], membrane pump [61,62], peristaltic pumps [63,64], and reciprocation ball pump [65]. These devices are limited by the low flow rate and pressure generated capability [66].…”

In the first place, I would like to express my deepest sense of gratitude to my supervisor, Professor Chan Weng Kong, who was abundantly helpful and offered invaluable assistance, advice, and guidance throughout the work in every step of my research. His sharp sight, patient explanation and continuous encouragement have enlightened me to a more profound and extensive academic future. I would like to thank CNC technician Mr. Kong Seng Ann, Fluid Mechanics Lab technician Mr. Yap Pow Kim and Thermal Fluid Research Lab 1 technician Mr. Yuen Kee Hock for helping me on milling impellers and volutes for my experimental research. Besides, I appreciate all staffs and students in Thermal and Fluid Research Lab for their suggestions and helps. Last but not least, I take this opportunity to express my appreciation to my beloved families. My parents and husband deserve special mention for their inseparable support and endless love through the duration of my studies.
