The Flow Analysis and Numerical Simulation of the Time-Pressure Dispensing System

Abstract:

The fluid flow of the time-pressure dispensing system was analyzed. Dispensing fluid was analyzed by finite element modeling based on N-S equation. Use CFX module to simulate dispensing process, and obtain the flow fields corresponding velocity & pressure distributions. Study the change rules of the adhesive amount dispensed affected by the inlet pressure, diameter and length of the needle. Finally, compare simulation values with the spectral method for two order approximations, the reliability and applicability of the model is proved.
