Research Abstract

Computational program for analysis of two phase flow in micro channel based on stabilized bubble function element finite element method was constructed. In this program code, effect of interface tension is included by the CSF model, and validity of program code could be confirmed by comparing results between experiment and numerical analysis. In addition, stability analysis based on the Helmholtz equation was carried out. Consequently, it appears that cause of resonance can be judged by comparison of angular frequency for time history of pumped liquid volume and result of eigen angular frequency by stability analysis.
