Different tip shapes produce pressures on the plane specimen surface that can vary by a factor of 1.6. In this paper, the authors discuss how pressure and vorticity affect a specimen. When an AFM tip comes close to a specimen, the geometric space between the tip and specimen leads vorticity...
The particular two-phase flow model used is a key factor determining the accuracy of the CFD simulation of a multiphase pump. According to the literature on gas-liquid two-phase models, the two-fluid model was most widely adopted because of its high calculation accuracy compared to other ...
