An investigation is carried out on the systematic analysis of the dynamic behavior of the hybrid squeeze-film damper HSFD mounted a rotor-bearing system with strongly nonlinear oil-film force and nonlinear rub-impact force in the present study. The dynamic orbits of the system are observed using bifurcation diagrams plotted using the dimensionless rotating(More)
A systematic analysis of the dynamic behavior of a gear-bearing systemwith nonlinear suspension, couple-stress fluid flow effect, nonlinear oil-film force, and nonlinear gear mesh force is performed in the present study. The dynamic orbits of the system are observed using bifurcation diagrams plotted using the dimensionless rotational speed ratio as a(More)
The study is focused on the channel design of PEM fuel cell based on numerical simulation to analyze the flow performance. In addition, SIMPLE method was used to calculate the coupling of pressure and the velocity. We investigated the different types of chancel to replace the traditional vertical-straight type. Using CFD software, the main blockage in the(More)
It is a effective new way to investigate different amounts of fiber orientation and cooling tubes of mold on fuel cell bipolar plates by Moldex 3D in mold injection, the simulation of mold flow is investigated by finite element method. In this study, the complex flow behavior of melts under the assistance of mold flow analysis is conducted by examining the(More)
