A general purpose program for computing : 3-D flows has been extended for two-phase flows with topologically complex interfaces. The 3- D interfaces are tracked by employing a coupled level set and volume-af-fluid (CLSVOF) method which not only can calculate an interfacial curvature accurately but also can achieve mass conservation well. The program has been tested through the computations of bubbles rising in a liquid. The numerical results are found to compare well with the results reported in the literature.

The safety and comfort of car seats were studied by utilization of engineering analysis/ experiment and human engineering data. As important factors of the static seating comfort, static spring constant, body pressure distribution, driving posture were discussed. In connection with the dynamic seating comfort, vibrational characteristics of domestic car seats (natural frequencies, damping, frequency spectrum, transmission ratio) were measured and discussed. Finally, the safety of the seat was analyzed and evaluated through calculation and experiments.
