Abstract
In this study, the effects of the principal geometric parameters in a helix ribbed lip seal on the pumping performance are systematically investigated, through a combined finite element analysis/computational fluid dynamics simulation approach. It is shown that the sealing performance of the modified seal based on the geometrical parameters suggested by the numerical simulations is significantly better than that of the original seal model. The results presented in this study provide a versatile and cost-effective means to derive a set of basic guidelines for designing the conventional helix parameters in such a way as to maximize the reverse pumping effect.
