Simulation of automotive fuel tank filler pipe flows

摘要

The flow behaviour during automotive refuelling is gaining greater importance due to recent pollution laws and contemporary trends in automotive fuel system design. A comprehensive study is reported on the simulation of flows within automotive filler pipes by means of a volume-of-fluid method. Virtual optimisations of the filler pipe geometry and the inlet and outlet shape are presented with the aid of the numerical approach. The results may be useful for the discussion of similar refuelling flows in non-automotive applications, too.
