Focus on reducing the air consumption of air flotation rail system, a flowrate-amplified
flotation element was recently developed. This new flotation element takes advantage of
rotation flow to intake extra air via an intak hole and thus effectively improves the
flotation height. Compared to conventional flotation element, it can reduced
approximately 50% air consumption, for the same load and flotation height. To have an
advance in understanding of flow phenomenon in flowrate-amplified flotation element,
the experiments and CFD simulations are conducted in this paper. Based on the results,
we found that flowrate-amplifier flotation element can takes a part of kinetic energy of
rotating air to suck extra air. And the intake hole greatly affects the pressure field and
velocity field of flotation element. Additionally, the effects of variant gap height and
supplied flow rate were also discussed. The results indicates that the pressure
distribution will decrease as gap height increases and increase as supplied flow rate
