摘要：

In　order　to　reveal　the　effect　of　flow　characteristics　on　the　load　capacity　of　oil　cavity,　the　flow　of　round　Rayleigh　step　cavity　in　hydrostatic　lift　was　divided　into　three　regions:　the　axisymmetric　jet　impinging　flow,　radial　source　flow　and　film　flow.　The　computational　fluid　dynamics　(CFD)　method　was　used　to　build　a　calculation　model　and　the　influences　of　geometry　(e,　h)　parameters　and　the　Reynolds　number　on　the　vortices　were　simulated.　The　results　show　that　there　are　complex　vortices　in　the　flow　field　of　the　round　Rayleigh　step　cavity,　of　which　the　pressure　is　higher　than　parallel　disks　flow.　The　number　of　vortices　is　different　from　1　to　4　with　the　Reynolds　number　of　200
