Discussion of Research Methods of Flow Visualization in Rotating Machinery |
|
| Abstract: | Modern flow visualization technique is a kind of forward courses crossing technique. Success in flow field expeimenal study is decided by light condition , seed particle, drawning, processing and analysing means of information to flow field. At present, the techniques LIF ,CT ,PIV ,DPIV etc. provide possibility for studying instantaneous spatial unsteady flow fields. Especially, LIF ,PIV ,DPIV methods are applied to the flow fields of rotating machinery supplies good enlightenment for studying further hydro machinery flow fields. Along with all kinds of new technical development , flow visualization technique will become a sort of potential modern practical technique. |
