blade cavitation 解釋
槳葉空化
  • blade : n 1 (殼、草等的)葉片,葉身,葉。2 刀片;(安全)剃刀刀片 (= razor blade); 刀口,刃;刀,劍;...
  • cavitation : n. 1. 【航空】氣穴現象;氣渦現象。2. 【物理學】成穴;空化,(超聲波的)空穴作用;【醫學】成洞,成腔。
  1. To improve the efficiency of solution, the solution method to determine the cavitation range of blade is carried out for each chordwise string, the interaction between strings is included by spanwise iterative procedure
