摘要：對(duì)轉(zhuǎn)螺旋槳的非定常激振力直接影響著對(duì)轉(zhuǎn)槳的噪聲性能及振動(dòng)特性,準(zhǔn)確預(yù)報(bào)對(duì)轉(zhuǎn)槳的非定常性能可以更好地為對(duì)轉(zhuǎn)槳設(shè)計(jì)工作服務(wù)?；谟?jì)算流體力學(xué)(CFD)中雷諾平均納維-斯托克斯(RANS)方法,對(duì)對(duì)轉(zhuǎn)槳非定常水動(dòng)力性能預(yù)報(bào)方法進(jìn)行研究。通過對(duì)前后槳區(qū)域及交界面處網(wǎng)格精細(xì)劃分,結(jié)合滑移網(wǎng)格特點(diǎn),考慮每一時(shí)間步內(nèi)旋轉(zhuǎn)角度的對(duì)應(yīng)性,進(jìn)行合理的計(jì)算設(shè)置,提高對(duì)轉(zhuǎn)槳的非定常性能預(yù)報(bào)精度。進(jìn)行了2對(duì)對(duì)轉(zhuǎn)槳方案的非定常水動(dòng)力性能數(shù)值模擬,與試驗(yàn)數(shù)據(jù)的比較分析驗(yàn)證了預(yù)報(bào)方法的準(zhǔn)確性和可行性。
