熱聲耦合導(dǎo)致不穩(wěn)定性的過程是什么

熱聲耦合的現(xiàn)象最早發(fā)現(xiàn)于1777年,其本質(zhì)是一種熱能和聲能之間相互轉(zhuǎn)化、相互影響的過程.在一些開式燃燒里,燃燒不穩(wěn)定性被研究較多,例如火箭推進(jìn)器的燃燒和燃?xì)鉁u輪機等.熱聲耦合現(xiàn)象導(dǎo)致的燃燒不穩(wěn)定性(thermoacoustic combustion instability)一直是一個研究重點[1—6].在內(nèi)燃機這樣的閉式燃燒研究過程中,對于熱聲耦合現(xiàn)象一直有所認(rèn)識,有研究表明,汽油機的爆震現(xiàn)象是和燃燒室的聲學(xué)特性有緊密關(guān)系的.美國的Syri-m is在研究汽油機爆震過程中[7],在燃燒室中布置了多點壓力測試傳感器,發(fā)現(xiàn):在自燃的開始期,燃燒室內(nèi)存在著巨大的局部壓力差異.并且指出,在大多數(shù)情況下爆震所誘發(fā)的壓力波動主要表現(xiàn)為燃燒室內(nèi)的聲學(xué)特性.在閉式燃燒室中,燃燒壓力的時間歷程存在振蕩,這種振蕩具有多頻率特性。

熱聲耦合導(dǎo)致不穩(wěn)定性的過程是什么

熱聲耦合的本質(zhì)是空間中熱能與聲能相互轉(zhuǎn)化的現(xiàn)象,目前,國內(nèi)外熱聲領(lǐng)域的研究主要集中在熱聲制冷,火箭推進(jìn)器等方向。在內(nèi)燃機領(lǐng)域,雖然研究者們已認(rèn)識到燃燒室的壓力振蕩與燃燒過程尤其是爆震燃燒關(guān)系十分緊密,然而由于內(nèi)燃機燃燒過程中聲學(xué)振蕩的復(fù)雜性,目前聲波在燃燒室中的具體作用如何仍然沒有定量描述,因此對內(nèi)燃機燃燒中的熱聲耦合問題進(jìn)行研究具有重要意義。為更深入了解燃燒過程中壓力的聲學(xué)振蕩現(xiàn)象,在分析KIVA的流場求解算法基礎(chǔ)上,根據(jù)KIVA的流場求解方程組推導(dǎo)出能夠運用于內(nèi)燃機燃燒過程中熱聲耦合計算的波動方程。該方程表明內(nèi)燃機燃燒室的聲波受到多個源項的激勵,包括化學(xué)反應(yīng)放熱、粘性耗散、湍流產(chǎn)生項和耗散項、熱傳導(dǎo)、焓耗散等,具有三維非穩(wěn)態(tài)瞬變的特點,必須與KIVA的模擬相結(jié)合進(jìn)行求解。根據(jù)所得方程構(gòu)造相應(yīng)的差分方程,給出了在與KIVA相結(jié)合時計算的穩(wěn)定性條件及其數(shù)學(xué)證明。
