熱聲耦合導致不穩定性的過(guò)程是什么
熱聲耦合的現象最早發(fā)現于1777年,其本質(zhì)是一種熱能和聲能之間相互轉化、相互影響的過(guò)程.在一些開(kāi)式燃燒里,燃燒不穩定性被研究較多,例如火箭推進(jìn)器的燃燒和燃氣渦輪機等.熱聲耦合現象導致的燃燒不穩定性(thermoacoustic combustion instability)一直是一個(gè)研究重點(diǎn)[1—6].在內燃機這樣的閉式燃燒研究過(guò)程中,對于熱聲耦合現象一直有所認識,有研究表明,汽油機的爆震現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(guò)程中[7],在燃燒室中布置了多點(diǎn)壓力測試傳感器,發(fā)現:在自燃的開(kāi)始期,燃燒室內存在著(zhù)巨大的局部壓力差異.并且指出,在大多數情況下爆震所誘發(fā)的壓力波動(dòng)主要表現為燃燒室內的聲學(xué)特性.在閉式燃燒室中,燃燒壓力的時(shí)間歷程存在振蕩,這種振蕩具有多頻率特性。
熱聲耦合導致不穩定性的過(guò)程是什么
熱聲耦合的本質(zhì)是空間中熱能與聲能相互轉化的現象,目前,國內外熱聲領(lǐng)域的研究主要集中在熱聲制冷,火箭推進(jìn)器等方向。在內燃機領(lǐng)域,雖然研究者們已認識到燃燒室的壓力振蕩與燃燒過(guò)程尤其是爆震燃燒關(guān)系十分緊密,然而由于內燃機燃燒過(guò)程中聲學(xué)振蕩的復雜性,目前聲波在燃燒室中的具體作用如何仍然沒(méi)有定量描述,因此對內燃機燃燒中的熱聲耦合問(wèn)題進(jìn)行研究具有重要意義。為更深入了解燃燒過(guò)程中壓力的聲學(xué)振蕩現象,在分析KIVA的流場(chǎng)求解算法基礎上,根據KIVA的流場(chǎng)求解方程組推導出能夠運用于內燃機燃燒過(guò)程中熱聲耦合計算的波動(dòng)方程。該方程表明內燃機燃燒室的聲波受到多個(gè)源項的激勵,包括化學(xué)反應放熱、粘性耗散、湍流產(chǎn)生項和耗散項、熱傳導、焓耗散等,具有三維非穩態(tài)瞬變的特點(diǎn),必須與KIVA的模擬相結合進(jìn)行求解。根據所得方程構造相應的差分方程,給出了在與KIVA相結合時(shí)計算的穩定性條件及其數學(xué)證明。
