【摘要】：隨著社會(huì)的快速發(fā)展，人們乘坐飛機(jī)出行的頻率越來越高，雖然每年高峰時(shí)期中國各大機(jī)場均人滿為患，但是飛行于我國上空的大型客機(jī)均來自國外進(jìn)口，為了抓住未來大型客、貨機(jī)市場，中國需要加緊研發(fā)自己的大型飛機(jī)。與此同時(shí)誕生的如何營造飛機(jī)客艙環(huán)境的問題給了我們暖通行業(yè)一個(gè)契機(jī)，良好的客艙內(nèi)環(huán)境是保證乘客及乘務(wù)人員健康舒適及安全的關(guān)鍵因素。對于客艙環(huán)境的營造，目前常用的手段是采用CFD方法進(jìn)行模擬，為客機(jī)座艙的環(huán)境控制系統(tǒng)設(shè)計(jì)提供相關(guān)依據(jù)。目前市場上已經(jīng)出現(xiàn)了將近50余款的商用CFD模擬軟件，但這些模擬軟件主要被國外的研究單位或者公司所有，價(jià)格昂貴、且研究者很難將最新的研究成果加入到這些軟件中，因此，開發(fā)具有自主知識產(chǎn)權(quán)的CFD模擬軟件具有極其重要的科研價(jià)值。作者在導(dǎo)師的室內(nèi)環(huán)境模擬程序VORTEX上進(jìn)行大量改進(jìn)，從而使其能更好地適用于飛機(jī)座艙環(huán)境的氣流組織模擬。 首先，本文對目前的客機(jī)座艙環(huán)境進(jìn)行了闡述分析，，了解了常用于客機(jī)座艙的氣流組織形式，并對目前常用的混合送風(fēng)及正處于理論研究階段的地板送風(fēng)及座椅送風(fēng)進(jìn)行了介紹。 其次，本文對建筑室內(nèi)環(huán)境模擬的理論基礎(chǔ)進(jìn)行了研究，結(jié)合數(shù)值模擬程序建立了基本的控制方程組，根據(jù)數(shù)值模擬的求解步驟列出了控制方程組的離散及基本的求解方法。 第三，本文針對導(dǎo)師參與研發(fā)的室內(nèi)環(huán)境數(shù)值模擬程序VORTEX的功能、模型及求解方法進(jìn)行了簡要介紹。 第四，本文對VORTEX前處理程序進(jìn)了相關(guān)數(shù)據(jù)錄入接口的完善，并對其計(jì)算代碼進(jìn)行了修改與調(diào)試。 最后，本文利用修改后的VORTEX程序與成熟商業(yè)軟件AIRPAK進(jìn)行模擬結(jié)果對比分析驗(yàn)證了其用于飛機(jī)座艙模擬的可靠性，并對兩種用于客艙的不同送風(fēng)方案進(jìn)行了氣流組織的詳細(xì)模擬，分析其各自的優(yōu)缺點(diǎn)，為國產(chǎn)大飛機(jī)座艙供氣方案做出了初步探討。
[Abstract]:With the rapid development of society, people travel by air more and more frequently. Although the major airports in China are overcrowded every year during the peak period, the large passenger planes flying over our country are all imported from abroad. In order to capture the future market for large passenger and cargo aircraft, China needs to speed up the development of its own large aircraft. At the same time, the birth of the problem of how to create an aircraft cabin environment gives us an opportunity for the HVAC industry, a good cabin environment is a key factor to ensure the passengers and crew health, comfort and safety. For the construction of cabin environment, the commonly used method is to use CFD method to simulate the environment control system of passenger cabin, which provides the relevant basis for the design of cabin environment control system. At present, there have been more than 50 commercial CFD simulation software in the market, but these simulation software are mainly owned by foreign research units or companies, which are expensive, and it is very difficult for researchers to add the latest research results to these software. Therefore, the development of CFD simulation software with independent intellectual property rights has extremely important scientific research value. The author has made a great deal of improvement on the tutor's indoor environment simulation program VORTEX, so that it can be more suitable for airflow simulation of aircraft cockpit environment. First of all, this paper describes and analyzes the current cabin environment of passenger aircraft, and understands the airflow pattern commonly used in the cockpit of passenger aircraft. It also introduces the mixed air supply and the floor air supply and seat air supply which are in the stage of theoretical research. Secondly, this paper studies the theoretical basis of building indoor environment simulation, and establishes the basic control equations combined with the numerical simulation program, and lists the discretization and basic solving methods of the control equations according to the solving steps of the numerical simulation. Thirdly, this paper briefly introduces the function, model and solution of the indoor environment numerical simulation program VORTEX. Fourthly, this paper improves the interface of VORTEX preprocessing program, and modifies and debugs its calculation code. Finally, the simulation results of the modified VORTEX program and the commercial software AIRPAK are compared and analyzed to verify the reliability of the simulation of the aircraft cockpit, and the airflow organization of the two different air supply schemes for the cabin is simulated in detail. Their respective advantages and disadvantages are analyzed, and a preliminary discussion is made for the domestic large aircraft cockpit gas supply scheme.
