【摘要】：面對全球性的環(huán)境與資源危機,如何應(yīng)對當(dāng)今的氣候變化,去盡力改變現(xiàn)有建筑活動中的不良行為模式,并深入探索在現(xiàn)代科學(xué)技術(shù)背景下的人居環(huán)境可持續(xù)發(fā)展模式,已是從事建筑活動的人們所面臨的重大課題。 作為中華建筑文明重要歷史見證的傳統(tǒng)聚落,既體現(xiàn)了建筑與自然和諧統(tǒng)一的思想,更凝聚著我國先人的智慧和才華。它們是在順應(yīng)自然的基礎(chǔ)上,追求建筑與自然環(huán)境的和諧統(tǒng)一,所以更能體現(xiàn)可持續(xù)發(fā)展的環(huán)境意識。它們的許多傳統(tǒng)規(guī)劃和設(shè)計理念都能在低能耗和環(huán)保的前提下去適應(yīng)自然環(huán)境的變化。因此,這些傳統(tǒng)聚落可持續(xù)的規(guī)劃和設(shè)計經(jīng)驗,將對創(chuàng)造現(xiàn)代綠色人居環(huán)境的實踐有著深遠(yuǎn)的指導(dǎo)意義。 此博士論文旨在從建筑氣候?qū)W的角度,探討濕熱地區(qū)傳統(tǒng)聚落規(guī)劃層面的氣候設(shè)計經(jīng)驗。在此課題的基礎(chǔ)上,筆者于2012年申請并獲得一項名為“濕熱地區(qū)古村落原真建筑環(huán)境數(shù)值模擬及其保護、改造策略研究”的國家自然科學(xué)基金資助項目(51208511)。 本文首先,按照建筑氣候?qū)W理論,分析總結(jié)了“夏熱冬暖”的廣東、廣西、福建地區(qū)和“夏熱冬冷”的浙江、安徽和湖南等地區(qū)傳統(tǒng)聚落中行之有效的氣候設(shè)計策略。然后,再采用計算流體動力學(xué)方法(CFD),數(shù)值模擬這些濕熱地區(qū)典型傳統(tǒng)聚落的熱環(huán)境,做到定量、直觀地展示傳統(tǒng)聚落氣候設(shè)計策略所取得的良好效果。 主要模擬內(nèi)容： 1.本文第四章,分別對濕熱地區(qū)“密集”布局型的古村落——湘南上甘棠村和“梳式”布局型的古村落——廣東開平錦江里村的熱環(huán)境進行了三維湍流穩(wěn)態(tài)模擬,以驗證選址、布局、山體、水體、植被的降溫效果。 2.冷巷是濕熱地區(qū)最具特色的氣候設(shè)計策略,故本文第五章以泉州聚寶街112號手巾寮為例,對冷巷的熱環(huán)境進行了三維非穩(wěn)態(tài)模擬。 以上研究工作,較全面地總結(jié)介紹了傳統(tǒng)聚落的被動降溫技術(shù),為當(dāng)今創(chuàng)建綠色人居環(huán)境提供了有益的借鑒。 本文主要的創(chuàng)新點在于：采用目前工程學(xué)界最為流行的計算流體動力學(xué)方法(CFD),對研究對象進行了深入定量的分析,突破了以往對傳統(tǒng)聚落環(huán)境多以定性分析為主的局限,并且在前人的基礎(chǔ)上,研究取得了如下進展： 首先,將冷巷熱環(huán)境的“靜態(tài)模擬”發(fā)展到“三維非穩(wěn)態(tài)模擬”,可動態(tài)演繹“冷巷”被動降溫的全過程。并使今后冷巷的實際應(yīng)用提高到一個新的水平。建立了適合于濕熱地區(qū)傳統(tǒng)村落氣候設(shè)計的三維非穩(wěn)態(tài)模擬模型。 其次,建立了實際聚落環(huán)境的模擬計算方法,將前人所做“理想聚落環(huán)境”數(shù)值模擬提升到“實際聚落環(huán)境”的模擬計算。為總結(jié)我國在傳統(tǒng)聚落中積淀下來的與自然和諧共存的策略與經(jīng)驗,提供了新的有效的手段。 另外,發(fā)展了多孔介質(zhì)的熱環(huán)境模擬模型,提高了計算速度,有效地解決了模擬對象規(guī)模大所造成的計算容量超大的難題。 總之,本文的研究成果表明,數(shù)值模擬方法也是研究歷史建筑與環(huán)境的一個嶄新而有效的手段。
[Abstract]:Facing the global environment and resource crisis, how to deal with the current climate change, try to change the bad behavior pattern in the existing building activities, and explore the sustainable development model of human settlements under the background of modern science and technology, has become a major topic for people engaged in architectural activities.
As an important historical witness of Chinese architectural civilization, traditional settlements not only reflect the idea of harmony and unity between architecture and nature, but also agglomerate the wisdom and talent of the ancestors of our country. They are in pursuit of harmony and unity of architecture and natural environment on the basis of nature, so they are more able to realize the environmental consciousness of sustainable development. The concept of unified planning and design can adapt to the changes of natural environment under the premise of low energy consumption and environmental protection. Therefore, the sustainable planning and design experience of these traditional settlements will have far-reaching guiding significance for the practice of creating a modern green living environment.
On the basis of this topic, the author applied for and obtained a National Natural Science Foundation, which was named "the numerical simulation of the real building environment of the ancient villages in the hot and hot areas and the research on the strategy for transformation" on the basis of this topic in 2012. Help project (51208511).
Firstly, according to the theory of architectural climatology, this paper analyses and summarizes the effective climate design strategies of the traditional settlements in Guangdong, Guangxi, Fujian, Zhejiang, Anhui and Hunan, and then the computational fluid dynamics (CFD) is used to simulate the typical traditions of these hot and humid regions. The thermal environment of settlements can quantitatively and intuitively display the good results achieved by the traditional settlement climate design strategy.
Main simulation content:
1. in the fourth chapter, the three dimensional turbulent steady state simulation of the "dense" layout type of ancient villages in the hot and hot areas - the village of Mantang village in southern Hunan and the "comb type" type of ancient villages - the village of Jinjiang Li in Kaiping, Guangdong, is simulated to verify the cooling effect of the site, the layout, the mountain, the water body and the vegetation.
2. cold lane is the most characteristic climate design strategy in the hot and humid area, so the fifth chapter of this article takes the 112 hand towel squatter in Quanzhou poly street as an example, and carries out the three-dimensional unsteady simulation of the thermal environment of the cold lane.
The above research work summarizes the passive cooling technology of traditional settlements in a more comprehensive way, which provides a useful reference for the creation of green living environment.
The main innovation of this paper is: using the most popular computational fluid dynamics method (CFD) in the field of engineering, the research object is deeply and quantitatively analyzed, which breaks through the previous limitations of the traditional settlement environment with qualitative analysis, and the following progress has been made on the basis of the predecessors:
First, the "static simulation" of the thermal environment of the cold lane is developed to the "three-dimensional unsteady state simulation", which can dynamically deduce the whole process of the cold alley passive cooling, and improve the practical application of the cold alley to a new level in the future. A three-dimensional unsteady model for the climate design of the traditional village in the hot and damp areas is established.
Secondly, the simulation calculation method of the actual settlement environment is established. The simulation calculation of the "ideal settlement environment" numerical simulation made by the predecessors is promoted to the "actual settlement environment". In order to sum up the strategy and experience of the harmonious coexistence with nature in our traditional settlement, the new effective means are provided.
In addition, the thermal environment simulation model of porous media has been developed, which improves the calculation speed and effectively solves the problem of the large calculation capacity caused by the large scale of the simulated object.
In conclusion, the research results in this paper show that numerical simulation is a new and effective way to study historical buildings and environment.
