课程內容介紹

本課程主要分爲兩大塊，第一塊基于實驗室煤粒瓦斯解吸擴散，此擴散模型又細化爲雙孔擴散、單孔擴散、單孔時變擴散，並以此擴散模型爲基礎，構建煤層瓦斯運移模型。第二塊爲基于煤層中煤與瓦斯流固耦合模型，講解煤層瓦斯抽采過程中煤岩體的滲透率的演化，此模型也適應煤層氣、頁岩氣開采。本文改進已有的單孔介質模型的滲透率，適應于煤體雙重孔隙-裂隙介質模型。采用PDE模塊對煤基質中瓦斯擴散、煤體變形控制進行處理，采用達西接口處理裂隙滲流方程。本課程適應于剛入門comsol的學習者，准備在煤岩中獲得流固耦合建模技巧以及在煤體損傷變形、非達西滲流、熱流固方面繼續學習者，後續還會繼續更新相關教程，敬請期待

課程大綱：

實驗室煤粒吸附/解吸、擴散
煤層瓦斯流固/熱流固抽采(注水、注氣、注熱）
采空區瓦斯流動
鑽孔周圍損傷變化

學長，課已經買了，第11講模型的插值和部分細節沒展示，可以私發一下模型嗎？

體應變對時間求導，可以用comsol內置求導函數d(f,t)。

学长你好，我对氣固耦合模型-煤层变形方程有个疑问，里面的地应力通过通量/源进行设置，我的理解是压应力为负，但实际模拟中发现，正值是压应力，您的视频也用的正值5MPa，我不太理解这一块，谢谢您的指点

請問後處理的作圖部分，橫坐標弧長是什麽東西？

我看變形控制方程就是通過將變形協調方程代入到本構方程，再將本構方程代入力平衡方程中，固體力學模塊就包含了這三個方程，爲什麽煤層變形控制場不直接用固體力學模塊，而要費勁的用一般形式偏微分方程，這點不太理解，望解答，謝謝

你好，想请教一下，买课后下載下来的源文件，每个研究步骤里，只有瓦斯滲流场是可用的，瓦斯扩散场和煤岩变形显示的不适用，那就起不到流固耦合的作用了吧，前面那么多公式，只有滲流场起作用，扩散场和变形控制不起作用？

Outward bound." "We have seen one of the famous bells of Japan, or rather of Kioto, for it is this city that has always been celebrated for its bells. The greatest of them lies on the ground just outside of one of the temples, and it is not a piece of property that a man could put in his pocket and walk off with. It is fourteen feet high, twenty-four feet in circumference, and ten inches thick. How much it weighs nobody knows, as the Japanese never made a pair of scales large enough to weigh it with. The Japanese[Pg 298] bells have generally a very sweet tone, and to hear them booming out on the evening air is not by any means disagreeable. The art of casting them was carried to a state of great perfection, and stood higher, two or three centuries ago than it does at present. Allingham stamped his feet on the carpet. "I will not listen to such talk, Mrs. Masters! A woman of your age and supposed sense to lend ear to such nonsense. I'm ashamed of you." "No, I'm not," grumbled the Doctor, "I've had enough of this wild-goose chase. And besides, it's nearly dinner time." "Nobody but a servant, and a pretty one," the other said. "It is a pity, sir, that you did not arrive a day sooner, then you might have witnessed great barbarity of the Germans. If you walk on a little farther along the canal, you will see three persons hanging from a tree near Haccourt; one of these is a boy of fourteen. Nobody was allowed on the road, and as a patrol met these three persons, they concluded immediately that they were francs-tireurs, strung them up on the tree, without a trial of any sort, and in addition shot each a bullet through the head. To-day another patrol arrived and had the effrontery to tell the members of the Maastricht Red Cross that the boy had murdered a captain. And we are not allowed to remove the corpses. Horrible!... horrible!" But never mind, vacation's coming. Julia is going abroad this summer-- Further on, in the temple stables, open to the sky and surrounded by a colonnade of carved and painted pillars, some women, in silken sarees of dark hues, were waiting on the bulls and the tiny zebu cows, feeding them with the flower offerings strewn on the mosaic pavement of the courtyard. "I can't make it out no more than you kin," assented Si. "And I've thought o' that crazy idee, too. You know them boys over there in Rousseau's old division was under Sherman once before, when he was in command at Louisville, and they say that he got crazier'n a locoed steer—actually looney, so's they had to relieve him and send him back home to git cured. They'd be really scared about things, but their officers heard old Pap Thomas say that things wuz goin' along all right, and that satisfied 'em. I ain't goin' to worry so long's old Thomas is in command o' the Army o' the Cumberland, and we're in it. He'll take care that things come out straight." "Have you many books?" "Unto the ends of the earth—Hastings. There's a friend of Ades there wot'll guide me into the Spirit's ways." Isabella de Boteler placed the stool so that her own face might be in the shade, at the same time that the light played full upon that of the monk. They sat an instant silent; and as the baroness bent her eyes upon the father, she saw, in the deep marks on the forehead, and in the changed hue of his circling hair, that he had paid the price of strong excitement; but yet she almost marvelled if the placid countenance she now gazed upon could belong to one who had dared and done so much. At length she spoke. HoME 朴妮唛种子下载全集ENTER NUMBET 0019www.vajr.com.cn
