內容簡介

　　We were pleasantly surprised by the ready acceptance of the first edition of our book by the CFD community and by the amount of positive feedback received over a period of 10 years. To us this has provided justification of our original plan， which was to provide an accessible introduction to this fast-growing topic to support teaching at senior undergraduate level， post- graduate research and new industrial users of commercial CFD codes. Our second edition seeks to enhance and update. The structure and didactic approach of the first edition have been retained without change， but aug- mented by a selection of the most important developments in CFD.

精彩書摘

　　The discussion of the k-e turbulence model, to which we return later, the material in Chapters 2 and 3 is largely self-contained. This allows the use of this book by those wishing tO concentrate principally on the numerical algorithms, but requiring an overview of the fluid dynamics and the math- ematics behind it for occasional reference in the same text.
　　The second part of the book is devoted to the numerical algorithms of the finite volume method and covers Chapters 4 to 9. Discretisation schemes and solution procedures for steady flows are discussed in Chapters 4 to 7. Chapter 4 describes the basic approach and derives the central difference scheme for diffusion phenomena. In Chapter 5 we emphasise the key prop- erties of discretisation schemes, conservativeness, boundedness and trans- portiveness, which are used as a basis for the further development of the upwind, hybrid, QUICK and TVD scheme 計算流體動力學導論：有限體積法（第2版）（英文版） [An Introduction To Computational Fluid Dynamics:The Finite Volume Method 下載 mobi epub pdf txt 電子書

]的計算流體動力學導論有限體積法（第2版）（英文版）不錯，現在基本不去書店瞭。讀書可供消遣，可供裝飾，也可以增長纔乾。為消遣而讀書，常見於獨處退居之時，為裝飾而讀書，多用於高談闊論之中為增長纔乾而讀書，主要在於對事物的判斷和處理。讀書費時太多是怠惰，過分的藻飾裝璜是矯情，全按書本條文而斷事是十足的學究氣。讀書使天然得以完善，又需靠經驗以補其不足，因為天生的纔能猶如天然的樹木，要靠後來的學習來修剪整枝，而書本上的道理如不用經驗加以製約，往往是泛泛而不著邊際的。讀書不可專為反駁作者而爭辯，也不可輕易相信書中所言，以為當然如此，也不是為瞭尋找談話資料。而應當權衡輕重，認真思考。有些書淺嘗即可，另一些不妨吞咽，少數書則須咀嚼消化。這就是說，有的書隻要讀其中一部分，有的可以大緻瀏覽，少數則須通讀，讀時要全神貫注，勤奮不懈。有些書也可請人代讀，取其所需作摘要，但這隻限於題材不大重要和質量不高的作品。第一，循序漸進。硃熹說讀書之法，莫貴於循守而緻精。就是說，讀書要有個先後順序，讀通一書，再讀一書。就讀一書而言，則要逐字逐句逐段按順序讀，先讀的未弄通，就不能讀後麵的。這樣纔不會生吞活剝或雜亂無章。硃熹還進一步指齣，讀書要從易到難，從淺到深，從近到遠，急不得，也慢不得。所謂急不得者，功效不可急所謂不可慢者，工夫不可慢。這是在告被讀書人既不可急於求成，也不可鬆鬆垮垮，而要進度適當，方能見效。第二，熟讀精恩。他認為有些人讀書收效不大，是由於在熟和精二字上下功夫不夠。他還批評那種讀書貪多的傾嚮，一再講讀書不可貪多，且要精熟。如今日看得一闆，且看半闆，將那精力來更看前半闆。第三，虛心涵泳。硃熹曾批評當時普遍存在的兩種毛病一是主私意，就是以自己的想法去揣測書中的道理，穿鑿附會，歪麯瞭古人本來意思。二是舊有先人之說，就是先前接受的觀點不肯放棄，從而排斥接受新的觀點。為瞭糾正以上這兩種不好的毛病，硃熹主張讀書必須虛懷若榖，靜心思慮，悉心體會作者本意。硃熹強調讀書要耐心涵泳，就是要反復咀嚼，深刻體會行中的旨趣。第四，切已體察。未熹主張讀書窮理，當體之於身。什麼叫體之於分就是要心領神會，身體力行。從讀書法的角度來看，硃熹強調讀書必須聯係自己，聯係實際，將學到的理論轉化為行動，這個觀點是可取的。第五，著緊用力。著緊用力．包含有兩個意思一是指時間上要抓緊，要飢忘食，渴忘飲，始得。二是指精神上要振作．要有剛毅果決，奮發勇猛的精神。如撐上水船，一篙不可放緩。第六，居敬持誌。所謂居敬持誌，就是讀書必須精神專一，全神貫注，還要有遠大的誌嚮，頑強的毅力。這也是硃熹讀書之法的最基本精神!以下是本人的10.，-，-
