Dear Amir,
Thank you. It is not possible to publish those books or any part of them because of two reasons:
1)those books are all subjected to the copy right, hence nobady can publish them in any way.
2)the pages are too many, (this requires scanning three books, or at least half of them), so it’s not possible and besides the amount of such a file is too large to get uploaded and later you download it (by our internet speed)!

سلام
خیلی خوشحالم که شما سریعا پیام ها رو میخونید و جواب میدید و متشکرم
میخواستم بگم شما سر کلاس خیلی با بچه ها چونه میزنید یا برعکس بچه ها با شماو بعضی وقت ها وقت کلاس بیخودی گرفته میشه..
البته از بحثهای خترج از درس شما هم استقبال میکنیم
good luck

  msjavadi wrote @

سلام،
انتظار دآرم آخرین پیام فارسی رادر حال جواب دادن باشم. من منظورتونو از “چونه زدن” واقعا درک نمیکنم. اینکه بچه ها شانس ابراز نظر را دارن من اسمشو “چونه زدن” نمیذارم . درمورد وقت کلاس هم باید عرض کنم که من تمامی 1:30 را یا درس میدم و این در حالی هست که وقت کلاس شما 1:10 به من اعلام شده و یا در مورد مسائل مربوط به کلاس میگذرونم و حتی اغلب تا خود 8 فرصتی برای استراحت پیدا نمیکنم و این در حالی هست که باز بین کلاسها هم 2 یا 3 دقیقه وقت را هم به جواب دادن سوالهایی میگذرونم که واقعا میشه نگذروند! و البته به خاطرم نمیا د که بحث خارج از درسی هم به این شکل که شما میفرمایین در کار بوده باشه. به هرحال از نظرتون ممنونم اما بعید میبینم نظرتون در روند کلی برای همه تغییری حاصل کنه.

Dear Mr. Javadi
First off all I want to thank with your prompt to teach this lesson good as much you can.
This is my opinion that if you put more homework for us after we see the solution; it will be more makes sense for us.

Best regards

  msjavadi wrote @

Dear Mojtaba,
Thank you for your comment. I encourage you to solve more questions by referring to the above reference books, specially, “White” for fluid mechanics II. The aim of representing your homeworks and their solutions is for teaching purposes and mastering you in solving every kind of problems needs your aspiration in solving and studying extra problems and texts, which is essentially out of my control, ability, time, responsibility and … I will try to help you reaching yourself to the standards mentioned by the ministry of science, research and technology.

سلام آقای جوادی
من این مطلب رو بعد از دادن جواب میان ترم سر کلاس نوشتم
از این که خیلی راحت میتونم با شما ارتباط نزدیک و دوستانه داشته باشم هم خوشحالم وهم از شما تشکر می کنم
راستش با این همه توضیح که شما سر کلاس درباره تصحیح اوراق دادید باز من قانع نشدم به 2 دلیل
یکی اینکه سئوال 1 من همه رو درست نوشتم فقط توضیح فازسی نوشتم که خیر چرخشی است که اگر یادتون باشه موقع تحویل دادن برگه گفتم وشما نگذاشتید من درست کنم ((که قبول حق با شماست)) و شما 20 نمره به خاطر تشخیص اشتباه از من کم کردید
ولی در مورد سئوال 3 که من درست تشخیص داده بودم و فرمول آن را نوشته بودم و پس از انتگرال گیری یه دونه ((ایگرگ)) رانگذاشته بودم باز هم خیلی نمره کم کرده بودید
حالا برای من نکته ابهام اور این است که ملاک نمره دادن شما
تشخیص صحیح بود یا راه حل ریاضی یا جواب آخ به صورت کامل
با توجه به اینکه عده زیادی همین مشکل را داشتند خواهش میکنم مشکل ما را دوباره توضیح دهید

با تشکر

  msjavadi wrote @

ملاک نمره تشخیصی است که شما در برگ پاسخ مینویسید و نه آنچه که در ذهنتان نگه میدارید. اگر غلط بنویسید نمره نمیگیرید، هرچند جواب درست را بلد باشید و برای تفریح غلط نوشته باشید و یا در امتحان اینقدر ارزش نبینید که دقت کنید. حالا اینکه شما از درک چنین مسئله ی بدیهی عاجز هستید، که من نمیتوانم به ذهنیت شما نمره بدهم، خود احتیاج به مراجعه به دکتر روانکاو دارد!

“The privileging of solid over fluid mechanics, and indeed the inability of science to deal with turbulent flow at all, she attributes to the association of fluidity with … From this perspective it is no wonder that science has not been able to arrive at a successful model for turbulence. The problem of turbulent flow cannot be solved because the conceptions of fluids (and of women) have been formulated so as necessarily to leave unarticulated remainders.”

روشی برای حل معادلات دینامیک سیالات محاسباتی از طریق آماری

چکیده :

اخیرا روش شبکه بولتزمن به عنوان یک طرح مطلوب برای شبیه سازی جریانهای سیال از جمله جریان با هندسه های پیچیده /جریانهای مغشوش /جریانهای چند فازی و چند جزئی توجه زیادی را به خود جلب کرده است .که این روش بر اساس مدلهای میکروسکوپی و معادلات جنبشی مسوسکوپی است.هرچند این رهیافت ازروش شبکه گاز منشا گرفته شده است.
با توجه به سادگی الگوریتم ودیگر مزایای آن درچند دهه اخیر به عنوان یکی از روشهای موفق در دینامیک سیالات محاسباتی به کار گرفته شده است.
این روش را میتوان مستقیما”طرحی با سرعتهای گسسته از معادله ی پیوسته ی بولتزمن در نظر گرفت . میتوان از خطی سازیهای مناسب مشاهده کرد که این روش به حل معادلات ناویر استوکس در اعداد ماخ کوچک منجر میشود .از آنجا که معادلات ماکروسکوپی غیر خطی هستند و حل این گونه معادلات شد یدا” به مرزها وابسته اند استفاده از روشهای عددی مرسوم مخصوصا”برا هندسه های پیچیده مشکل است .در حالی که طبیعت جنبشی روش شبکه بولتزمن آن را قادر میسازد تا برای شبیه سازی جریانهای پیچیده موثر تر باشد.ضمنا”معادلات ناویر استوکس که روشهای عددی مرسوم بر پایه آن بنا شده است تنها زمانی صادق هستند که رژیم جریان پیوسته فرض شود در حالی که بسیاری از موارد این فرض برقرار نیست که این مشکل نیز با به کار گیری روش شبکه بولتزمن برطرف میشود زیرا چنین فرضی برای آن در نظر گرفته نشده است.

Dear Sir,
Thank you for your prompt response, highly appreciate your great performance, advises and kind behavior during the passed semester, i have really not seen such great peronalities, character and effoerts among the instructors although i respect others too, but you were an ecxeption.
life is a Journey and passing quickly good for those who enjoy and make it happy for others, whatever will never forgotten is kindness and good memories which you made one of those outstanding moments for us.
Thank you again & wish all the best for you,
A.K

با سلام وخسته نباشید
به اینکه اینجانب دو سئوال اول امتحان پایان ترم را کامل جواب
دادام اما گویا نمره فقط یکی از سئوالها را به من داداید و در ضمن نمره
امتحان تا 28/3 در سایت نبود ومن وقتی ساعت 12شب 30/4 به سایت مراجعه کردم زمان تجدید تمام شده بود لذا خواهشمند است
عنایت فرموده در برگ اینجانب تجدید نظر فرمائید با تشکر
