Lagrangian Optimization of Wall Injected Flows

I am pleased to share some of the results of my research over the past few years. These just appeared as a review article in the Proceedings of the Royal Society A and you can download it from here (and the cool thing about the Royal Society – besides its very professional reviewers – review articles are free access to everyone!)

http://dx.doi.org/10.1098/rspa.2009.0326

I hope that you will enjoy reading this manuscript as it includes many classical ideas with a novel twist as well as some original derivations and solutions for flows at large Reynolds numbers.

The heart of this research resides in the fact that we were able to capture solutions that range from purely irrotational to highly rotational fields using a single formulation. These have different energy signatures and morph according to the energy level they are at. The second law of thermodynamics is then used to identify which of those solutions is the most likely to occur in practice based on the entropy maximization principle. Finally, Kelvin’s minimum energy theorem is extended to open regions thus granting it applicability to a wider class of problems. It is used here to prove that the solution with minimum kinetic energy corresponds indeed to the irrotational motion.

Working on this article is one of the main reasons that I have not been posting recently,

Cheers!

How to add space after \hline in LaTeX tables

Try the following:

\hline \\[-1.0em]

Voila!

Of course, you can change the numbers and units inside the brackets.

How to highlight text in LaTeX

Add the following to your preamble:

\usepackage{color}
\newcommand{\hilight}[1]{\colorbox{yellow}{#1}}

To highlight text in the body of your document, use

\hilight{this is some highlighted text}

Voila!

Of course, you can change the color from yellow to any of the supported colors. For a list of those, check: http://en.wikibooks.org/wiki/LaTeX/Colors

Flashget Script Error/Flashget Recommends bar

In Flashget, go to:

View/Recommendation

and uncheck it.

Obviously, the ads displayed by flashget are generating an internet explorer script error. I never liked that recommend bar anyway.

hyperref and pdfdraftcopy

There seems to be a problem when these two packages are used together. Try adding the following to your preamble – it worked well on my end

\makeatletter
    \def\@DRAFTdimen{% copied from pdfdraftcopy.sty 
    \setlength\LLY{\paperheight} 
    \addtolength\LLY{-\textheight} 
    \addtolength\LLY{-\headheight} 
    \addtolength\LLY{-\headsep} 
    \addtolength\LLY{-1in} 
    \addtolength\LLY{-3pt} 
    \setlength\LLX{1in} 
    \ifodd\value{page}% was \thepage 
    \addtolength\LLX{\oddsidemargin}\else 
    \addtolength\LLX{\evensidemargin}\fi 
    \setlength\URX{\textwidth} 
    \setlength\URY{\textheight}
}
\makeatother

Voila!

Make Nomenclature in WinEdt

First, you need to download this file

http://www.winedt.org/Macros/LaTeX/MakeNomencl.php

Save it in the “Exec/MiKTeX” folder under your WinEdt path, e.g.

C:\Program Files\Winedt Team\WinEdt\Exec\MiKTeX

in WinEdt, do the following

1. Right click on the Menu bar
2. Select “Menu Steup”
3. Double click on any of the menus where you would like your make nomenclature command to go (Accessories would be a good candidate)
4. On your upper left, choose Insert->Macro
5. Name the new command (Make Nomenclature)
6. Under Macro, type the following: Exe('%b\Exec\MiKTeX\MakeNomencl.edt');

Voila!

7zip Batch Zip

First, make sure that the 7zip directory is in your path. Usually, it is located at

C:\Program Files\7-Zip

Next, write the following in batch file

Zip all files in a directory

for /f %%A in ('dir /b') do 7z a -tbzip2 "%%A.bz2" "%%A"

Zip files with a specific extension in a directory (download batch file)

for /f %%A in ('dir /b *.txt *.dat') do 7z a -tbzip2 "%%A.bz2" "%%A"

Save and run in the directory where you want to zip the files.

Here, I am compressing using bzip2 (notice the switch: –tbzip2). You can change that to

-tzip for zip

-tgz for gz

-t7z for 7z

some more examples here.
