The work I'm going to do is for more normal power plants. I'll tell you more after I actually start my new work. As a mathematician I have to admit that I'm more interested about the mathematical theory behind it and especially about applying that theory in computational methods and improvement of the computational methods and so on.
I'm more excited about the multi phase flow problems part than the power plant part.




A mathematician!! A girl mathematician...

Bookworm, is any of your work (or study) been in nonlinear PDEs/systems that are psuedoperiodic or chaotic? I took a chaos and nonlinear dynamics class this semester.

It was interesting but I have a hard time getting over my deadly aversion to numerical analysis and coding. I absolutely hate it. That's what will probably keep me in analysis even though PDEs are so much fun

I loved PDE the class because in ODEs it was all pretty basic but in PDE every day it was like "ok now we have to learn some complex analysis to solve this", "ok today we have to learn fourier integrals to solve this..." it was so cool the way it pulled from all these corners of mathematics.

--By the way, she said she's only doing two-dimensional turbulent flow. For everyone else out there, that's still really hard . I only learned one-dimensional flow in my undergrad thermofluids I/II courses. And for the satellite system, we only dealt with one-dimensional to approximate losses and performance. We did some preliminary two-D stuff in a CFD program I can't remember the name of...

Can you even DO three-dimensional fluid flow analysis without CFD? I don't think you can can you?

Well this started to get bit off topic so here is a new thread for math and science stuff.
And don't be discouraged to post here some other stuff about math and science too. I know I sometimes get too exited about this and then most of the people don't have any idea what I'm talking about.

One of my interests is in nonlinear stuff, but I'm still doing my masters not my phd so my knoweledge about that is still pretty basic. But my goal is to learn more about it. My theses supervisor is actually doing nonlinear dynamics, but not much numerical things and coding so it isn't necessary. I actually like numerical methods so I will be doing some coding for my theses and for that I have to have another supervisor.

About three dimensional analysis I don't know so much about that as I said earlier I'm only doing my masters and only two dimensional, but I know that the unsolved problems of Navier-Stokes existense of solutions and smoothes of solutions are in three dimensions. I know that there hasn't been any proofs about solutions existing and being smooth in whole R3, but are there some special restricted solutions to spesific cases in three d do you know?

Have to go teach some derivation to a friend who is strugling with math.

So I read some articles from this Finnish popular science magazine. I found interesting one about cosmology and searched for information in English and found this NY Times article.

Here it is if anyone else is interested.

I'm happy that I deal with more practical things myself and don't have to consider things like that when working.

It's like when you're takin your Calc II or III test and you turn to an integral of convoluted combinations of sin and cos and there are infinities in the boundary conditions and you're thinknig OMG HOW DO I SOLVE THIS?!

And then you use Euler's Rule, sin and cos just beautiful turn into e's... you antidifferentiate... and you get e to the negative infinities and zero's and your answer...
