TVD schemes are a good place to start. If you search on CFD "Shock Capturing" Schemes, you'll find a lot of resources that should be applicable.
Essentially, at the core, what you would like to do is use local gradients to switch between your central differencing scheme (no numerical...
How well can 3DSM, Maya, etc produce engineering drawings?
I think the benefit of the CAD packages is that they have become more of a product management (Siemen's UG Package calls is Product Lifecycle Management), by integrating CAD, CAM, and CAE.
There are just a ton of "stuff" in the CAD...
I suppose the first thing you would need to do is check to see if your exit area is smaller than the critical area. If not, then you should be able to just use Mach tables to find your exit conditions given your area ratio.
Have you done a sanity check on your results? Your exit area is more...
It will. You can think of the air as any fluid. It, like anything else, will exert a force on the next section of liquid proportional to the pressure.
However, when considering air and liquid, there is a significant buoyant force. So, if you did in fact have a "U"-shaped tube, the air pocket...
You can basically start with governing equations. Start canceling out terms until you're left with a differential equation that you can solve.
For example, you can show that radial velocity = 0; you know that d/dz = 0 as well.
They are often times used somewhat interchangably. Head typically has units of length, while pressure has the typical force/area units. The terminology probably comes from the Bernoulli Equation, we can be written such that each term has units of pressure
p + \rho\frac{V^2}{2} + \rho g z = C...
First of all, yes we've had a few "Turbines on cars" threads. More importantly though, this is probably the first that actual has a little reason behind it; I personally find it refreshing.
The question is whether or not you could use a turbine to extract energy during braking. The answer is...
Often times the compressor pressure ratio is a design parameter. From your workbook you have both temperatures and total pressure. Can you use an isentropic relation?
At Station 3, at the end of compression, we essentially have our maximum pressure in the engine (commonly called CDP or PCD compressor discharge pressure).
Across the burner, it you look at the general cycle diagrams

you'll see that we have...
Why don't you start with what you think happens.
You should know what happens through the compressor (the name kind of gives it away). Through the burner, the gas turbine is modeled as a Brayton cycle, or a constant [what] combustion. You should know what happens to temperature.
After that...
You're searching the wrong place, dude. There are tons of entry-level jobs. Maybe craigslist isn't the right place to start your career? See my previous post.
It seems to me you're looking for an excuse for not being able to find a job. Jobs are out there. People work right now, right? It's not like they just started this minimum experience requirement.
I just briefly did a very general search on a governmental job posting website and found TONS. ...
The flow into the compressor is slowed to subsonic to better control the operating conditions. As jared mentioned the airfoils of the compressor have a finite range of efficient operation. If the incoming flow is too slow or even too fast, the flow can have significantly different incident...
Guys,
I am trying to get my citations to do a "through" type thing, ala,. . .gotten using this method [1-4].
Rather, I am getting an entire listing, ala. . . gotten using this method [1, 2, 3, 4].
I am simply using
