I agree wholeheartedly, the knowledge and experience you gain from actually "building" something from the ground up far exceeds that from reading or learning about it. Conceptually, you can do just fine with books or talking to someone but that only gets you so far. I have seen many A students...

Yeah, I agree totally. The only real way to get a firm grasp on jet engines is to build one.. However, a lot of things have to go right for a gas turbine to function continuously.. and it will be extremely frustrating and very time consuming. I know for me... producing results is a huge...

Gt I understand your curiosity of gas turbines. They are an amazing piece of technology. Its amazing to me that many people do not understand how they work, however they are one of the most simplistic engines, relatively speaking. I started your little venture about 2 years ago, and...

opps I forgot about your other question about the steam valve. I am not sure about that one, but intuitively I would think you can not just shut off a steam supply line without the cooperation of other systems, or the steam emergency blow out valves will be activated... steam pressure...

stages Also, the number of stages is correlated to fit the application. For example, if you have a very large steam pressure upstream that has massive amounts of energy you want to remove every last drop of energy from the steam and convert it to mechanical work (shaft). You do this through...

Finite elemet Thanks, But, I am more looking for a finite element differential of the energy equation in cylindrical coordinates... The free body is set up like a differential slice of pie (3d) with energy flux and work flux in and out of the control volume. Thanks, chris

So, I have searched the globe to find the derivation of the conservation of energy equation in 3D cylindrical coordinates. I have looked in about every heat transfer, thermodynamic, thermofluid books in the library. I have spent about 4 hours on the internet trying to find something, but no...
