Since nobody cared to reply let us (you and me) steer-up the matter a little bit. I can't help you regarding the essence of the problem but I may clear couple of things and luckily draw some attention to the problem
If I've understood you correctly you would like to make a device for...
Expansion is limited by thermodynamic characteristics of the working media (gas making work)and ambient conditions where it is exhausted to. In other words the exhaust total pressure (dynamic + static) has to be larger than surrounding ambient pressure.
Thus it would be nice to have expansion...
I am not familiar with ultrasonic welding at all, but I am a little bit familiar with ultrasonic cleaning. Therefore I would recommend ultrasonic cleaning before ultrasonic welding.
Supposedly a term mixed flow means that beside steam there are water droplets (two phase flow). That could happen in low pressure stages when vapour (steam) temperature drops significantly and it is highly undesired. Those droplets are damaging blades and it is a kind of "cavitation"...
My wild guess is that in a manual transmission at nominal RPM (max power) loss is about 5% and in an automatic loss is let say doubled, 10%.
Let us hear the comments.
The question is rather simple but the answer is not.
Lower thermal (heating) value of that mixture of gaseous hydrocarbons and air depends on amount and nature of hydrocarbons. In other words depending on temperature and pressure in a tank and certainly type of the oil plays a role in it...
For a quick and naturally brief reference of materials there is SAE AMS INDEX published every six months meaning it can’t be so expensive.
It gives AMS designation, principal composition, type of semi-fabricate and type of heat treatment-condition of supply (for metal alloys). For metals it...
Well I am neither aware what "ALE approach" is nor what “IS-dyna analysis” is but in engine world bird-strike (ingestion) testing is part of type approval tests.
Once upon a time no "jello birds" but real ones, although already deceased, were launched into a running engine...
Sir Riaan,
Hopefully Mr Dixon’s book will be of some help. I’ve searched the Internet (using Google) a little bit and look what I have found:

Unfortunately I was able to open...
Well I consulted a good old booklet I had bought a century ago:
S.L.Dixon “Fluid Mechanics, Thermodynamics of Turbomachinery”
Pergamon Press 1984, ISBN 0-08-022722-8
It says that generally the specific work done on the fluid (in an axial compressor rotational stage or impeller of a centrifugal...
It is obviously a problem of the electrical generator. Something is wrong with it: either OEM has forgotten to do some necessary tuning between phases (e.g. adjust resistance) or maybe you were supposed to do some fine adjustments. Those are only wild guesses of a mechanical engineer but...
Once upon a time when I was a kid we did water electrolyze experiment in a school. No membrane was used, only those laboratory test tubes over the electrodes, one captivating O2 (probably on anode but being a mechanical engineer also I am not to be trusted in this electro-chemical matters) and...
The site I gave you is rather basic but from those schematic views it is obvious how excentric masses should be determined.
Their centrifugal forces should counterbalance the maximum 2nd order free forces (in Top and Bottom DCs) you have already calculated.
Centrifugal force of rotating...
There are peek hydro power stations operating like that. They are called “reversible” as far as I remember. During periods of low power demand they pump water in a reservoirs-lakes well above their level but at demand peeks they operate as turbines. Therefore when operating as a pump that...
I assume that you are interested in gas turbine (GT) air seals. Mostly they are labyrinth seals and I would dare to say that they are more air flow metering features (like some strange kind of metering orifices) than seals. In fact those seals meters portion of the compressed air flow, which...
In case of stationary gas turbines (industrial or marine) having two-spool gas generator (meaning low and high pressure compressors, each powered by its own turbine) air intercooler could be encountered. Increases efficiency of the compressor (which is axial in most of the cases) reducing...
