If water steam cycles were implemented for higher engine efficiency would the average Joe remember to refill water every day?

If sea water could be used in steam systems in cars driven on arid lands could then cars actually prevent or reverse desertification?

Water vapor cycles can be either

Six stroke engine

Blowing water in the exhaust to boost turbo power recovery
or just Steam turbines

I wouldn't see why not.

No it wont. That much water vapor would be a fart in the wind. I have been to places in africa and the middle east where its very humid all day and night. Just because its desart doesn't mean its dry.

That wont work. Turbochargers are heat engines.
You use that heat to do work. It can drive a turbine or boil water.
Boiling the water is work, if you boil water before the turbine so much sensible heat will be lost to latent heating of the water the exhaust stream wont have a high enough temperature to expreance much of any temperature drop when it goes accrost the turbine, there for wont be able to do any work.
Turbochargers already boost fuel economy by up to 20% on diesels.

Turbochargers are /pressure/ engines, not heat engines. If the water evaporates while crossing the face of the turbine, the steam expansion rate creates a higher pressure differential across its face, thus increasing the power by which it can be driven. The heat is completely circumstantial to this process.

As I vaguelly recall water expands about 1600-times in volume between its liquid and vapor states (assuming equal temperature and external pressure)...explaining why something that weighs 8.3 lbs/gal in liquid form becomes "lighter-than-air" in vapor form.

Both you and Old Tele man are correct.
 

The turbocharger, like all turbines, are mass flow engines. Heat and pressure do work to move a mass of working fluid through the turbine producing power. Think of the turbines in a hydroelectric dam.

I think you just proved his point. A hydroelectric dam uses pressure from the reservoir to run the turbine. From what I know, most lakes are not hundreds of degrees, showing why pressure is the important factor.

EDIT: I didn't see the 'title' of your post, that's exactly what you did! :turtle:

OP: I don't think people would remember to add water everyday. We might remember to do it, but the average Joe would probably not. Think about how many people forget to change their oil or coolant or trans fluid. Now they have to do it every day?!?! Unfortunately, I just don't have faith...

If this worked why isnt it in use on large turbodiesel power generators, ship engines or gas turbine power plants?

I know some engineers I can pitch this idea to. I already know their first reaction will be to laugh at me.

Not to mention the idea of having liquid water droplets in contact with the turbine is a bad idea. Causing drag, erosion things things you dont want.

Question would be what do people do when they run out of NOS or meth? You know, for a chemical intercooler not getting high. :eek:

I pitched this idea to my engineer, after a long awkwardly long peroid of laughter, a string of obscenities which cant be posted her his only responce I can repeat on here is "some one failed thermo".

The idea that heat is circumstantial to a turbochargers turbine is laughable to say the very least.
If it isnt why are all turbine calculations done with temperture differential?

heat is circumstantial to pressure. The temp differential calculation gives you an idea of how much pressure is generated using the temp diff across the face of the turbine.

Turbines are not heat engines, they are pressure differential engines. Your 'engineer' is mixing up principles.

If you don't believe me, put a vacuum cleaner nozzle on the exhaust out port of a turbo, or just blow compressed air through the turbine inlet.

BUT PRESSURE AND TEMP DIFFERENTIAL BLAH BLAH BLAH

No. Just no. If you wanna try it again, blow some compressed propane through it. You'll not only freeze the turbine blades from the complete lack of heat energy in the propane as it vaporizes, but it will spin and create discernible boost if piped into a closed environment.

Heat is not the determining factor in a turbocharger's performance. Pressure and flow are. The heat is circumstantial, but not necessary.

BTW - I've seen some very low compression competition engines feed compressed air to the turbine to spool it while starting up. Typically 2 stroke engines where the OE supercharger has been replaced with a large frame turbocharger.

Lets also keep in mind that not all turbines operate using heat as a source of energy, and thus, since all turbines operate on fundamentally the same principle, turbines, by default, can /not/ be necessarily heat-driven engines as a primary function.

So, I reiterate - pressure differential, not temperature differential, is the primary factor.
