You want it delivered?

For what purpose?

Anyway you are already down one straw. You have never generated a

Since you have no IP or web page, perhaps you>ld like to try something
else?

Maybe you want to impress someone with your proficiency in vector
calculus?

Maybe you unnerstand Maxwell>s equations.

Show us what you got.

Yes John has his corporate web page, and it shows some very
interesting products he designed,. Just because you are too stupid to
find it doesn>t mean it doesn>t exist.

I think you>ve made your point Bret. It should be easy for any of
these guys to critique your proposal, particularly John Larkin who is
in the coffee processing business. But as usual, I>m the one who has

Referring to picture 2:

Before we get into the actual physics of it, where would you apply
this? Why are we heating up liquids and then transferring the heat to
a gas? Are you talking about something like auto radiators when you
say radiator?

All ya gotta do is put out the shoe and the idiots step right in to

Is he ashamed of it or what?

This is remins me of the looneytarian posting under the handle
"Caliban."

He said he was running for office but he wouldn>t post his name.

Yes. With fluidization all you need is a single pipe.

Only the application is new on that one.

Huge!

Show your work.

Bret Cahill · Guest

At least someone is on topic.

[quote]Commercially available stacked flat plat heat exchangers are far more
efficient.. (no need for a working fluid, greater surface area,
[/quote]
Fins work in fluidization as well

[quote]higher
heat transfer coefficient.) .
[/quote]
The heat transfer coefficient is an order of magnitude greater with
particle bed fluidization.

I thought I made that clear.

A loser in his own mind.

[quote]I thought I made that clear.

All you>ve ever made clear is that
[/quote]
You cut/snip dodge tech issues like the plague.

On the other hand every time you try to comment on tech issues you
look like a complete idiot, denial of the circular furrows, fields
take 3 months and $100,000 worth of diesel to plow, etc.

The best you can do is post:

LOL!

Cite?

Well that>s one place where I don>t agree. It is obviously always more
efficient to avoid the intermediate step, unless you are talking about
transport, where the liquid covers some distance.

[quote]Are you talking about something like auto radiators when you

Yes. With fluidization all you need is a single pipe.
[/quote]
Yeah I think you are wrong on that. Your particles are going to be
separated by the moving air, so it isn>t clear how you expect to get
improved heat transfer. Perhaps one of the mechanical engineers will
correct me, but I would visualize it as follows:

Consider a thin section perpendicular to the airflow, such that the
liquid 'pipe' is in the center, and welded to the pipe is some
perforated metal. Heat flows through the metal around the holes, which
means the whole thing will heat up and give up heat to the airflow.
But you are suggesting that we have the 'photographic negative' of
that, with little discs of metal surrounded by air. This would result
in *less* surface area with a high delta-T with respect to the moving
air.

No reasoning?

[quote]Your particles are going to be

[/quote]
The reason it isn>t clear is because you never studied fluidization
or, for that matter, anything science or tech related.

You need to get the Pell grant. Write your congressman to expand the
program.

Here>s an easy experiment to get a "feeling" for a heat transfer
coefficient in the same range as condensation.

Cap the bottom of a 4" PVC sewer pipe. Drill a 1/8" hole near the
bottom and run a line to shop compressor. Fill the T with ice water
including some crushed ice or small ice cubes.

Place you hand into the ice water and crank up the compressed air for
40 seconds.

That will cool a drink faster than liquid N2 or CO2 from a fire
extinguisher.

Run away?

You are always running away from any tech discussion because you know
you>ll just make a complete fool of yourself.

Face reality: You have no interest in science or technology.

All you can do here is type:

LOL!

Cite?

You have so little direction or purpose you can be classified
nonfunctional.

I saw the exact same thing on misc.legal where someone legal beagle
claimed it was possible to get arrested for trespassing on a public
road.

You cannot _find_ people that dumb in real life.
