Cartoons. How about some hardware?

You want it delivered?

For what purpose?

Anyway you are already down one straw. You have never generated a
single novel idea in your entire life.

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

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.


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

Maybe you unnerstand Maxwell's equations.

Show us what you got.

Commercially available stacked flat plat heat exchangers are far more
efficient.. (no need for a working fluid, greater surface area, higher
heat transfer coefficient.) .

Or just google

"stacked flat plate heat exchangers"

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
to pick up the burden...

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?

You are a stupid as you buddy. John's website is well known on the
electronics newsgroups, but you two can't find it.

Do either of you ever get ANYTHING right? John owns a electronics
design & manufacturing business in San Francisco. All you idiots do is
spin useless ideas, while John is designing & building things to complex
for your small, lying minds. He is right downtown, and has shown
pictures of his nw business location and new products on another
newsgroup. All you two do is a pathetic troll dance.

Because it's easier than trying to transfer directly from a gas to a

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

Only the application is new on that one.

At least someone is on topic.

The heat transfer coefficient is an order of magnitude greater with
particle bed fluidization.

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.

Are you talking about something like auto radiators when you
say radiator?

Yes.  With fluidization all you need is a single pipe.
Click to expand...
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?

Your particles are going to be
separated by the moving air, so it isn't clear how you expect to get
improved heat transfer.
Click to expand...
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.
