Poer expander

I thought I had read that post, but when I went back to review it, I realized that it was a free test and not in the cortex as I had thought. It is a great set of data. I used a linear model of PTC resistance vs temperature.

How Does a Turbo Expander Work? Turbo expanders work on one of the simplest of all natural laws to convert fluid or gas pressure into mechanical movement.

These devices can be found in many applications such as turbochargers, jet engines, power generation plants, commercial refrigerators and at least one interesting form of power regeneration. Conservation of Energy Otherwise known as the "First Law of Thermodynamics," this law states that energy can never be created or destroyed; it can only change forms.

For instance, when an engine burns fuel to move your car, it's essentially just converting energy stored in the form of a liquid gasoline into kinetic energy movement. A turbo expander works by harnessing the pressure and heat of pressurized gas to spin a shaft. Parts and Function A basic turbo expander has two parts: The gas exerts pressure on the expander wheel, causing it to turn.

After pushing on the expander wheel, the gas exits through a hole in the housing. Because it has expended a certain amount of its stored energy to turn the shaft, the exiting gas leaves the turbo expander at a much lower temperature than it went in.

Expander Wheel Shape If you've ever seen a child's pinwheel, then you're somewhat familiar with how an expander wheel works.

The find on the expander wheel's fins catch pressurized gas coming in from the side. If those fins were completely vertical like a paddle-wheelmost of the pressure would just pass over the top. To increase flow, engineers "twist" the whole assembly into a helical shape.

This allows gasses to pass through quickly while expending as much force as possible on the expander wheel.

Compressor-Drive Applications Turbo expanders form exactly half the body of a turbocharger and a big chunk of any jet engine. Although it might not exert much torque force per revolution, pressurized gas can make significant power once the expander wheel gets up to speed.

The expander wheel in compressor-drive applications connects to a matching centrifugal compressor which works just like the turbo expander, but backward via a shaft. The shaft spins the compressor wheel, which shoves air into the engine's combustion chamber.

Cooling Gas exiting the expander is colder and lower-pressure than it was when it went in.

Want to add to the discussion?

The drop in temperature makes turbo expanders useful in refrigeration applications; pressurized gas goes in at a certain temperature, comes out cold and transfers its newfound coldness to the air with a heat exchanger radiator.

Power Regeneration When natural gas leaves the processing plant, it has to do so at enormous pressure to travel the hundreds or thousands of miles to wherever it's going to be used. Before it reaches the end user, the gas must go through a series of valves and restrictors to reduce the pressure so it doesn't blow anything up at the point of use.

These pressure-drop requirements present an opportunity for energy-recapture using turbo expanders; the turbo expander drives a generator that sends electricity back into the electrical grid.Auxiliary Power In some cases, when an output of the BPS is programmed to be always turned on, the BPS can also be used for auxiliary power to operate door .

Because the Power Expander has a light on it that tells you if the battery is connected. We did it at one point. It output to a screen on the LCD screen, that told us if the battery level was below v. scroll expander that operates at an optimal power range. Scroll expander technology has already been successfully demonstrated with carbon dioxide expanders.
