Thermosiphon - Wikipedia

Thermosiphon - Wikipedia

Thermosiphon (or thermosyphon) is a method of passive heat exchange, based on natural convection, which circulates a fluid without the necessity of a mechanical pump. Thermosiphoning is used for circulation of liquids and volatile gases in heating and cooling applications such as heat pumps, water heaters, boilers and furnaces.

One is a circulation pump which continuously filters the water supply and supplies the feed pump. The feed pump operates at 120 psi and injects de-ionized water into the process to produce the hydrogen necessary for the chemical to electrical energy conversion.

How to calculate fluid's temperature change in a pump?

How to calculate fluid's temperature change in a pump?

Less intuitively, the heat transfer across the pump control volume is usually assumed to be zero. For fluids near ambient temperatures, this is certainly negligible, and even for fluids at temperature, the heat transfer is usually low relative to the enthalpy/work changes. However, you should keep it .
