adiabatic process

Leishear suggests that it can ignite explosive gas, too, a conjecture that I find convincing, having known that a gas bubble within a liquid medium, when it collapses during the passage of shock waves, will reach an extreme temperature due to adiabatic compression. Physicists have measured, e.g., its light emission.

In a vapor cycle system, the temperature is increased by adiabatic compression and decreases during adiabatic expansion.

Using the split Hopkinson pressure-bar (SHPB) nearly adiabatic compression tests are conducted in the intermediate strain-rate regime ranging from 1000 [s.sup.-1] to 2000 [s.sup.-1].

For calculation purposes it is accepted that during initial compression in individual volume parts, adiabatic compression and isochoric heat transfer (5) can be expressed as:

For the assessment of the exergy losses in the component parts of the refrigerating system, it is needed Figure 1, where the notations indicate: [T.sub.c]--condensation temperature, To vaporization temperature, 2r--vapor state after adiabatic compression, 2ir--vapor state after irreversible compression.

To compress a stream of 1000 kg/hour of ambient air to one bar of power of 17.7 KW is needed at adiabatic compression and it is heated to 64C.
