Basic Thermodynamics - CERN Accelerator School
... A thermodynamic system is in thermodynamic equilibrium when all its state variables remain constant with time: there is no net flow of matter or energy, no phase changes, and no unbalanced potentials (or driving forces) within the system. A system that is in thermodynamic equilibrium experiences no ...

Advantages of Plate-Type Heat Exchanger over Tube-Type
... A high-performance heat exchanger should be used in the evaporator and condenser of Ocean Thermal Energy Conversion (OTEC) since the utilizable temperature difference is small (about 20°C). It is generally said that the plate-type and the double-fluted tube-type heat exchangers are suitable for an O ...
