hermodynamic System Thermodynamic System • Any three-dimensional region of space that we isolate for study. • More specifically – The system is the material contained within this volume we have chosen to study. ou the analyzer must define You, the analyzer, must define the system!

ypes of Thermodynamic Systems Types of Thermodynamic Systems • Closed System: no mass is permitted to cross the oundary only energy boundary, only energy • Open System: both mass and energy may cross oundary; Pumps, Compressors, Turbines, Heat boundary; Pumps, Compressors, Turbines, Heat Exchangers • Isolated System: neither mass nor energy may EGN 3358 - Thermo-Fluids Heat Transfer 11 cross system boundary.
