What is Open System – Closed System – Isolated System – Definition

Whether the system is open system or closed system or isolated system, it is dependent on work and heat which may cross the boundary of the system. Thermal Engineering

Open System – Closed System – Isolated System

Open System – Closed System – Isolated System

closed-open-isolated-systemHeat and/or work can be directed into or out of the control volume. But, for convenience and as a standard convention, the net energy exchange is presented here with the net heat exchange assumed to be into the system and the net work assumed to be out of the system. If no mass crosses the boundary, but work and/or heat do, then the system is referred to as a “closed” system. If mass, work and heat do not cross the boundary (that is, the only energy exchanges taking place are within the system), then the system is referred to as an isolated system. Isolated and closed systems are nothing more than specialized cases of the open system.
