HEAT ENGINE - Thermodynamics:
HEAT ENGINE. A heat engine is a thermodynamics system that operates in a cycle in which heat can be transferred from heat source to heat sink. For the continuous production of work. Both heat and work interaction takes place across the boundary of engine. It receive heat Q1 from a higher temperature reservoir at T1.
It converts part of heat Q1 into mechanical work W1. It reject residual heat Q2 into sink at T2. There is working substance that continuously flows through the engine to ensure continuous/cyclic operation.
