BEE305 THERMAL ENGINEERING

OBJECTIVE : To promote understanding of the basic principles of Thermodynamics and their applications in the analysis of Heat Engines, air compressors and Refrigeration systems.


1. BASIC THERMODYNAMICS:

Defnitions of system- open, closed, isolated, system boundary, property, process, cycle, heat, work, reversible and quasistatic processes- Different types of processes- calculation of work done during a process.


2. FIRST LAW:

Closed system application- internal energy- heat transfer calculations- open system application- flow work- enthalpy- steady flow energy equation for boilers- condensers- Turbines- compressors- evaporators- nozzles- throttling process.


3. SECOND LAW:

Kelvin - Planck statement- Clausing statement- their equivalence- Carnot cycle- Clausius inequality- entropy- calculation of entropy change- TS diagram- vapour compression refrigeration cycle.


4. RECIPROCATING MACHINES:

Reciprocating air compressors- optimum pressure ratio in multistage compression- inter cooling- effect of clearance volume- performance and testing of I.C. engines.

5. VAPOUR POWER CYCLE:

Rankine cycle- reheat cycle- regenerative cycle- calculations for efficiency and power output using steam tables and Mollier chart.
