THERMAL ENGINEERING PRE-REQUISITE: Knowledge of elementary calculus and Partial derivations.
Faculty : Dr. R. Udaya kumar
OBJECTIVE: Student will be exposed to the construction, working and thennodynamic analysis of reciprocating air compressors and also systems ofIC engines and Refrigeration and air-conditioning.
1. LAWS OF THERMODYNAMICS (7)
Basic concepts - first law of thermodynamics applied to closed and open systems - simple problems.
2. THERMODYNAMIC CYCLES AND I.C. ENGINES (8)
Second law of thermodynamics - concept of reversible process
Air standard cycles - otto, diesel and dual cycles - I.C. engines, S.I. engines & CI engines
3. COMPRESSOR AND TURBINES (8)
Reciprocating compressor - effect of clearance volume, single and multistage compressor - Volumetric efficiency - calculation of power requirement - gas turbines - open and closed cycle - intercolling, reheating and regenerative cycles Wankel engine-Sonic velocity, mach no. Wave propagation - mach cone, static and stagnation property relations, isotropic flow, use of gas tables, normal shock, flow through converging and diverging nozzle
4. Properties of steam (8)
P – V, T - S and H - S diagrams- Rankine cycle, modifications to improve thermal efficiency - psychrometrics - various a/c processes - systems - refrigeration - Bell coleman and vapor compression cycles - vapor absorption cycle.
