ING2044 Thermodynamics and Fluid Mechanics

Contents and structure

The two main topics are taught separatly, with their own compulsory work and exam.

Thermodynamics: work and heat, the first law of thermodynamics , working medium (ideal gas/water/refrigerants), phase diagram, reversible and irreversible processes, second law of thermodynamics, entropy, combustion, thermodynamic cycle (Carnot, Otto, Diesel, Rankine, gas turbine), cooling processes.

Fluid mechanics: fluid properties, buoyancy, flow of ideal fluids, laminar flow, turbulent flow, conservation of mass, conservation of energy (Bernoulie's theory), conservation of momentum, friction in one pipe, cavitation in a pump.

Learning Outcome

 -Knowledge:

The student

• Can explain thermodynamic terms, quantities and functions.
