# ING2044 Thermodynamics and Fluid Mechanics

## Course description for academic year 2019/2020

### 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.
- Can use thermodynamics 1st and 2nd law for simple closed and open systems.
- Can explain thermodynamic state diagrams.
- Can explain various properties of liquids and specify their technical impact.
- Can set up equations to describe the pressure variation in hydrostatic fluids.
- Can apply Archimedes principles for solving problems.
- Can describe characteristics of laminar and turbulent flow.
- Knows the basic equations for fluid flow-- such as conservation of mass, conservation of momentum, conservation of energy-- and can set up these equations to solve the problems.

-Skills

The student can

- Calculate heat and work for different types of processes.
- Use thermodynamics 1st and 2nd law to calculate basic processes in thermodynamics.
