# Introductory Thermofluids (AMME2200)

## UNIT OF STUDY

This unit of study aims to give students a practical, introductory course in Fluid Mechanics, Heat Transfer and Thermodynamics. Students will become familiar with the basic principles in these areas, they will learn to recognize the types of Thermofluids problems which engineers face and they will learn how to obtain solutions.
Fluid Mechanics
Properties: viscosity, surface tension, cavitation, capillarity. Hydrostatics: manometers, forces and moments on submerged surfaces, centre of pressure, buoyancy, vessel stability, metacentre. Flow: Streamlines, turbulence, continuity, Bernoulli, venturi meter, pitot tube, head, loss coefficients, pumps, turbines, power, efficiency. Fluid momentum, drag, thrust, propulsive efficiency, water jump, wind turbine, turbomachinery, Euler equation, torque, power, head, Francis, Pelton, Kaplan turbines. Dimensional analysis: Similarity, scale modelling, Buckingham pi theorem, turbulence, Reynolds No. Pipe flow: Laminar, turbulent, pressure drop, Moody chart.
Heat Transfer
Conduction: thermal circuits, plane, cylindrical, conduction equation, fins. Heat Exchangers: LMTD and NTU methods. Unsteady Conduction: lumped capacity, Bi, Fo, Heissler charts. Convection (forced), analytical Nu, Pr correlations. Convection (natural) Ra, Gr. Radiation spectrum, blackbody, emissivity, absorptivity, transmissivity, Stefan-Boltzmann, Kirchhoff Laws, selective surfaces, environmental radiation.
Thermodynamics:
1st Law of Thermodynamics, cycle analysis. Properties; State postulate, ideal gases, 2-phase properties, steam quality. Turbines, compressors.
