# Introductory Thermofluids - AMME2200

Year - 2020

Thermofluids is made up of the components Fluid Mechanics, Heat Transfer and Thermodynamics and it reaches into all areas of Engineering including issues of human comfort, power generation and environment. A broad range of essential topics is covered in this unit, suitable for students who have not already completed similar component units. The emphasis is on analysis and problem solving (detailed calculations) by application of the relevant basic principles to typical engineering problems. Fluid Mechanics Properties: viscosity, surface tension, cavitation, capillarity. Hydrostatics: manometers, forces & moments on submerged surfaces, centre of pressure, buoyancy, vessel stability. Flow: Streamlines, turbulence, continuity, Bernoulli, venturi meter, pitot tube, head, loss coefficients, pumps, turbines, power, efficiency. Fluid momentum, drag, thrust, propulsive efficiency, wind turbines, turbomachinery, torque, power, head, Francis, Pelton, Kaplan turbines. Dimensional analysis, similarity, scale modelling, Reynolds No., pipe flow, 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, Properties, State postulate. Ideal gases, 2-phase properties, steam quality. Turbines, compressors. thermal efficiency and COP for refrigerators. 2nd Law of Thermodynamics, Kelvin-Planck, Clausius statements. Carnot engine. Entropy; increase of entropy principle, entropy and irreversibility. Isentropic processes, T-s diagrams, isentropic efficiency. Some power and refrigeration cycle analysis, characteristics of main power cycles. Psychrometry, air-conditioning, thermal comfort basics.
