Exclusions
Description The aim of the module is to provide an introduction to transport phenomena (momentum transfer and heat and mass transfer) as well as associated engineering applications.

Syllabus

Fluid Flow: a) Introduction to fluid flow phenomena in engineering.
b) Hydrostatics: Pressure variation with position in a static fluid, manometers, hydrostatic forces on submerged surfaces, forces on unconstrained bodies, surface tension and capillarity, methods of surface tension measurement.
c) Hydrodynamics: classification of flows in terms of variation of flow parameters in time and space, the concepts of streamline and stream tube, the principles of continuity, energy and momentum, turbulent flow.
d) Applications of principles to engineering problems, including flow measurement (e.g by orifice, Venturi, rotameter). Forces on pipe bends, nozzles and plates.
e) Steady flow problems concerning head loss and pressure drop due to friction in pipe flows (Bernoulli), non-circular ducts, friction factors, Moody diagram and friction losses in fittings.
f) Physical fluid properties, their dimensions and units, SI System, dimensional analysis.

Heat and mass Transfer: a) Conduction/Diffusion: (one-dimensional steady state) Fourier’s and Fick’s Law, conduction with multiple layers, simple geometries, resistance in series.
b) Convection and Boundary Layers: Heat and Mass transfer coefficients for natural and forced convection. Practical problems involving forced convection, resistances in series, overall transfer coefficients, Design of simple exchangers, log-mean differences.
c) Basics of radiation: (Stefan-Boltzmann equation), emissivity, absorptivity, transmissivity and reflectivity, net exchange of radiation between surfaces.
Learning Outcomes By the end of the module students should be able to:
  • Knowledge and understanding of scientific principles and methodology necessary to underpin their education in mechanical and related engineering disciplines, to enable appreciation of its scientific and engineering context and to support their understanding of future developments and technologies
  • Knowledge and understanding of mathematical principles necessary to underpin their education in mechanical and related engineering disciplines and to enable them to apply mathematical methods, tools and notations proficiently in the analysis and solution of engineering problems.
