 SHE Level 5 SCQF Credit Points 15.00 ECTS Credit Points 7.50 Module Code MMH323561 Module Leader Don McGlinchey School School of Computing, Engineering and Built Environment Subject Mechanical Engineering Trimester A (September start)

### Summary of Content

This module combines advanced theory of fluid flow and heat transfer with numerical methods as applied in computational fluid dynamics (CFD). The uses and limitations of CFD are discussed in context and a commercially available CFD package is used to solve engineering problems and the solutions are evaluated.

### Syllabus

Fluid Mechanics. Non-Newtonian Flow: Fluid classification, model fluids, power law fluids, time-dependent behaviour, laminar flow, velocity profiles, viscometers, turbulent flow, friction factor, generalised equations of flow. Compressible Flow: Governing equations: velocity of sound, isentropic conditions, Mach number, steady isentropic flow, non-parallel sided ducts, convergent-divergent ducts and orifices, stagnation conditions, Laval nozzle, normal shock wave in diffuser, Fanno flow - compressible flow in a duct, isothermal flow in pipes. Thermodynamics. Heat Transfer: Revision of one-dimensional conduction heat transfer theory and applications, Fourier's law of conduction, thermal conductivity, Newton's law of cooling, heat transfer coefficient. Extended surfaces, straight fins: long, short - distinguishing criteria; Biot number. Computational Fluid Dynamics. Conservation laws of fluid motion and boundary conditions. Differential and integral forms of the general transport equations. Turbulence and it's modelling. The finite volume method for convection - diffusion problems. The central differencing scheme. Solution algorithms for pressure - velocity coupling. Introduction to CFD software; pre-processor, solver and post-processor. CFD analysis examples of heat and fluid flow; closed system, pipe system, open flow system. Convergence and stability. Evaluating a CFD analysis and validating results. Advanced topics and applications, for example, combustion modelling, multi-phase flows, non-Newtonian fluid flows, heat transfer.
