    3. 3 1995, Dipl. -Ing. Mech. Eng. (Process Tech.) University of Maribor 1998, M.Sc. Nuclear Eng. University of Ljubljana 2001, Ph.D. Nuclear Eng. University of Ljubljana 2002, M.Sc. Mech. Eng. (Fluid Mechanics & Heat Transfer) University of California, Los Angeles

    4. 4 More than 10 years of intensive CFD related experience: R&D of numerical methods and their implementation (convection schemes, LES methods, semi-analytical methods, Reynolds Stress models) Design analysis (large heat exchangers, small heat sinks, burners, drilling equip., flash furnaces, submersibles) Fire prediction and suppression (backdraft, flashover, marine environment, gas releases, determination of evacuation criteria) Safety calculations for nuclear and oil industry (water hammer, PSA methods, severe accidents scenarios, pollution dispersion)

    5. 5 As well as CFD, experiences also in: Experimental methods QA procedures Standardisation and technical regulations Commercialisation of technical expertise and software products

    6. 6 Overview of fluid dynamics transport equations - transport of mass, momentum, energy and composition - influence of convection, diffusion, volumetric (buoyancy) force - transport equation for thermal radiation Averaging and simplification of transport equations - spatial averaging - time averaging - influence of averaging on zone and field models Zone models - basics of zone models (1 and 2 zone models) - advantages and disadvantages

    7. 7 Field models - numerical mesh and discretisation of transport equations - turbulence models (k-epsilon, k-omega, Reynolds stress, LES) - combustion models (mixture fraction, eddy dissipation, flamelet) - thermal radiation models (discrete transfer, Monte Carlo) - examples of use Conclusions - software packages Examples - diffusion flame - fire in an enclosure - fire in a tunnel

    8. 8 Today, CFD methods are well established tools that help in design, prototyping, testing and analysis The motivation for development of modelling methods (not only CFD) is to reduce cost and time of product development, and to improve efficiency and safety of existing products and installations Verification and validation of modelling approaches by comparing computed results with experimental data are necessary Nevertheless, in some cases CFD is the only viable research and design tool (e.g. hypersonic flows in rarefied atmosphere)
