  1. Institute of Thermal Machinery al. Armii Krajowej 21, 42-200 Czestochowa, Poland www.imc.pcz.czest.pl Areas of interest • Energy and Aero Priorities • Mathematical modelling of flows in blade system of rotating machinery • Modelling of free flows, jets and wakes in aeronautical industry • Modelling of flow and electrochemical phenomena in fuel cells • Modelling of complex thermal systems in power engineering • Modelling of aerodynamics, heat and mass transfer in gas-solid particles flows • Renewable fuels • combustion modeling of aeroengine combustor and aircraft wake/engine jet interactions (prof. A. Boguslawski) • wall transitional flow modeling in aeroengine gas turbine bladings and turbulent boundary layer simulations (prof. W. Elsner).

  2. Areas of interest - Modeling of aeroengine combustion chamber MOLECULES(5th FP) - Elaboration of modern software tools ( CFD ) for calculations and simulations of flows and combustion processes proceeding inside combustion chambers of aeroengines INTELLECT - 6th Framework Programme of UE. Elaboration of numerical models of modern aeroengines TIMECOP-AE(6th FP) –Toward Innovative Methods for Combustion Prediction in Aero-Engines Bilateral project VrijeUniversiteit of Brussels - Czestochowa University of Technology „Modeling of turbulent flows with combustion by Large Eddy Simulation in connection with Conditional Moment Closure model” COST Action P20 LES-AID Large-Eddy Simulation for Advanced Industrial Design

  3. UTAT Investigation of aeroengine aerodynamics Areas of interest - TRANSPRETURB Thematic Network(5th FP) – upgrading of current industrial CFD capabilities, defining requirements for further RTD model and transition model development UTAT(5th FP)- Understanding of mechanisms of blade-rowinteractions as well as unsteady laminar-turbulent transition process in axial-flow turbines Bilateral project Ghent University - Czestochowa University of Technology „Turbulence and transition modelling methods in turbomachinery applications” Aircraft aerodynamics Areas of interest - FarWake(6th FP) – interaction of vortices with airplane for Airbus WallTurb(6th FP) – basic research on turbulent boundary layer affected by adverse pressure gradientfor Airbus

  4. Experimental Facilities, Equipment and Software open-loop wind tunnels • turbine bladings - rotor simulator • environmental aerodynamics • heated jets • countercurrent / heated jets Computational resources • Procesor type: Dual-Core AMD Opteron 8214, Number of processors 8 (number of nodes 16) 32 GB RAM • Fluent, Gambit • academic codes • unNEWT+PUIM (Cambridge) • Sparc (Karlsruhe) • BOFFIN (Imperial College) • SAILOR (IMC Częstochowa) • Procesor type: Dual-Core AMD Opteron 8222, Number of processors 8 (number of nodes 16), 64 GB RAM Software tools

  5. Spark ignition of the methane jet: BOFFIN-LES solver with Eulerian PDF method • jet velocity 12.5 m/s • spark on the jet axis: 10D, 30D, 40D, 50D • spark radius 2.5 mm, Gaussian shape SPARK LES+PDF Experiment Animation 5

  6. SPARK 10mm Animations correspond to ignition at this location Animation (unsuccessful ignition) SPARK 15 mm Animation (successful ignition) Modelling of the spray ignition: animations illustrating unsuccessful and successful ignition process Initial spark temperature growth Spark is modelled by adding the source term in the enthalpy equation. 6

  7. Spark View of the instantaneous droplets distribution and spark kernel just after ignition. Animation Modelling of the spark ignition and light acrossusing BOFFIN code • Due to extremely time consuming simulations for threesector configuration the spark parameters (location and size) are chosen such to guarantee successful ignition in selected sector. • Basing on previous experiments performed for single sector case the spark was located close to the edge of the recirculation zone, the size of the spark was equal to 15 mm. • Three-steps solution procedure: (cold flow  spray  ignition (flame propagation)) took more than 3 months, this corresponds to less than one second of real life ! View of the instantaneous axial velocity before ignition. Blue colour denotes negative velocity (recirculation zone). 7
