  2. 11. Studies in Robotic Vision, Optical Illusions and Nonlinear Diffusion Filtering

    Author : Henrik Malm; Matematik LTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; hand-eye calibration; camera calibration; nonlinear diffusion filtering; robotic vision; optical illusions; Mathematics; Matematik;

    Abstract : This thesis is divided into three parts, which all deal with computational analysis and processing of images. However, the settings are quite diverse.They range from robotic camera sensors, over human perception, to physical measurement setups. READ MORE

  4. 12. Numerical Study of Cellular Instability in Burner Stabilized Adiabatic Laminar Premixed Flames

    Author : Jiangfei Yu; Strömningsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Detailed Numerical Simulation; Cellular premixed flame; Hydrogen; Oxy-fuel; Heat-flux burner; Hydrodynamic instability; Diffusive-thermal instability; Nonlinear flame dynamics.;

    Abstract : The thesis deals with experiments and numerical simulations of adiabatic laminar premixed flames anchored to a heat-flux burner using different mixtures under various operating conditions. The aim is to obtain a better understanding of cellular instability in heat-flux burner anchored flames. READ MORE

  5. 13. Flamelet modelling of soot formation in diffusion flames

    Author : Anne Simone Dederichs; Avdelningen för Brandteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; Emissions; Pollution; pollution control; Miljöteknik; kontroll av utsläpp;

    Abstract : In this work the steady and unsteady flamelet models have been applied to soot formation in laminar and turbulent diffusion flames. The aim was to study how different model parameters affect soot formation in diffusion flames. It was shown that certain assumptions are more crucial in laminar diffusion flames than in turbulent ones. READ MORE

  6. 14. Laser-Based Combustion and Trace-element Analysis

    Author : Yvonne Malmsten; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; laser-induced fluorescence; graphite furnace; trace element analysis; LEI; laser-enhanced ionisation; LIF; meta-stable; flow-tagging; NO; OH; counter-flow diffusion flame;

    Abstract : Laser spectroscopy has been utilised as a tool for combustion diagnostics and sensitive trace-element analysis. In the field of combustion analysis, a characterisation of a CH4/N2 - O2/N2 counter-flow diffusion flame has been performed using Laser-Induced Fluorescence (LIF). READ MORE

  7. 15. Experimental studies of turbulent flames at gas turbine relevant burners and operating conditions

    Author : Xin Liu; Förbränningsfysik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbulent Combustion; Gas Turbine; Laser diagnostic; Fuel flexibility; Plasma-assisted combustion; Ammonia flame; High pressure;

    Abstract : With the increasing demand of using alternative and renewable fuels, it becomes of vital importance to consider the fuel flexibility when designing a new burner for gas turbines. Hydrogen-enriched fuel and ammonia are two of these potential fuels, and they can significantly change the operability range of the gas turbines. READ MORE
