Development of a turbulence scale controllable burner and turbulent flame structure analysis

A turbulence controllable premixed turbulent Bunsen burner was developed to study the separate effects of turbulence intensity and integral scale on the premixed turbulent flame. Circular and slot perforated plates with adjustable plate positions were designed to produce quasi-isotropic and uniform turbulence field containing scale-expanded vortices with normalized turbulence intensity ranging from 5% to 40%. The method to attain the controlled...
