โœฆ Synopsis


Analyses of the influence of vortical structures on a two-density fluid indicate a possible motion of the light fluid into the heavy one and vice versa. Various simplifying assumptions including that of an inviscid have been made in this report, but the results provide an insight into the fast burning observed along vortex tubes. The analysis is a contribution to our understanding of the hydrodynamics aspect of turbulent combustion; it could also be useful in modeling turbulent premixed combustion. No limits have been placed on the scales of the vortical structures. Our estimates of the induced axial velocities (the burst) are valid for any combination of two fluids (i.e. for any thermal expansion ratio) thereby making them more acceptable than previous estimates by Chomiak and by Daneshyar and Hill [2].

The evolution of a premixed flame under conditions of confinement is studied theoretically. The analysis is based on a hydrodynamic model in which the flame is treated as a surface of discontinuity. The flame structure is assumed to be quasi-steady with a high activation energy and a large heat rele

An optical study has been made of the thermal ignition of a mixture containing 16.7 per cent methane and 83.3 per cent oxygen in the temperature range 520 ยฐ to 750ยฐC and at a total pressure of 600 torr. Ignition was observed to commence in the gas phase at a point close to the centre of the cylindri

The steady propagation of a premixed laminar flame in circular tubes with adiabatic wall and isothermal wall is numerically investigated in the present study. It is assumed that the flow is axisymmetric and the flame chemistry is modeled by an one-step overall reaction which simulates the reaction o
