Interaction of a burning gas jet with a permeable rotating barrier

Abstract

The interaction of a carbon-dioxide jet and a burning propane-butane jet with a rotating disk prepared from a cellular porous nickel highly permeable to gases has been experimentally studied. Visual pictures of the flow pattern and the spatial distributions of gas concentrations and temperatures were obtained. Modeling of the fuel mixing with air using carbon dioxide has shown that there exists a certain correlation between the initial distribution of CO₂ concentrations and the distributions of temperatures and propane-butane combustion product components. It is shown that the burning of a propane-butane mixture on the disk is accompanied by the heating of the disk surfaces to 800–900 °C. The steady burning modes are identified versus the rate of fuel consumption, the disk-to-nozzle separation, and the speed of disk rotation.
