Abstract

A sufficient large taper angle nozzle fitted with a swirl injector proved to provide a robust side-opened spray of which structure is less influenced by the change in the surrounding air pressure and temperature. Nevertheless, the mass distribution of the injected mass is not uniform and it has a distribution that depends on the taper angle and the flow angle. Analysis has been performed to calculate the mass distribution which is a necessary initial condition for spray modeling. The side-opened angle was evaluated for different nozzle taper angles. The derived equation of mass distribution requires previous knowledge of nozzle exit film thickness and flow angle, which were measured experimentally
