Abstract
This paper is concerned with aspects of gasoline spray droplet impingement simulation, for which an improved model has been developed for predicting the outcomes of spray droplets impacting on a wall. The model is assessed by simulating experiments on oblique spray impingement in a wind tunnel. This is done with the aid of a specially-devised procedure for deducing the specification of initial droplet sizes and velocities at the gasoline injector from downstream measurements. The calculated wall spray characteristics show favourable agreement with the measurements. INTRODUCTION Spray impingement on walls occurs in a wide range of situations. These include various types of reciprocating engines, gas turbines, spray cooling systems, ink-jet printing and many other applications in agriculture and medicine. In small high speed direct-injection Diesel engines, the fuel is directly injected into the compact chamber at a high speed and strikes the walls due to short free spray path. I...
