Experimental investigation on behavior of diesel spray after interference with a circular cylinder 2019-01-2285

A glow plug is the promising way for improvement for ignition of fuel under cold start condition in high-speed diesel engines. The configuration of a glow plug and a diesel spray in a combustion chamber is important factor to maintain ignitability of fuel at cold start. In this study, flow structure of the spray interfered with a circular cylinder instead of the glow plug was investigated by changing of location of the circular cylinder with respect to the spray. As results, the vortex around the circular cylinder was formed with interference of the spray with the circular cylinder, and appearance position of its vortex was related to interference position of the spray periphery with the circular cylinder was clarified.
