Breakup Characteristics of a Newtonian Liquid Sheet Formed by a Doublet Impinging Jet Injector

The breakup characteristics of a plane fluid sheet flowing in a gaseous atmosphere is considered theoretically for Newtonian liquids. Several approximations belonging to hydrodynamic parameters are conducted to determine the influence of fluid properties on the breakup process. Experimental data is obtained by spray experiments with a like-on-like impinging jet injector setup and compared to the theoretical results concerning critical wave lengths and breakup lengths. The experiments show a good agreement to an introduced approximation method in the case of high viscous liquids.
