Kurzfassung

The spray behavior of different gelled fuels based on Jet A-1, has been investigated in two different atomizer types, i.e. an air blast atomizer with an annular coaxial air flow and a doublet like-on-like impinging jet atomizer. The characteristics of the jet breakup process of both injector types have been visualized by means of the shadowgraph technique. For the air blast atomizer different breakup regimes have been observed with increasing momentum flux ratio for the 3 investigated fuels. For the impinging jet atomizer the formation of a gel sheet has been observed, which is located at the intersection point of both gel jets and which is perpendicular oriented to the injector plane. Also the flow behavior in cylindrical and slightly conical tubes of gelled fuels, whose viscosity is shear rate dependent, has been described with analytical assumptions.
