Kurzfassung
The flow and spray behavior of various gelled fuels, which are non-Newtonian shear-thinning fluids, is presented and compared. The present publication gives an overview about rheological properties, some aspects of the flow characteristics and of the atomization behavior of investigated gels with a doublet like-on-like impinging jet injector. Different breakup modes were observed in dependence of the jet exit velocity on the obtained shadowgraph images. Furthermore they are presented in a regime diagram with the generalized Reynolds number and the Weber number as parameters. Additionally a first attempt will be given to correlate both Newtonian and gelled fluids in a common regime diagram.
