Abstract

The flow field of gelled fuels incylindrical and slightly conical tubes has been investigated by means of analytical and numerical calculations and assumptions. The rheological properties of these shear thinning fluids can be described in the medium shear rate range by a power-law function. Numerical calculations of the flow field and pressure losses in a tapered injector are presented and compared with analytical assumptions. To describe the fluid flow behavior also in the low shear rate range, the power-law equation has been expanded by a yield stress, which liads to a plug flow regime in the core range of tube flows.
