The present disclosure relates to a bicycle frame and associated bicycle components, and to reducing the aerodynamic drag of these. In one aspect, there is provided an elongate structural member of a bicycle frame, the member comprising a lengthwise extending leading edge, the leading edge comprising at least a pair of forwardly extending protrusions spaced apart lengthwise therealong. In one form, the protrusions comprise tubercles, a series of which are spaced apart lengthwise along the leading edge, and which further extend to at least one side of the leading edge so as to transition into a chordwise extending rib.

Aerodynamics of bicycle frames and associated components

Interaction between two different species of particles in a fluid stream is promoted by generating turbulent eddies in the fluid stream. The turbulent eddies are designed to be of such size and/or intensity that the two species of particles are entrained into the eddies to significantly different extents. Consequently, the different species of particles follow different trajectories, and the likelihood of collisions or interactions between the particles is increased. Optimum collision rates will occur for a system which maintains a Stokes Number (St) much less than 1 for one species, and or order 1 or greater for the other species. The invention has particular application in air pollution control, by promoting agglomeration of fine pollutant particles in air streams into larger particles to thereby facilitate their subsequent removal from the air streams.
