Foppl’s stability analysis (1913) of the equilibrium positions of a line vortex pair in the downstream neighbourhood of a circular cylinder in the two-dimensional potential flow of an incompressible fluid moving with uniform speed at infinity has b

The plane ballistic trajectories followed by small spherical particles representing a variety of spores ejected into still air are determined for motion in a constant gravitational field and resisted according to the Stokes law of viscous friction. T

SUMMARY The movement of dust seeds, spores and pollen released into winds which fluctuate in both speed and direction is considered in terms of the aerial mechanics of a small spherical particle moving under the Stokes' law of resistance and in a gra

SUMMARY Seeds and fruits of widely differing sizes and shapes and which employ different flight styles in wind-borne movement during dispersal are discussed qualitatively in general aerodynamic terms, and grouped according to aerodynamic rather than

SummaryThe mean flow of an incompressible fluid in a straight suction duct with porous walls is considered and relations between the inflow and the pressure difference required to produce it are established on the basis of an elementary momentum anal

SUMMARY The aerial paths described by plumed seeds shed from motionless plants and moving in steady horizontal winds with vertical convection currents are discussed and formulae established for calculating them both roughly and fairly accurately. Mos

SummaryThe momentum analysis of the mean flow of an incompressible fluid in a straight suction duct with porous walls dealt with in a previous paper is extended to account for deflection of the inflow towards a direction parallel with the axis of the

The movement of variously dense spherical particles representing a variety of seeds, fruits, spores and pollen, and released from rest into arbitrary winds and a gravitational field is discussed in general terms that account in detail for changes in
