The continuous formation and development of a laminar vortex street behind a circular cylinder of radius D in a flow of velocity U∞ has been modeled as a Huygens‐type wave process, where the transverse velocity Uy and the vorticity ω in the near

The force field around a circular cylinder (D = 5.1 cm) towed at U = 0.15 m/s was explored by measuring the lift Fl and drag Fd of a small (cylindrical) probe inserted at various locations near the cylinder. By taking the Fourier transform of the lif

Sound waves of frequency ƒ o and wavelength λ o ⪢ R resonantly excite the fundamental mode of azimuthal waves on eddies of radius R . This generates standing waves on the rotating eddies at the frequency αƒ o , resulting in a fluctuating pressu

Flow visualization experiments with stripped dye markings show that the vortices in the wake of an impulsively started circular cylinder initially form with random phase along the span. In successive vortex generations, small perturbations disappear

The initial configuration of a vortex street behind an impulsively started cylinder in a towing tank is usually subject to small‐scale perturbations in the flow. It was found that the presence of a trigger plate, mounted normal to the towing direct

In the presence of methanol at concentrations up to 12% by volume, photosynthetic fixation of C14O2 into glycolic acid, glycine, alanine, serine, and an unknown compound proceeds at nearly normal rates over periods of 1 to 8 minutes. However, fixatio
