    Notes: [Auszug] YOUR correspondent, Mr. E. Kilburn Scott, suggests in NATURE of November 24, p. 760, that “the ball may be a mass of concentrated nitrogen oxides,” and considers that this would “fit in well with the formation and action of such gases,” and he compares the chemical activity of lightning with ...

    Notes: [Auszug] THE question—What chemical changes, if any, are associated with atmospheric electrical discharges ?—does not appear hitherto to have received a definite answer. Nitrogen peroxide and ozone are both referred to in scientific literature, although neither appears to have been satisfactorily ...

    The effects of rotation on initially anisotropic homogeneous flows (1991)
    New York, NY : American Institute of Physics (AIP)
    Physics of Fluids 3 (1991), S. 2421-2425 
    Details
    ISSN: 1089-7666
    Source: AIP Digital Archive
    Topics: Physics
    Notes: Rotation of initially anisotropic homogeneous flows is studied using a model spectral tensor. It is shown that the anisotropy changes because of the influence of rotation through phase scrambling. Phase scrambling causes the Reynolds stresses to develop with damped oscillations. The final Reynolds stress anisotropy is found to be proportional to the initial structural tensor anisotropy. Closure models for the rapid pressure strain terms should reflect this change in anisotropy, and should drive the anisotropy to reach its final predicted state. Finally, it is shown that long-time integration using direct numerical simulations should be treated with care because phase scrambling effects on a discrete wave space can cause loss of resolution when time becomes large.

    A spectrum model for weakly anisotropic turbulence (1990)
    New York, NY : American Institute of Physics (AIP)
    Physics of Fluids 2 (1990), S. 1500-1502 
    Details
    ISSN: 1089-7666
    Source: AIP Digital Archive
    Topics: Physics
    Notes: A simple model, parametrized by the Reynolds stress anisotropy, is proposed for the spectrum of weakly anisotropic turbulence. It contains a model constant that affects its region of realizability. This spectrum model is used to derive a one point closure to the rapid pressure-strain term. The derived pressure-strain model is linear in the Reynolds stress anisotropy and is of the same form as the closure model of Launder, Reece, and Rodi (LRR) [J. Fluid Mech. 68, 537 (1975)]. The spectrum model becomes unrealizable in some regions of wave space for sufficiently large anisotropy of the Reynolds stress, and this is used to infer the region of validity of the linear closure model. It is found that the extent of the valid region is very small when the model constant is set to match rapid distortion theory, and largest for a model constant set close to the value suggested by LRR. However, even the largest valid domain does not extend very far from isotropy, suggesting inherent weakness in the linear pressure-strain models.

    Notes: [Auszug] IF electrostatic measurements are made in the air on a bridge over the permanent way near any railway station, extraordinarily large positive charges given off by steam locomotives will be observed, especially on starting up. These positive charges are carried by the wind for long distances. ...

    Notes: [Auszug] THE only reason advanced by Dr. Chree (NATURE, April 11, p. 531) in support of his contention that smoke is responsible for atmospheric electricity in towns, is the fact that atmospheric pollution is worst when the potential gradient is abnormally high.
