  • free swimming daphnia pulex can avoid following Stokes Law
    Limnology and Oceanography, 1996
    Co-Authors: Patrick R Gorski, Stanley I Dodson
    Abstract:

    The swimming behavior of Daphnia pulex was compared between two temperatures (5 and 25°C), with two acclimation protocols, using three-dimensional video techniques. Our hypotheses, based on Stokes' Law and metabolic considerations, predicted large changes in swimming behavior. However, free-swimming individuals did not follow Stokes' Law. They sank slower than predicted, having increased their sinking rate by ∼23% from 5 to 25°C. Anesthetized Daphnia followed Stokes' Law, showing an increase in sinking rate of 70% over the temperature range. The Q 10 values of all swimming behaviors were between 0.91 and 1.11 (which are significantly less than Q 10 values for metabolic rates) and were nearly uniform over a 20°C range. Our results also indicate that acclimation to different temperatures for 1 h is sufficient to minimize acclimation effects.

  • experimental validation of the Stokes Law at nonisothermal conditions
    Physics of Fluids, 2002
    Co-Authors: Ezra Barziv, Bin Zhao, Elaad Mograbi, David Katoshevski, G Ziskind
    Abstract:

    Novel experimental results on the hydrodynamic forces acting on a small heated particle at low Reynolds and Grashof numbers are presented. The temperature difference between the particle and the ambient causes free convection flow around the particle. As a result, the drag force exerted on the particle by forced flow deviates significantly from the Stokes Law. This deviation is represented quantitatively for three basic directions of forced flow, namely assisting, opposing, and crossing with respect to free convection flow. Validity of the Stokes formula at mixed-convection creeping flow conditions is discussed.
