    Observations of the frequencies in a sphere wake and of drag increase by acoustic excitation (1988)
    [S.l.] : American Institute of Physics (AIP)
    Physics of Fluids 31 (1988), S. 3260-3265

    Topics: Physics
    Notes: Vortex shedding and instability wave frequencies have been measured in the wakes of spheres in the Reynolds number range 500〈Re〈60 000. The effect of acoustic excitation was examined and an interaction between the two frequency modes was found at the lower Reynolds numbers; through this interaction, external forcing at the instability frequency could change the vortex shedding frequency. The development of the mean wake was manipulated by forcing near to the dominant shear layer instability frequency. With this forcing, the separated shear layer moved closer to the surface of the sphere and the reversed flow region of the wake was shortened. Concomitantly, the base pressure decreased and drag increased.

    Free-streamline analysis of deformation and dislodging by wind force of drops on a surface (1988)
    [S.l.] : American Institute of Physics (AIP)
    Physics of Fluids 31 (1988), S. 43-48 
    Details
    ISSN: 1089-7666

    Topics: Physics
    Notes: Free-streamline theory is used to analyze the deformation and dislodging by wind pressure of drops of liquid adhered by surface tension to a solid surface. The critical Weber number for droplets to be dislodged is determined as a function of advancing and receding contact angle. Graphical results for drop shape are in good agreement with observation.

    On modeling three-dimensional turbulent wall layers (1993)
    New York, NY : American Institute of Physics (AIP)
    Physics of Fluids 5 (1993), S. 1231-1238 
    Details
    ISSN: 1089-7666
    Source: AIP Digital Archive
    Topics: Physics
    Notes: A Reynolds stress model with a modification to the ε equation is shown to reproduce the essential new features observed by Moin et al. [Phys. Fluids A 2, 1846 (1990)] in three-dimensional turbulent channel flow. Perhaps the most significant of these features is an initial drop of turbulent kinetic energy; previous turbulence models do not predict this. The effect of the three-dimensional modification on the infinite swept-wing boundary layer is assessed. It is not large and is primarily restricted to a region near to the surface. A three-dimensional homogeneous shear flow is formulated and turbulence statistics are computed by solving a simple Reynolds stress model.

    Eddy viscosity transport model for turbulent flow (1994)
    [S.l.] : American Institute of Physics (AIP)
    Physics of Fluids 6 (1994), S. 1007-1015 
    Details
    ISSN: 1089-7666
    Source: AIP Digital Archive
    Topics: Physics
    Notes: An eddy viscosity transport model that is integrable to no-slip walls is described. The transport equation accommodates significant departure of the turbulence from equilibrium. The model uses an elliptic relaxation equation to avoid a need for damping functions; nonlocal wall effects are produced by solving the elliptic equation. Length scales are determined locally, without reference to distance to a surface. The model bifurcates from a laminar to a turbulent solution at a reasonable critical Reynolds number in plane channel flow. An assessment of the model is provided via boundary layer computations: these show that it behaves well in zero and adverse pressure gradients, although premature separation occurs in a strong adverse pressure gradient. Good results are obtained for the trailing edge separation bubble of an aerofoil at large angle of attack.

    An anemometer for highly turbulent or recirculating flows (1987)
    Springer
    Experiments in fluids 5 (1987), S. 184-188

    ISSN: 1432-1114
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Abstract An anemometer which determines flow velocity by ionizing air and sensing the convective displacement of the ions is described. It is suited to measurement in low speed, highly unsteady gas flows. Comparisons to hot wire spectra suggest the corona anemometer has adequate frequency response to make it a useful tool for fluid dynamics measurement.

    Near-wall turbulence closure modeling without “damping functions” (1991)
    Springer
    Theoretical and computational fluid dynamics 3 (1991), S. 1-13 
    Details
    ISSN: 1432-2250

    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics , Physics
    Notes: Abstract An elliptic relaxation model is proposed for the strongly inhomogeneous region near the wall in wall-bounded turbulent shear flow. This model enables the correct kinematic boundary condition to be imposed on the normal component of turbulent intensity. Hence, wall blocking is represented. Means for enforcing the correct boundary conditions on the other components of intensity and on the k — ɛ equations are discussed. The present model agrees quite well with direct numerical simulation (DNS) data. The virtue of the present approach is that arbitrary “damping functions” are not required.

    Early inhibition of phospholipid synthesis in dimethyl sulfoxide (DMSO) treated friend erythroleukemia (FL) cells (1979)
    New York, NY [u.a.] : Wiley-Blackwell
    Journal of Cellular Physiology 101 (1979), S. 25-32 
    Details
    ISSN: 0021-9541

    Notes: Phosphate metabolism in Friend erythroleukemia cells undergoing DMSO-induced differentiation was studied. Thirty minutes after the cells were exposed to DMSO in medium at pH 7, an inhibition of 39% in the incorporation of phosphate into phospholipids was observed. This decrease was not due to a change in the precursor pools since phosphate uptake and the phosphorylation of the organic soluble compounds were only inhibited 13%.Inhibition of phospholipid synthesis preceded inhibition of RNA and protein synthesis and reached a maximum after 24 hours of DMSO treatment. At this time, the phospholipid content of the cells was also decreased as compared to that of the control untreated cells. Phospholipid synthesis remained at a level significantly lower than in the controls over the 4-day observation period, at which time 85% of the treated cells were benzidine positive.Separation of the different phospholipids by chromatography on thin layer silicate gel plates showed that, after one hour of DMSO treatment, more than 80% of the radioactivity was in phosphatidylcholine, phosphatidylserine and phosphatidylethanolamine. Phosphatidylethanolamine was the most inhibited. Incorporation of inositol into phospholipid was also significantly decreased. However, there was little variation in the phospholipid composition of the treated and non-treated cells other than a decrease in the percent of sphingomyelin after 48 hours of DMSO treatment.These changes in phospholipid metabolism may initiate the first step in the complex differentiation process. The phospholipids are important components of membranes and the inducers are known to influence their fluidity.
