Drag coefficient and relative velocity in bubbly, droplet or particulate flows

Ishii, Mamoru, Zuber, Novak·1979·AIChE Journal

Abstract

Abstract Drag coefficient and relative motion correlations for dispersed two‐phase flows of bubbles, drops, and particles were developed from simple similarity criteria and a mixture viscosity model. The results are compared with a number of experimental data, and satisfactory agreements are obtained at wide ranges of the particle concentration and Reynolds number. Characteristics differences between fluid particle systems and solid particle systems at higher Reynolds numbers or at higher concentration regimes were successfully predicted by the model. Results showed that the drag law in various dispersed two‐phase flows could be put on a general and unified base by the present method.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Ishii and Zuber [258] considered the dense particle effect in the computation of the drag coefficient utilizing a mixture viscosity, and the drag coefficient assumes different forms depending on the flow regimes (viscous, distorted particle, churn turbulent).

    “Ishii and Zuber [258] considered the dense particle effect in the computation of the drag coefficient utilizing of a mixture viscosity. The drag coefficient assumes different forms depending on the flow regimes, i.e., the viscous CD ( sphere ) , the distorted particle CD ( ellipse ) , and the churn turbulent flow regime CD ( cap ) .”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
