M o

Definition

quotient of gravitational forces and viscous forces for gas bubbles in a liquid, or liquid drops in a gas, expressed by

$M o = \frac{g η^{4}}{ρ γ^{3}} (\frac{ρ_{b}}{ρ} - 1)$ ; where

$g$ :: is acceleration of free fall (ISO 80000-3: Space and time),

$η$ :: is dynamic viscosity (ISO 80000-4: Mechanics) of the surrounding fluid,

$ρ$ :: is mass density (ISO 80000-4: Mechanics) of the surrounding fluid,

$γ$ :: is surface tension (ISO 80000-4: Mechanics) of the interface, and

$ρ_{b}$ :: is mass density (ISO 80000-4: Mechanics) of the bubble or drop

quotient des forces de gravitation par les forces visqueuses pour des bulles de gaz dans un liquide ou des gouttes de liquide dans un gaz, exprimé par:

$M o = \frac{g η^{4}}{ρ γ^{3}} (\frac{ρ_{b}}{ρ} - 1)$ ; où

$g$ :: est l'accélération due à la pesanteur (ISO 80000-3: Space and time);

$η$ :: est la viscosité dynamique (ISO 80000-4: Mechanics) du fluide environnant;

$ρ$ :: est la masse volumique (ISO 80000-4: Mechanics) du fluide environnant;

$γ$ :: est la tension superficielle (ISO 80000-4: Mechanics) de l'interface; et

$ρ_{b}$ :: est la masse volumique (ISO 80000-4: Mechanics) de la bulle ou de la goutte

Notes

The Morton number is used to determine the shape of bubbles or drops.

The Morton number is also given by

$M o = W e^{3} F r^{- 2} R e^{- 4}$ ; where

$W e$ :: is the Weber number (Weber number),

$F r$ :: is the Froude number (Froude number), and

$R e$ :: is the Reynolds number (Reynolds number).

Le nombre de Morton est utilisé pour déterminer la forme des bulles ou des gouttes.

Le nombre de Morton est également donné par:

$M o = W e^{3} F r^{- 2} R e^{- 4}$ ; où

$W e$ :: est le nombre de Weber (Weber number);

$F r$ :: est le nombre de Froude (Froude number); et

$R e$ :: est le nombre de Reynolds (Reynolds number).
