Marangoni number
Input(s)
SG: Change in Surface Tension per unit Temp (N/m/K)
L: Characteristic length (m)
\(\mathrm{dT}\): Speed of sound in the medium \((\mathrm{K})\)
\(\alpha\): Thermal diffusivity \(\left(\mathrm{m}^{2} / \mathrm{s}\right)\)
\(\sigma\): Dynamic viscosity \((\mathrm{kg} /(\mathrm{s} \mathrm{m}))\)
Output(s)
\(\mathrm{Mg}\): Marangoni number (dimensionless)
Formula(s)
\[
M g=S G * L * \frac{d T}{\alpha * \sigma}
\]
