Formula

Ma = |dσ/dT| ΔT L / (μ α) veya Ma = |dσ/dT| |dT/dz| L² / (μ α)

Source / method note

The Marangoni number is a fundamental dimensionless parameter in thermocapillary convection, microfluidics, and microgravity heat transfer. The magnitude of |dσ/dT| determines the dimensionless intensity.
