(physics)
A dimensionless number used in the study of convection currents, equal to the product of a fluid's dynamic viscosity and its thermal diffusivity, divided by the product of its undisturbed surface tension and a layer thickness.

[5] concluded that the surface deformation had a negligible influence on the qualitative aspects of the flow field structure at low crispation number. Cicek and Baytas [6] studied numerically the combined effects of natural and Marangoni convection in square cavity with three different cases of boundary conditions.
