Dm. Christopher et Bx. Wang, Similarity simulation for Marangoni convection around vapor bubble during nucleation and growth, INT J HEAT, 44(4), 2001, pp. 799-810
Marangoni convection occurs around vapor bubbles during nucleation and grow
th due to the temperature variation along the surface. The surface tension
variation resulting from the temperature gradient along the surface causes
Marangoni convection. Marangoni convection is of importance in crystal grow
th melts and may influence other processes with liquid-vapor interfaces, in
addition to boiling. The influence of Marangoni induced convection is more
obvious under microgravity but also occurs in earth gravity. This paper pr
esents a similarity solution for Marangoni induced flow both for the veloci
ty profile and the temperature profile, assuming developing boundary-layer
flow along a surface with various imposed temperature profiles. The surface
velocity, the total flow rate and the heat transfer characteristics are gi
ven for various temperature profiles and various Prandtl numbers. Since the
predicted boundary layer thickness would be much less than the diameter of
vapor bubbles during nucleate boiling, the bubble surface curvature effect
s can be neglected and this analysis can be used as a first estimate of the
effect of Marangoni flow around a vapor bubble. (C) 2001 Elsevier Science
