Marangoni and Stability Studies on Fiber-Supported Methanol Droplets Evaporating in Reduced Gravity
Harry A. Dwyer,Benjamin D. Shaw +1 more
TL;DR: In this paper, a numerical study of the Marangoni forces on a methanol droplet supported by a fiber has been carried out for an evaporating methanoline droplet in both dry air and humid air environments, with the focus being the development of instabilities that form early in the lifetime of a droplet.

Theoretical analysis of Marangoni instability of an evaporating droplet by energy method
Vai-Meng Ha,Chun-Liang Lai +1 more
TL;DR: In this article, the energy method was applied to investigate the stability of an evaporating droplet against disturbances of any amplitude, and the results predicted by the present study possess similar trends with those acquired by the linear stability analysis, indicating that both the increase of surface temperature reduction and the growth of the thermal boundary layer near the free surface are conducive to the onset of instability.
