On the heat transfer to an accelerated translating droplet [PDF]
Theoretical and Applied Mechanics, 2004 An analysis is made for the transient response behavior of the both, outer and inner, thermal boundary layers of a fluid sphere moving at constant acceleration with internal circulation in an other viscous fluid of large extent initially at rest under the condition of large Reynolds and Peclet numbers.

Heat transfer within combusting droplets [PDF]
Proceedings of the Combustion Institute, 2007 The improvement of the basic understanding of heat transfer in sprays is a key point in many engineering applications. In this paper, the temperature field within combusting ethanol droplets in linear stream is investigated by the two-color laser induced fluorescence technique. Additionally, a heat transfer model within the droplet is developed, taking

Dynamics of Evaporating Respiratory Droplets in the Vicinity of Vortex Dipoles [PDF]
Orr Avni, Yuval Dagan, Dynamics of evaporating respiratory
droplets in the vicinity of vortex dipoles, International Journal of
Multiphase Flow, Volume 148, 2022, 103901, ISSN 0301-9322,, 2021 A new mathematical analysis of exhaled respiratory droplet dynamics and settling distances in the vicinity of vortical environments is presented. Recent experimental and theoretical studies suggest that vortical flow structures may enhance the settling distances of exhaled respiratory droplets beyond the two-meter distancing rule recommended by health ...
