Conjugate heat transfer effects on flow boiling in microchannels
F. Municchi, I. El Mellas, O. K. Matar +1
This article presents a computational study of saturated flow boiling in non-circular microchannels. The unit channel of a multi-microchannel evaporator, consisting of the fluidic…
On the missing link between pressure drop, viscous dissipation and the turbulent energy spectrum
Arnoldo Badillo, Omar Matar
We present convincing evidence of a direct connection between the pressure drop, viscous dissipation, and the turbulent energy spectrum. We use this finding to explain Nikuradse's…
Role of surfactant-induced Marangoni stresses in drop-interface coalescence
C. R. Constante-Amores, A. Batchvarov, L. Kahouadji +4
We study the effect of surfactants on the dynamics of a drop-interface coalescence using full three-dimensional direct numerical simulations. We employ a hybrid interface-tracking/…
Direct numerical simulations of transient turbulent jets: vortex-interface interactions
Cristian R. Constante-Amores, Lyes Kahouadji, Assen Batchvarov +4
The breakup of an interface into a cascade of droplets and their subsequent coalescence is a generic problem of central importance to a large number of industrial settings such as…
Spreading and retraction dynamics of sessileevaporating droplets comprising volatile binary mixtures
A. G. L. Williams. G. Karapetsas, D. Mamalis, K. Sefiane +2
The dynamics of thin volatile droplets comprising of binary mixtures deposited on a heated substrate are investigated. Using lubrication theory, we develop a novel one-sided model…
Rico and the jets: Direct numerical simulations of turbulent liquid jets
C. R. Constante-Amores, L. Kahouadji, A. Batchvarov +4
This paper is associated with a poster winner of a 2019 American Physical Society Division of Fluid Dynamics (DFD) Milton van Dyke Award for work presented at the DFD Gallery of Fl…
