DOI: 10.1016/j.expthermflusci.2017.12.019
Abstract: Abstract This work characterizes the local dissipation length-scale η and its related quantities in turbulent (round and square) jets. It is revealed that the probability density function (PDF) of η , denoted by Q (… read more here.

DOI: 10.1016/j.physd.2021.133066
Abstract: Abstract. We derive dyadic models for the magnetohydrodynamics with Hall effect by including the intermittency dimension as a parameter. For such dyadic models, existence of global weak solutions is established. In addition, local strong solution… read more here.

DOI: 10.1016/j.powtec.2016.12.060
Abstract: In the riser of a gas-solid circulating fluidised bed (CFB) with Geldart A particles, the multiscale interactions and diverse coherent structures give rise to an important hydrodynamic phenomenon called flow intermittency. In this work, the… read more here.

DOI: 10.1016/j.wavemoti.2018.10.003
Abstract: Abstract The dynamic and thermal regimes of the climate are regulated by an exchange of energy and momentum between the atmosphere and the ocean. The role exerted by surface waves on this interchange is particularly… read more here.

DOI: 10.1017/jfm.2017.48
Abstract: Stratified shear flows occur in many geophysical contexts, from oceanic overflows and river estuaries to wind-driven thermocline layers. We explore a turbulent wall-bounded shear flow of lighter miscible fluid into a quiescent fluid of higher… read more here.

DOI: 10.1017/jfm.2021.33
Abstract: Abstract The interaction of fluids with surface-mounted obstacles in canopy flows leads to strong turbulence that dominates dispersion and mixing in the neutrally stable atmospheric surface layer. This work focuses on intermittency in the Lagrangian… read more here.

How Fast or How Many? Sources of Intermittent Sediment Transport
Sign Up to like & getrecommendations! Published in 2023 at "Geophysical Research Letters"
DOI: 10.1029/2022gl101919
Abstract: Near the threshold of grain motion, sediment transport is “on‐off” intermittent, characterized by large but rare bursts separated by long periods of low transport. Without models that can account for the effects of intermittency, measurements… read more here.

DOI: 10.1038/s41598-020-80331-z
Abstract: Seasonal surface chlorophyll (SChl) blooms are very chaotic in nature, but traditional bloom paradigms have climbed out of these subseasonal variations. Here we highlight the leading order role of wind bursts, by conjoining two decades… read more here.
