New Lagrangian view of vorticity evolution in two-dimensional flows of liquid and gas [PDF]

open access: yesИзвестия высших учебных заведений: Прикладная нелинейная динамика, 2022
Purpose of the study is to obtain formulas for such a speed of imaginary particles that the circulation of the speed of a (real) fluid along any circuit consisting of these imaginary particles changes (in the process of motion of imaginary particles ...

Reconciling opposite trends in the observed and simulated equatorial Pacific zonal sea surface temperature gradient

open access: yesGeoscience Letters, 2023
The reasons for large discrepancies between observations and simulations, as well as for uncertainties in projections of the equatorial Pacific zonal sea surface temperature (SST) gradient, are controversial.

Subseasonal Prediction of Regional Antarctic Sea Ice by a Deep Learning Model

open access: yesGeophysical Research Letters, 2023
Antarctic sea ice concentration (SIC) prediction at seasonal scale has been documented, but a gap remains at subseasonal scale (1–8 weeks) due to limited understanding of ice‐related physical mechanisms.

Quantifying 4D flow cardiovascular magnetic resonance vortices in patients with pulmonary hypertension: A pilot study

open access: yesPulmonary Circulation, 2023
In this 4D flow cardiovascular magnetic resonance (CMR) study, vortical blood flow in the main pulmonary artery (MPA) is quantified using circulation (ᴦ), a metric used in fluid dynamics to quantify the rotational components of flow. Circulation (ᴦ) is a

Impact of vertical coordinate systems on simulations of barotropic and baroclinic tides in the Yellow Sea using a regional MOM6 configuration for the Northwest Pacific [PDF]

open access: yesGeoscientific Model Development
An accurate representation of tidal dynamics is critical for simulating physical and biogeochemical processes in marginal seas, such as the Yellow Sea, where energetic tides and strong seasonal stratification coexist.

Simulating Fracture Sealing by Granular LCM Particles in Geothermal Drilling

open access: yesEnergies, 2020
Lost circulation occurs when the returned fluid is less than what is pumped into the well due to loss of fluid to pores or fractures. A lost-circulation event is a common occurrence in a geothermal well.
