On the mathematical fluid dynamics of the atmospheric Walker circulation
Monatshefte Fur Mathematik, 2022 AbstractStarting from the general, governing equations for a viscous, compressible fluid, with an associated description of its thermodynamics, we outline an asymptotic derivation based on the thin-shell approximation. [The details appear in another publication.] This produces a reduced system of equations which retain all the dynamics and ...

Computational Fluid Dynamics for Brain Circulation and Aneurysm with Therapeutic Devices [PDF]
Interventional Neuroradiology, 2004 We analysed fluid dynamics at brain arteries having multiple inflow and out flow like Willis ring based on clinical imaging modalities. In addition, we analysed fluid dynamics with therapeutic devices like coils and stents to simulate their influences to blood flow.

Fluid simulation in a cyclone reverse circulation well washing device based on computational fluid dynamics [PDF]
Energy Science & Engineering, 2019 This paper instructs the working principle of the well washing device and its parameter optimization in practical applications. A fluent fluid engineering simulation software was used to establish the calculation model of the bottom flow field. The fluid

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

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

Indo-Pacific warm pool present warming attribution and future projection constraint
Environmental Research Letters, 2022 The Indo-Pacific warm pool (IPWP) has warmed and expanded substantially over the past decades, which has significantly affected the hydrological cycle and global climate system.

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]
Geoscientific Model DevelopmentAn 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
Energies, 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.
