Physics of Fluids, 2014 We investigate the non-linear equilibration of a two-layer quasi-geostrophic flow in a channel with an initial eastward baroclinically unstable jet in the upper layer, paying particular attention to the role of bottom friction. In the limit of low bottom friction, classical theory of geostrophic turbulence predicts an inverse cascade of kinetic energy ...

LightCUD: a program for diagnosing IBD based on human gut microbiome data
BioData Mining, 2021 Background The diagnosis of inflammatory bowel disease (IBD) and discrimination between the types of IBD are clinically important. IBD is associated with marked changes in the intestinal microbiota. Advances in next-generation sequencing (NGS) technology

Inverse design of mesoscopic models for compressible flow using the Chapman-Enskog analysis
Advances in Aerodynamics, 2021 In this paper, based on simplified Boltzmann equation, we explore the inverse-design of mesoscopic models for compressible flow using the Chapman-Enskog analysis. Starting from the single-relaxation-time Boltzmann equation with an additional source term,

Unified energy law for fluctuating density wave orders in cuprate pseudogap phase
Communications Physics, 2022 The origin of the pseudogap in the cuprates and how it is related to the mechanism of their superconductivity has been a topic of long standing debate. Here, the authors suggest that the pseudogap is governed by a unified energy law the basis for which ...

Computers and turbulence [PDF]
European Journal of Mechanics - B/Fluids, 2020 This paper briefly reviews the influence that the rapid evolution of computer power in the last decades has had on turbulence research. It is argued that it can be divided into three stages. In the earliest (`heroic') one, simulations were expensive and could at most be considered as substitutes for experiments. Later, as computers grew faster and some

Criteria of tracking vortex surfaces in turbulent-like flows
Advances in Aerodynamics, 2022 We propose criteria of tracking vortex surfaces in complex flows based on the vortex-surface field (VSF). The criteria characterize the accuracy and Lagrangian tracking performance of the numerical VSF solution, and determine the time period when the ...

Fluids, 2023 This paper addresses one of the major obstacles arising in the high-fidelity scale-resolving simulations of turbulent flows inside ducts with the walls covered by acoustic liners in order to attenuate the sound radiated from the duct.

Statistical Properties of Turbulence: An Overview [PDF]
, 2009 We present an introductory overview of several challenging problems in the statistical characterisation of turbulence. We provide examples from fluid turbulence in three and two dimensions, from the turbulent advection of passive scalars, turbulence in ...
