Aerosol Particles Generated by Coughing and Sneezing of a SARS-CoV-2 (COVID-19) Host Travel over 30 m Distance by Boris Gorbunov

“…Abstract A fast-computational 3D model comprising fluid dynamics with heat transfer, mass transfer and diffusion of diluted species has been adapted and employed to evaluate dispersion of aerosol particles in various environments. Effects of convection flow, atmospheric diffusivity and humidity on evolution and travel distances of exhaled aerosol clouds by an infected person are modelled. …”

Design and Analysis of thermosyphon Solar Water Heating System. by Kakuru, Stephen

“…This research aimed at the design and analysis of a thermosyphon solar water heater that heats water using solar energy which is healthy, environmentally friendly, cost-effective, easily maintained, and simple since it depends on natural convection and gravity force for water flow. The system is made of a 4m2 flat plate collector to convert solar energy into thermal energy, an insulated stainless steel storage tank of 240 liters capacity for storing hot water, a pipe system for transporting water, and a painted mild steel frame for supporting the system. …”

A new computational framework for simulating airway resistance, fraction of exhaled nitric oxide, and diffusing capacity for nitric oxide. by Benoit Haut, Cyril Karamaoun, Clément Rigaut

“…This is implemented in the framework by solving different transport equations (momentum and convection/diffusion) describing these tests. Through numerous simulations, we demonstrate the ability of our model to reproduce results from the literature, both for healthy lungs and lungs of patients with asthma or chronic obstructive pulmonary disease. …”

Toward the calibration of 2D thermomechanical simulations of magma poor passive continental margins: method, validation and case example by Perron, Paul, Le Pourhiet, Laetitia, Jourdon, Anthony, Cornu, Tristan, Gout, Claude

“…In recent decades, geodynamic modelers have aimed to comprehend key factors governing continental rifting, such as the extension rate, lithospheric thickness, Moho mechanical coupling, and mantle convection’s thermal influence. While prior models offered insights into rifting processes, they lacked the calibration to specific Earth regions. …”

Geophysical flows over topography, a playground for laboratory experiments by Vidal, Jérémie, Noir, Jérôme, Cébron, David, Burmann, Fabian, Monville, Rémy, Giraud, Vadim, Charles, Yoann

“…More specifically, we focus on (i) the flow response to mechanical (orbital) forcings in the presence of a large-scale (ellipsoidal) topography, (ii) some effects of small-scale topography onto bulk flows and boundary-layer dynamics, and (iii) the interaction between convection and roughness. The geophysical context is briefly introduced for each case, and some experimental perspectives are drawn.…”

Effects of Precipitation on the Air Quality Index, PM2.5 Levels and on the Dry Deposition of PCDD/Fs in the Ambient Air by Ruoxin Wang, Kangping Cui, Hwey-Lin Sheu, Lin-Chi Wang, Xueyan Liu

“…However, in some cases, the increase of source emissions and atmospheric vertical convection, the effect of precipitation or air humidity increased the AQI and elevated the concentration of PM2.5, and dry deposition flux of PCDD/Fs. …”

Fingerprints of surface flows on solid substrates ablated by phase change: from laboratory experiments to planetary landscapes by Carpy, Sabrina, Berhanu, Michael, Chaigne, Martin, Courrech du Pont, Sylvain

“…In many situations, these layers are controlled by fluid flow, either natural or forced convection. In the former case, the flow may be buoyancy driven by the melting/dissolution/sublimation itself, resulting in density stratification caused by, for example, temperature/concentration gradients. …”

Design, evaluation, and future projections of the NARCliM2.0 CORDEX-CMIP6 Australasia regional climate ensemble by G. Di Virgilio, G. Di Virgilio, J. P. Evans, J. P. Evans, F. Ji, F. Ji, E. Tam, J. Kala, J. Andrys, C. Thomas, D. Choudhury, C. Rocha, S. White, Y. Li, M. El Rafei, R. Goyal, M. L. Riley, J. Lingala

“…<p>NARCliM2.0 (New South Wales and Australian Regional Climate Modelling) comprises two Weather Research and Forecasting (WRF) regional climate models (RCMs) which downscale five Coupled Model Intercomparison Project Phase 6 (CMIP6) global climate models contributing to the Coordinated Regional Downscaling Experiment (CORDEX) over Australasia at 20 km resolution and southeast Australia at 4 km convection-permitting resolution. We first describe NARCliM2.0's design, including selecting two definitive RCMs via testing 78 RCMs using different parameterisations for the planetary boundary layer, microphysics, cumulus, radiation, and land surface model (LSM). …”

Advances in the Research on Brown Carbon Aerosols: Its Concentrations, Radiative Forcing, and Effects on Climate by Shuai Li, Hua Zhang, Zhili Wang, Yonghang Chen

“…BrC heating decreases precipitation on a global scale, particularly in tropical regions with high convective and precipitation intensity, but different in some regions. (3) Uncertain optical properties of BrC, mixing ratio of radiation-absorbing aerosols in snow, snow grain size and snow coverage lead to higher uncertainties and lower confidence in the simulated distribution and radiative forcing of BrC in snow than BC. …”

Impact of stellar variability on exoplanet detectability and characterisation by Meunier, Nadège

“…Many physical processes indeed affect the radial velocity measurements: they are mostly due to magnetic features (spots and plages), flows (oscillations, granulation, supergranulation, meridional flows), and to the interactions between magnetic fields and flows (inhibition of the convective blueshift in plages). I present in more detail a selection of studies aiming at characterising the impact of stellar variability, in particular the relationship between activity indicators and radial velocities, and then focusing on mass characterisation and detection performance. …”
