TL;DR: In this article, an integrated risk assessment is presented for SARS-CoV-2 close proximity exposure between a speaking infectious subject and a susceptible subject, based on a three-dimensional transient numerical model for the description of exhaled droplet spread once emitted by a speaking person, coupled with a recently proposed SARS CoV2 emission approach.

TL;DR: An experimental campaign was performed to evaluate the exposure to second-hand aerosol from conventional and electronic cigarettes and to estimate the consequent dose received by passive smokers/vapers and the related lung cancer risk.

TL;DR: In this article, the authors numerically investigate dynamic heat transfer related to free convection in porous and partially porous cavities, paying particular attention to the dependence of velocity and temperature fields on Rayleigh (Ra) number, porous layer permeability, and cavity aspect ratio (AR), the ratio between its height and width.

TL;DR: A Reynolds Averaged Navier-Stokes-based CFD model is used in order to investigate the performance of an innovative, real scale double-bladed wind turbine, and the real scale wind turbine performance is analysed by numerically evaluating the power and torque coefficients.

TL;DR: In this article, the authors used the SA turbulence model for the first time for the simulation of turbulent flow in a street canyon, which was able to accurately reproduce the turbulent characteristics of the flow compared with results from real street canyon experiments, wind tunnel experiments, and also to that obtained with RANS simulations.
