Source Published financial statements, as at October. Best stock market brokers in dubai. Research that investigates bioaerosol emissions from animal transport vehicles (ATVs) and their importance in the spread of harmful airborne agents while the ATVs travel on roads is limited.To investigate the dynamical behaviour of theoretically released particles from a moving ATV, the open-source computational fluid dynamics (CFD) software Open FOAM was used to calculate the external and internal air flow fields with passive and forced ventilated openings of a common ATV moving at a speed of 80 km/h.In addition to a computed flow rate of approximately 40,000 m/h crossing the interior of the ATV, the visualization of the trajectories has demonstrated distinct patterns of the spatial distribution of potentially released bioaerosols in the vicinity of the ATV.Although the front openings show the highest air flow to the outside, the recirculations of air masses between the interior of the ATV and the atmosphere also occur, which complicate the emission and the dispersion characterizations.

To specify the future emission rates of ATVs, a database of bioaerosol concentrations within the ATV is necessary in conjunction with high-performance computing resources to simulate the potential dispersion of bioaerosols in the environment.Natural ventilation is the most common passive cooling system in livestock buildings.The aim of this research is to assess airflow distribution inside a free-stall barn for dairy cows by computational fluid dynamics (CFD) modelling and simulation. The model is validated by using the average values of experimental data acquired in a free-stall barn, which is considered relevant because it is located in a region characterised by hot climate conditions during the summer that could induce animal heat stress.Simulations are carried out in steady-state conditions, and simulated data are validated by the average values of air velocity measurements.Since the modelled air velocity distribution in the barn fits the real one well, the CFD model is considered reliable to simulate other conditions.

Nowadays, only few research studies regarded the analysis of natural ventilation through large openings, which often characterize semi-open buildings for dairy cows in hot climate regions because they can ensure an air change adequate to guarantee the animal’s well-being [1].This kind of research is still challenging in the field of CFD applications because of bidirectional flows through large openings.In this paper, by developing a CFD-based methodology, wind-driven natural ventilation (i.e., an internal ventilation induced by the external wind entering from the openings) was studied in a semi-open free-stall barn for dairy cows, located in southern Italy, in a region highly characterised by hot climate conditions during summer that could induce animal heat stress.
