Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
This paper aims at investigating, both through a theoretical and an experimental analysis, the discharging phase of a blowing unit of compressed air, used for the industrial production of plastic made bottles. The proposed mathematical model leads to a system of differential equations describing the flow through an open system. The solution was found by numerical simulations using the software Matlab, determining the gas density, pressure, temperature and mass flow rate, as functions of time. The pressure loss across the down flow has been tackled with a theoretical investigation, determining the mechanical loss coefficient β and evaluating the effect of these losses on the emptying time of the blowing unit. The numerical results agree with the real discharging times obtained by experimental tests, and the proposed improvements allow to reduce loss of pressure and the emptying time of 35% and 20% respectively. © Antinori and Spiga; Licensee Bentham Open.
