Sentence examples for ventilation speed from inspiring English sources

According to the assessment results, proper ventilation speed, safe mixture ratio and location of gas-detecting devices have been proposed to guarantee the security in case of leakage.

To achieve the previous purposes, a stationary database that depends on HRR, its location, and the ventilation speed is calculated with CFD programs; the data are compared with temperatures measured by the sensors located inside the tunnel.

Specifically, we investigate the influence of ventilation speed magnitude, vmax, the equivalent diameter of particles of the porous medium, dp, the porosity of the porous medium, ϕ, the initial temperature in the free-flow region, Tff, and the initial temperature in the porous-medium region, Tpm, on the characteristic drying curves of a thin ceramic layer.

This study revealed the combined effects of vehicle motion, buoyancy/gravity force, and low ventilation speed.

As a result, the high DPM plume that hung on the roof upstream of the loading point was diluted by the higher ventilation speed as the truck drove by as shown in Figs. 10 and 11.

(1) When the ventilation speed is less than 3 m/s, the miners in lane 1 should evacuate to the upstream side of the fire scene, and the miners in lane 2 could select either the air intake end or the air door as the evacuation destination.

The spreading rules and characteristics of concentration field and temperature field of smoke flow with different longitudinal ventilation speeds were studied, which may provide the theoretical background for evacuation design in tunnel fire.

The results show that ASET changes with the ventilation speeds.

(3) Two evacuation patterns affected by the ventilation speeds are advanced.

To investigate the influence of air flow on fire smoke development, the ventilation speeds are set as 0.3, 1.5, 3.0, and 4.0 m/s.

The descending order of the ASET values under various ventilation speeds can be sorted as follows: 4, 0.3, and 3 m/s.
