On this basis, a numerical analysis method is used to discuss the temperature field change law of the surrounding rock and the thermal insulation measures of the Galongla tunnel in Tibet under the condition of ventilation.
It is suggested that a more realistic description of fire scenarios is still needed for a performance-based structural fire design, based on a better consideration of ventilation conditions and thermal properties of boundary enclosure.
In addition, crowded living conditions, lack of ventilation in temporary housing, malnutrition, and lack of education facilitated the spread of TB [ 9].
Therefore, better conditions of natural ventilation were obtained with a thin and horizontal positioning of the elements.
Animals were housed in plastic cages and maintained in conditions of good ventilation, normal temperatures, and humidity ranges (55 ± 5%), a 12-h light-dark cycle.
Nevertheless, under conditions of normoxia, ventilation V̇E is matched to V̇o2 such that the convection requirement V̇EV̇o2 is similar to that reported for other mammals (approx. 37).
Animals were housed collectively in plastic cages, maintained under standard conditions of light, ventilation, temperature, and humidity, and allowed free access to the standard pellet diet and tap water.
It is clearly demonstrated that, for the experimental conditions of the ventilation experiment (VE) that abstracted physical and empirical models of the tunnel, can be used successfully to represent the hydraulic behaviour of the tunnel and the hydraulic interaction between the tunnel and the surrounding rock mass.
However, during the dynamic conditions of mechanical ventilation the hysteresis area is biased by resistive pressure portions.
