average wind pressure coefficient and the fluctuating wind pressure coefficient of the gas tank, comparing them with results from wind tunnel tests. The comparison of average wind pressure coefficients between field measurements and wind tunnel tests is shown in Fig.3. It can be seen that the fiel...
The prospects for research on the design theory and safety assurance of large oil and gas storage tanks are presented through various methods, including field measurements of near-surface wind fields and wind effects, wind tunnel tests utilizing aeroelastic models, numerical ...
The rock mass around deep roadways has obvious creep characteristics in high-stress environments. Meanwhile, the cyclic impact load induced by roof fracturing also causes dynamic damage to the surrounding rock, leading to long-term large deformation. Thi
This study conducted a large-scale test on underground tunnel excited by two close-in subsurface explosions. The horizontal and vertical acceleration were recorded on the vertical wall of the tunnel and the free field data including the acceleration on the ground surface at 11-meter distance from ...

In this instance, the CRR under consideration is the twin-rotor fan that provides the flow to the wind tunnel. In order to measure the tonal and broadband noise resulting from the viscous wake interactions, an array of wall-mounted microphones has been designed, to be located in the ...
They studied the formation, propagation, and interaction of the shock wave of the composite charge for different initiation modes. Zhang et al. [22] developed an efficient numerical simulation method to predict blast loads arising from large TNT equivalent explosives, to estimate the consequences of...
I’m never going to be up for a 5k run, but when the weather is mild-cold, I have so much more energy and mental focus and so much less pain. It has become important for me to keep notes when I am in different climates because it’s easy to forget how dramatically the heat ...
