A simulation method was developed to obtain the flow field load distribution in the coal mine lane and pressure load of each part for the refuge chamber. Firstly,a physical model of a full-size explosiontest lane was established,which included the refuge chamber. With the calculations of the ...
Secondly, the CFD software FLACS is assessed against the experimental data. The characteristic phenomena of vented explosion are observed for hydrogen-air mixtures ignited at different ignition positions, such as Helmholtz oscillation for front ignition, the interaction between external explosion and ...
The technology of the weak explosion wave sootblowing is dirt-removing method of the end of the boiler is heated in the surface to develop in recent years,It is a New type patented product with non-maintaining and energy-efficient,it can run steadily and reliably for a long term. 弱爆炸...
These sizes of instabilities cannot be resolved in CFD simula- tions if the characteristic size ofthe problem is signif- icantly larger than the real flame-front thickness, such as in the case ofgaseous Large eddy simulation is an approach to numerical simulations of turbulent re deflagrationlarge...
Specifically, we seek the rate of flame propagation through a mixture of sodium azide (NaN3) and hematitederived iron oxide (Fe2O3) for practically interesting stoichiometries, for which the oxide is present in excess in the pristine pyrotechnic. For a uniform grain, the hotboundary products ...
The extended finite element method is a method of discontinuous interface processing, and special crack tracking techniques, such as Level Sets [9] and Fast Marching [10], are used to track crack surfaces. Li et al. [11,12] consider the effects of natural fracture on fracture propagation. ...
