井工一矿存在严重的老空区和水害。以往的单一勘探方法,如地震法、直流电法、音频大地电磁法、可控源音频大地电磁法、瞬变电磁法等,均未能探明老采空区范围和水害赋存情况。为了解决这个难题,联合采用广域电磁法和井- 地拟流场法的三位一体立体式探测技术,并利用三维反演电阻率资料精准获取富水区域和采空区的位置,确定了不同层位水的连通性,为井工一矿的安全生产提供了可靠的技术保障。结果合理、成效显著,释放了近4 km2 的可采面积。

Flow transition from laminar to turbulent mode (and vice versa)—that is, the initiation of turbulence—is one of the most important research subjects in the history of engineering. Even for pipe flow, predicting the onset of turbulence requires sophisticated instrumentation and/or direct numerical simulation, based on observing the instantaneous flow structure formation and evolution. In this work, a local Reynolds number equivalence γ (ratio of local inertia effect to viscous effect) is seen to conform to the Universal Law of the Wall, where γ = 1 represents a quantitative balance between the abovementioned two effects. This coincides with the wall layer thickness (y+ = 1, where y+ is the dimensionless distance from the wall surface defined in the Universal Law of the Wall). It is found that the characteristic of how the local derivative of γ against the local velocity changes with increasing velocity determines the onset of turbulence. For pipe flow, γ ≈ 25, and for plate flow, γ ≈ 151.5. These findings suggest that a certain combination of γ and velocity (nonlinearity) can qualify the source of turbulence (i.e., generate turbulent energy). Similarly, a re-evaluation of the previous findings reveals that only the geometrically narrow domain can act locally as the source of turbulence, with the rest of the flow field largely being left for transporting and dissipating. This understanding will have an impact on the future large-scale modeling of turbulence.
