WebApr 12, 2024 · When the blast height is low (less than or equal to the ignition radius), the time of shock wave propagation to the ground is less than the time of shock wave propagation to the symmetry axis, and the overpressure curves have two peaks (as the curves of H ≤ 2 m are shown in Fig. 18). The closer is to the ground, the farther the … WebMay 13, 2024 · At present, researchers generally use the method of scaling law to analyze the beam quality of laser far-field long exposure facula; that is, through a 4D wave optics program to simulate the far-field peak intensity and the beam expansion radius under a certain ring energy under different turbulence, thermal blooming, initial beam quality, and ...
WebThis study investigates the use of a recently published generalized scaling law [J. Opt. Soc. Am. A 33(12), 2477-2484 (2016)]. In practice, the generalized scaling law accurately predicts the diffraction-limited peak irradiance in the far-field given the beam power, wavelength, propagation distance, field-effective area, and field-out-coupling factor. WebA general far-field wave propagation scaling law is developed. The formulation is simple but predicts diffraction peak irradiance accurately in the far field, regardless of the near-field beam ...
WebThe wave equation u tt = c2∇2 is simply Newton’s second law (F = ma) and Hooke’s law (F = k∆x) combined, so that acceleration u tt is proportional to the relative displacement of u(x,y,z) compared to its neighbours. The constant c2 comes from mass density and elasticity, as expected in Newton’s and Hooke’s laws. 1.2 Deriving the 1D ...
