The shape of a shock wave front diffracting on a perforated wall is determined by comparing numerical data and experimental findings. Experiments were conducted in a 60mm脳150mm cross sectional area shock tube equipped with a double-exposure holographic interferometer. The numerical simulation was ...

Thorpe,S. A.摘要: This paper discusses the effect of the shape of internal wave groups on their "duration" or "lifetime"—how long they retain their form before their component waves disperse. The methodology devised by Smith and Brulefert (2010) to study the dispersion of surface wave ...

Oscillating shape motion of a freely falling and bouncing water droplet has long fascinated and inspired scientists. We propose dynamic non-linear equations for closed, two-dimensional surfaces in gravity and apply it to analyze shape dynamics of freely falling and bouncing drops. The analytic and ...
This paper deals with the influence of piecewise smooth boundary conditions on the distribution of the eigenvalues of the negative Laplacian in 3 . The asymptotic expansion of the trace of the wave operator μ ^(t)=∑ v=1 ∞ exp(-itμ v 1/2 ) for small |t|, where {μ v } v=1 ...
The wave propagation in a long pyroelectric cylinder of crystal class 6 with inner and outer irregular shape is considered. The frequency equation has been derived for the traction free, earth connected, and thermally insulated surfaces. The boundary conditions at the arbitrarily shaped boundaries are...
