So, in this paper, a circular cavity witha large radius is used to replace the straight boundary of thehalf space, then the half space problem can be changed tothe scattering problem of two circular cavities to the steadyincident P-wave . Having the aid of the mature cylinderfunction theory, the general solutions of the wave functionscan be given, and an infinite linear algebraic equations ofthe unknown coefficients in the wave functions can be gottenwith the boundary conditions and the Fourier complex seriesexpansion technology, the infinite linear algebraic equationscan be approximately solved by the finite trunction withsatisfying some definite precision, at the basis of thissolution of the equation, the variations and the lay-outs ofthe DSCF at the circular cavity boundary vs. the differentincident angles, the different embedded depths of thecircular cavity as well as the different dimensionless wavenumber of the incident P-wave.

Experiment shows that both the dry plate pressure drop and the wet plate pressure drop increase with the increase of the kinetic energy factor in plate hole but have no influence of the height of cap. The wet plate pressure drop linearly ascends as the clear liquid height increases. Liquid lift-up increases at first then decreases with the increasing of the kinetic energy factor in plate hole, increases with the clear liquid height increasing and the height of cap decreasing, but as the kinetic energy factor in plate hole increased, the influence of height of cap will gradually decreased.
实验表明干板压降、湿板压降均随板孔动能因子的增大而增大,不受罩体高度变化的影响,湿板压降随清液层高度的增大而增大,成正比关系;液体提升量随板孔动能因子的增大先增大后减小,随清液层高度的增大而增大,随罩体高度的增大而减小,但随板孔动能因子的增加,罩体高度的影响逐渐变小;漏液量随板孔动能因子的增大迅速减小,随清液层高度的增大而增大,但接近漏液点时清液层高度的影响不明显。
