This makes it possible to compare the evolution of the droplet impact on various surface structures. The impact behaviors of retraction–oscillation and …
Propagating wave spherical spreading (or geometric spreading) …
WebFor a wave propagating spherically from a point source, the radius of curvature is equal to the radius ( r) of the sphere that the wavefront constitutes at the time of investigation. … WebSpherical divergence correction This correction compensates for loss of amplitudes due to spherical wavefront spreading. If 1/dist for Basis for spherical spreading, the gain correction is If 1/(time*vel**2) for Basis for spherical spreading, the gain correction is t is time and v(t) is an RMS (stacking) velocity function.

Web3. sep 2024 · As the Weber number increases and the contact angle decreases, the effect of the diameter ratio on the maximum spreading becomes more conspicuous. Based on the energy conservation, a theoretical model considering the gravity effect is developed to describe the maximum spreading factor of an impacting droplet on a spherical surface. WebY ℓ m are the spherical harmonics and; the superscript * denotes complex conjugation. Note that the complex conjugation can be interchanged between the two spherical harmonics due to symmetry.
