Modeling Surface Wave Propagation over Meniscus and Scattering by a Surface-piercing Barrier

Guoqin Liu, Zhengwu Wang, Likun Zhang

Recent experiments have revealed that the meniscus formed near a surface-piercing barrier can significantly alter the propagation and scattering of capillary-gravity surface waves,…

Scattering of Capillary-Gravity Waves by a Fixed, Semi-immersed Cylindrical Barrier with Contact Line Dissipation

Guoqin Liu, Likun Zhang

The scattering of surface waves by structures intersecting liquid surfaces is fundamental in fluid mechanics, with prior studies exploring gravity, capillary, and capillary-gravity…

Meniscus-Driven Modulation of Surface Wave Transmission Across Barriers

Zhengwu Wang, Guoqin Liu, Likun Zhang

Meniscus oscillations at interfaces between liquids, solids, and air significantly impact fluid dynamics and control. While idealized models exist, experimental data on capillary-g…

Directional radiation of sound waves by a subwavelength source

Xu-Dong Fan, Yi-Fan Zhu, Bin Liang +2

We propose and experimentally achieve a directional dipole field radiated by an omnidirectional monopole source enclosed in a subwavelength structure of acoustically hybrid resonan…

Oscillation-free method for semilinear diffusion equations under noisy initial conditions

R. C. Harwood, Likun Zhang, V. S. Manoranjan

Noise in initial conditions from measurement errors can create unwanted oscillations which propagate in numerical solutions. We present a technique of prohibiting such oscillation…
