Quadrature by Two Expansions for Evaluating Helmholtz Layer Potentials
Jared Weed, Lingyun Ding, Jingfang Huang +1
In this paper, a Quadrature by Two Expansions (QB2X) numerical integration technique is developed for the single and double layer potentials of the Helmholtz equation in two dimens…
Correlation function of a random scalar field evolving with a rapidly fluctuating Gaussian process
Jared C. Bronski, Lingyun Ding, Richard M. McLaughlin
We consider a scalar field governed by an advection-diffusion equation (or a more general evolution equation) with rapidly fluctuating, Gaussian distributed random coefficients. In…
Critical density triplets for the arrestment of a sphere falling in a sharply stratified fluid
Roberto Camassa, Lingyun Ding, Richard M. McLaughlin +3
We study the motion of a rigid sphere falling in a two-layer stratified fluid under the action of gravity in the potential flow regime. Experiments at a moderate Reynolds number of…
