Analytical and numerical study of nonlinear Riesz-Caputo boundary value problems
Chiara Sorgentone, Enza Pellegrino, Francesca Pitolli
Fractional boundary value problems are often used to model complex systems and processes characterized by memory effects and anomalous diffusion. In this paper, we consider nonline…
Estimation of quadrature errors for layer potentials evaluated near surfaces with spherical topology
Chiara Sorgentone, Anna-Karin Tornberg
Numerical simulations with rigid particles, drops or vesicles constitute some examples that involve 3D objects with spherical topology. When the numerical method is based on bounda…
Tandem droplet locomotion in a uniform electric field
Chiara Sorgentone, Petia M. Vlahovska
An isolated charge-neutral droplet in a uniform electric field experiences no net force. However, a droplet pair can move in response to field-induced dipolar and hydrodynamic inte…
Note on the pairwise interactions of surfactant-covered drops in a uniform electric field
Chiara Sorgentone, Petia Vlahovska
We study the effect of surfactant on the pairwise interactions of drops in an applied uniform DC electric field using a combination of numerical simulations based on a boundary int…
Quadrature error estimates for layer potentials evaluated near curved surfaces in three dimensions
Ludvig af Klinteberg, Chiara Sorgentone, Anna-Karin Tornberg
The quadrature error associated with a regular quadrature rule for evaluation of a layer potential increases rapidly when the evaluation point approaches the surface and the integr…
Numerical and asymptotic analysis of the three-dimensional electrohydrodynamic interactions of drop pairs
Chiara Sorgentone, Jeremy I. Kach, Aditya S. Khair +2
We study the pairwise interactions of drops in an applied uniform DC electric field within the framework of the leaky dielectric model. We develop three-dimensional numerical simul…
A 3D boundary integral method for the electrohydrodynamics of surfactant-covered drops
Chiara Sorgentone, Anna-Karin Tornberg, Petia Vlahovska
We present a highly accurate numerical method based on a boundary integral formulation and the leaky dielectric model to study the dynamics of surfactant-covered drops in the prese…
A highly accurate boundary integral equation method for surfactant-laden drops in 3D
Chiara Sorgentone, Anna-Karin Tornberg
The presence of surfactants alters the dynamics of viscous drops immersed in an ambient viscous fluid. This is specifically true at small scales, such as in applications of droplet…
