Numerical simulation of electro-conjugate fluid flow considering electric double layer

Mechanical Engineering Journal, 2015
An electro-conjugate fluid (ECF) is a dielectric liquid generating powerful flow when high DC voltage is applied with electrodes inserted. The ECF flow is generally known as a kind of electrohydrodynamics phenomenon.

On the multi-frequency inverse source problem in heterogeneous media

, 2012
The inverse source problem where an unknown source is to be identified from the knowledge of its radiated wave is studied. The focus is placed on the effect that multi-frequency data has on establishing uniqueness.

Exact nonclassical symmetry solutions of Arrhenius reaction-diffusion

, 2015
Exact solutions for nonlinear Arrhenius reaction-diffusion are constructed in $n$ dimensions. A single relationship between nonlinear diffusivity and the nonlinear reaction term leads to a nonclassical Lie symmetry whose invariant solutions have a heat ...

Fast integral equation methods for the heat equation and the modified Helmholtz equation in two dimensions

, 2010
We present an efficient integral equation approach to solve the heat equation, $u_t (\x) - u(\x) = F(\x,t)$, in a two-dimensional, multiply connected domain, and with Dirichlet boundary conditions. Instead of using integral equations based on the heat kernel, we take the approach of discretizing in time, first.

Streaming Potential Coupling Coefficient and Transport Properties of Unsaturated Carbonate Rocks

Vadose Zone Journal, 2018
We measured the streaming potential coupling coefficient of natural saturated and unsaturated carbonate rocks. Saturation was achieved with NaCl brines with salinities ranging from 2 × 10 to 2.0 mol L.
