A common approach to fluid flow modelling is based on a fine spatial discretization of the Navier-Stokes equations, which results in a large number of flow variables (i.e., microstates). For the purpose of flow control, the flow variables may be considered to be aggregated on a macroscopic level that goes beyond the fine modelling grid for a practical application. This paper addresses the problem...
We present a model for the operation of a single-island adiabatic electron pump with field-effect transistors acting as tunable barriers. We account for the electrostatics by modeling the capacitive network and fit the parameters of the gate-dependent barrier conductances which include exponential dependence in the subthreshold regime. This procedure results in the knowledge of the parametric dependence...
In this paper, we introduce a two-phase flow model which describes the motion of two incompressible fluids. The proposed model is governed by nonlinear partial differential algebraic equations (PDAEs) with open initial-boundary conditions. The well-posedness of the boundaries is analyzed using characteristic curves, which leads to development of a boundary actuation structure that is suitable for...
