Dynamic simulation of multiple-effect evaporation

Case Studies in Thermal Engineering, 2022
The main purpose of this work is to simulate multiple-effect evaporation and its variation as a result of the interconnection between batch and continuous unit operations. Therefore, the challenges posed by the hybrid continuous-discrete character of the

Experimental System Identification and Black Box Modeling of Hydraulic Directional Control Valve [PDF]

Modeling, Identification and Control, 2015
Directional control valves play a large role in most hydraulic systems. When modeling the hydraulic systems, it is important that both the steady state and dynamic characteristics of the valves are modeled correctly to reproduce the dynamic ...

Steady-state simulation and optimization of an air cooled chiller

Case Studies in Thermal Engineering, 2022
In this paper, we propose a rigorous model for representing the operation of an air cooled chiller of a large office building and some simple correlations for predicting global heat exchange coefficient and pressure drop of the evaporator.

Steady-State Simulation of Semiconductor Devices Using Discontinuous Galerkin Methods

IEEE Access, 2020
Design of modern nanostructured semiconductor devices often calls for simulation tools capable of modeling arbitrarily-shaped multiscale geometries. In this work, to this end, a discontinuous Galerkin (DG) method-based framework is developed to simulate ...

Grand canonical steady-state simulation of nucleation [PDF]

The Journal of Chemical Physics, 2009
Grand canonical molecular dynamics (GCMD) is applied to the nucleation process in a metastable phase near the spinodal, where nucleation occurs almost instantaneously and is limited to a very short time interval. With a variant of Maxwell’s demon, proposed by McDonald [Am. J. Phys. 31, 31 (1963)], all nuclei exceeding a specified size are removed.

Steady-State-Preserving Simulation of Genetic Regulatory Systems [PDF]

Computational and Mathematical Methods in Medicine, 2017
A novel family of exponential Runge-Kutta (expRK) methods are designed incorporating the stable steady-state structure of genetic regulatory systems. A natural and convenient approach to constructing new expRK methods on the base of traditional RK methods is provided.
