Numerical assessment of mass conservation on a MAC-type method for viscoelastic free surface flows
(2012-12-01)
A numerical study of mass conservation of MAC-type methods is presented, for viscoelastic free-surface flows. We use an implicit formulation which allows for greater time steps, and therefore time marching schemes for ...

Application of the PTT Model to Axisymmetric Free Surface Flows
(Amer Inst Physics, 2013-01-01)
This work is concerned with numerical simulation of axisymmetric viscoelastic free surface flows using the Phan-Thien-Tanner (PTT) constitutive equation. A finite difference technique for solving the governing equations ...
Model-Free Predictive Current Control of a Voltage Source Inverter
(Institute of Electrical and Electronics Engineers, 2020-11)
Conventional model predictive control (MPC) of power converter has been widely applied to power inverters achieving high performance, fast dynamic response, and accurate transient control of power converter. However, the ...
A comprehensive kinetic simulation of different types of plant fibers: autocatalytic degradation mechanism
(2019-08-15)
Kinetic analysis of the non-isothermal degradation of three different plant fibers has been performed using isoconversional model-free methods, model-fitting methods in order to establish if different kinetic approaches ...
A Numerical Study of the FENE-CR Model Applied to a Jet Flow Problem
(Amer Inst Physics, 2013-01-01)
The FENE-CR model is investigated through a numerical algorithm to simulate the time-dependent moving free surface flow produced by a jet impinging on a flat surface. The objective is to demonstrate that by increasing the ...
Three-dimensional transient complex free surface flows: Numerical simulation of XPP fluid
(2013-05-01)
In this paper we present a finite difference MAC-type approach for solving three-dimensional viscoelastic incompressible free surface flows governed by the eXtended Pom-Pom (XPP) model, considering a wide range of parameters. ...
