This paper presents information on techniques needed in COMSOL Multiphysics® to enable computational studies of coupled systems of PDEs for time-dependent non-linear problems. Furthermore, we demonstrate how to use data files as input for initial conditions. To illustrate the techniques, we consider a system of two time-dependent non-linear PDEs from mathematical biology that couples an ...

The pore sizes of many membranes being studied for separating the components in gas mixtures are on the scale of nanometers. Depending on the specific gases and pressures being used, this scale will put the flows in the Transition between Slip Flow and Knudsen regime. The differential flow of the gas components gives the relative diffusion of the gases through the membrane. There are a number of ...

The aim of the present work is to implement in COMSOL Multiphysics a multiphase fluid flow model in porous media, also known in the oil reservoir engineering literature as a black oil model, using a standard finite element approach. In particular, we are interested to apply this model coupled with a multiphase, multicomponent transport model to study Enhanced Oil Recovery processes at laboratory ...

Seals or gaskets that are compressed between walls of a container are important to many industrial applications. In this paper we present a fluid flow model for predicting the sealing performance of such seals. A computational study using COMSOL Multiphysics® software suggests very strong simplifications to the postulated flow equations.

Because of the complex nature of geomaterials and presence of solid and fluid within a single system, it is crucial to consider all the physics involved within the geomaterial system. A fully coupled thermo-hydromechanical model is developed. The model consists of a three-phase flow model designed as a set of coupled PDE application modes that when coupled with the Heat Transfer Module and ...

The dynamic behavior of droplet impingement on a solid surface is important to many engineering applications. This paper studied the dynamic behavior of a droplet impinging onto solid dry surfaces with different surface wettability using the COMSOL Multiphysics® software. The simulation results were validated against experimental results. It was found that the Level Set method can predict the ...

Viscous fingering is a topic of interest since the beginning of computational fluid dynamics. Here we focus on the classical constellation of miscible displacement, as it has been investigated in Hele-Shaw cells. A temperature or salinity front is entering with a fluid that has a different viscosity. The pure 1D flow is destabilized by the Saffman-Taylor instability. Using COMSOL Multiphysics® ...

Selective Laser Melting (SLM) offers great potential for future manufacturing technology. In order to extend its applicability for the processing of high melting materials like molybdenum fundamental process understanding is required. This can be obtained by multiphysical simulations that allow a look into the process. In this contribution a thermo-fluiddynamical simulation model for laser beam ...

This paper deals with the simulation of mathematical model for supercritical extraction. Reverchon, 1996 extracted sage oil using supercritical extraction method from sage leaves at 9 MPa and 50 ᵒC. Four mean size of sage leaves ranging from 0.25 to 3.10 mm were taken for extraction with other experimental conditions and process parameters. Experimental results were fitted in the model developed ...

1. Introduction The topology optimization method is becoming increasingly popular as a design tool for multiphysics systems [1,2]. Topology optimization of fluid-thermal systems has been presented for example in  for forced convective heat transfer and in  for natural convection problems. In this work, topology optimization including density filtering and projection is applied to ...
