The aim of present work is to present and calibrate a new mechanistic model that includes physical and biokinetic processes to reproduce the algae growth in photobioreactor or ponds during long-term scenarios. A COMSOL Multiphysics® model is used to implement the microalgae processes mainly based on River Water Quality Model 1 (RWQM1) (Reichert et al., 2011). The main innovation of the model is ...

Fluid-structure interaction (FSI) refers to a class of problems in which the motions of fluid and solid are coupled. FSI is of great significance in many applications such as aero-elasticity, biomechanics, and design of various engineering systems. Typically, the multiphysics involved in the FSI problems render them too complex to solve analytically, necessitating the use of numerical ...

Electromagnetic Forming (EMF) is a promising and relatively new manufacturing technology having significant advantages over conventional forming processes. A primary characteristic of this process is use of noncontact electromagnetic forces to achieve forming and shaping of various metal work pieces. Mechanically, this is a high-strain rate forming process. From the modeling and simulation ...

Over the last decade, electrowetting-on-dielectric (EWOD) has become one of the most blistering and versatile tool in digital microfluidics. It enables control over fluid shape and flow by electrical signals alone, which is viable by effective utilization of the excess charge accumulation at the interface between the droplet and the dielectric surface, also by polarization of line tension at the ...

Tonal noise from wind turbines can have effects on neighboring residences and its emission can result in strong regulatory penalties that can include the closure of wind farms. The authors present a model of a new broadband damping approach where containers filled with EniDamp™, an Advance Particle Damping (APD) material. The containers, so-called APD pods, are magnetically fixed to wind ...

In this work a modified anisotropic creep model with structure for soft soils was implemented by using the Physics Builder. The model is validated against boundary value laboratory test such as undrained tri-axial tests and CRS (constant rate of strain) tests. The implemented user-defined MAC-s constitutive model seems to capture many of the important behaviors seen in soft soils.

This work examined in detail the a priori prediction of the axial dispersion coefficient from available correlations versus obtaining it and also mass transfer information from experimental breakthrough data and the consequences that may arise when doing so based on using a 1-D axially dispersed plug flow model in COMSOL Multiphysics® software and its associated Danckwerts outlet boundary ...

An external magnetic field imposed on a ferrofluid with a temperature gradient, results in a non-uniform magnetic body force, which leads to a form of heat transfer called thermomagnetic convection. A magnet placed near the device will always attract the colder ferrofluid more than warmer. Viscous, two-dimensional, laminar and incompressible ferromagnetic fluid flow, under the influence of a ...

Simulation of laser pulse-train (25ns, 60 kHz and 3000 pulses) heating Sol-Gel thin film using COMSOL Multiphysics software is investigated. The results show two kinds of temperatures formed on film surface by laser pulse-train heating. One is a single pulse induced transient peak-temperature, which is up to ~1635oC on both Si and glass substrates. The other is the accumulated ...

Seals or gaskets that are compressed between walls of a container are important to many industrial applications. Understanding the performance of such seals requires an understanding of the microscopic geometry of the sealing surfaces, because the fluid seeps around the undulations of such surfaces. This paper presents strong computational evidence that the microgeometry of such surfaces depends ...
