A 2D transient heat conduction model was created in COMSOL Multiphysics® software to study the performance of photovoltaic-thermal (PVT) water system. The model captures the variation of important environmental and system parameters such as outside temperature, solar irradiation, air velocity and temperature. The model has a good agreement with experimental data for the photovoltaic cell ...

Metal foams are interesting materials with many potential applications. They are characterized by a cellular structure represented by a metal or metal alloy and gas voids inside (Fig.1). A common metallic cellular material is aluminum foam which can be produced metallurgically by heating a precursor, made of aluminum alloy and TiH2 as foaming agent, in a furnace. In this case, the foaming ...

The particle tracking model provided a deeper understanding to the experimental results. The model showed good agreement with experimental data for rotation, transport and attachment. In the attachment model, protrusions create low velocity, low shear regions increasing attachment while holes pull cells toward the surface and increase residence time on the surface increasing attachment rate.

This publication aims to investigate conjugate heat and mass transfer around a clothed virtual manikin. This research can be performed at different scales: (1) at material scale where a piece of textile is investigated in 1D or 2D space or (2) at system level where a clothed cylindrical body (2D) or a complete manikin (3D) is modeled. The work is based on previous methods and results from ...

Heat transfer inside a refrigerated truck is a key phenomenon that governs the temperature inside the truck and the regulation of the cooling system. Up to now, a lot of experimental studies ([Tso et al., 02]) have been carried out to assess the effect of opening the door and to minimize the external heat transfer with fan air curtain. Together with AIR LIQUIDE, the world leader in gases, ...
Boundary conditions in multiphase, porous media, transport models of thermal processes with rapid evaporation

In modeling of thermal processing of biological materials with rapid evaporation, it is critical to provide boundary conditions consistent with the phenomena happening at the surface to accurately predict spatial temperature and moisture content for quality and safety assurance. Boundary conditions in a mathematical model are as important as governing equations itself and describe how the heat ...

In this study, the dam-break type two-dimensional gravitational collapse of rectangular granular piles in air was numerically studied. The frictional behavior of the material was based on the von-Mises model with the Mohr-Coulomb yield surface leading to pressure and strain-rate-dependence of shear viscosity. The governing equations of the problem were solved using the COMSOL two-phase flow CFD ...

Throughout history, the copper pyrometallurgical processes have been carried out mostly in discontinuous or batch systems. In recent decades new continuous technologies have been developed but focused only on Smelting and Converting stages leaving aside the Refining one. In 2002 a novel technology was proposed by the Department of Mining Engineering of Chile University which consists in two ...

The performance of a homogeneous T-mixer can be enhanced significantly by the stimulation of secondary/ transverse flows in the microchannel. Various mixing mechanisms are reported for enhancing micromixing performance such as grooves at the channel bottom, heterogeneous charge patterns etc. Most of these micromixers are studied with respect to planar geometric parameters such as groove width, ...

The paper investigates the hydrodynamic performance of a hierarchical parallel channel network for the objective of optimal thermal coupling to heat released in the adsorption processes, as in adsorption heat pumps. More specifically, the uniformity of the fluid flow over the network is improved by optimizing the topology of the manifold channels of the two hierarchical levels. For this purpose ...
