The Atmosphere Revitalization Recovery and Environmental Monitoring (ARREM) project was initiated in September of 2011 as part of the Advanced Exploration Systems (AES) program. Under the ARREM project, testing of sub-scale and full-scale systems has been combined with multiphysics computer simulations for evaluation and optimization of subsystem approaches. In particular, this paper describes ...

Over the last years, the concrete technology has progressed in order to improve the quality of its use and mechanical performances. Despite the technical development known in the context of concrete, the esthetic aspect remains weakly treated. Among the esthetic problems, there is the formation and dispersion of air bubbles (Bugholes) inside the concrete during the concreting process. An ...

As known, air quality in urban areas is dramatically affected in particular by the noteworthy presence of respirable suspended particulate matter (such as PM2.5), nitrogen oxides (NOx), carbon monoxide (CO) and hydrocarbons (HC), which are mainly due to traffic-induced emissions. On the other hand, it is also known that vegetation can help restoring the environmental quality of dense urban areas ...

Laminar flow static mixers are accurate, inexpensive fluid mixing devices that can handle a wide range of fluids and mixing proportions. They have a wide range of industrial applications, especially in the consumer product, pharmaceutical, biomedical, and petrochemical industries. A good mixing quality is obtained when the outlet of the mixer has no concentrated volumes of either mixed materials ...

Dissolution of calcite plays an important role in various processes such as enhanced oil and gas recovery, CO2 sequestration, and groundwater transport for the drinking water production. Dissolution rates predicted by pore scale and continuum scale models are often faster than the observed laboratory rates (Molins et.al., 2014). This discrepancy suggests that the importance of pore scale ...

An important part of the society considers an increased share of renewable energies as an integral part of a strategy towards a sustainable future. As far as heat supply is concerned, this can be achieved using solar thermal collectors, borehole heat exchangers or trough the combustion of biomass. This article shows two applications of two configurations of twisted conduit inside the external ...

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 ...

Wine quality is strongly dependent on the operation parameters of the production process. In batch or fed batch reactors, the rotating velocity should be carefully controlled to avoid cellular stress and ensure adequate mixing of the mixture. Moreover, precise control of substrates concentration evolution and cellular growth, as well as efficient heat transfer, allows the production of high ...
A Research of Electro-thermal Coupling Model for Lithium-ion Battery with Multiphysics in COMSOL Multiphysics®

A new method is proposed to study battery thermal behavior under nature convection condition, especially focusing on temperature rising and inhomogeneity of battery. Using porous electrode theory, an electrochemical and homogenization heat source thermal coupling model and an electrochemical-distributed heat source thermal coupling model are established. In the meanwhile, to improve inhomogenity ...

The Lévêque problem is an idealized simple situation concerning the influence of the boundary on the distribution of temperature or mass in Hagen-Poiseuille flow. Here, the performance of numerical solutions is examined for a range of Péclet numbers, spanning 11 orders of magnitude. We examine the Sherwood, resp. Nusselt numbers and confirm the cubic square rule for high flow ...
