Scramjet inlet design remains as a key aspect for hypersonic flight. To assess the inlet design, the performance parameters namely; air-capture ratio, total pressure efficiency, inlet drag coefficient, and kinetic energy efficiency are evaluated and analysed. In the current study ... Mehr lesen
In this study the flow through a tube filled with highly porous aluminium foam of three different pore sizes is analysed using COMSOL Multiphysics® CFD Module and compared to experimentally determined pressure drop data. Analyzing the flow through an array of pores allow the deduction of ... Mehr lesen
Phosphoric acid doped polybenzimidazole (PBI) membranes are commonly used in today’s high-temperature polymer-electrolyte-membrane (HTPEM) fuel cell technology. COMSOL Multiphysics is used to model and simulate the three-dimensional, single-phase, non-isothermal overall cell behaviour ... Mehr lesen
Aging infrastructure requires frequent inspections to assess their structural integrity. However, the large amount of existing infrastructure, and the distance between these structures present significant challenges to inspectors. Acoustics-based technologies represent a simple, and ... Mehr lesen
Granular materials have been conventionally used for acoustic treatment due to their sound absorptive and sound insulating characteristics. An emerging field is the study of acoustical properties of multi-scale porous materials. An example of these is a double-porosity granular material ... Mehr lesen
COMSOL Multiphysics software, when properly configured, can readily solve modeling problems in the laminar flow regime using the standard Navier-Stokes equations or in the fully turbulent flow regime using the kappa-epsilon model. Failure to solve a particular model is typically ... Mehr lesen
COMSOL is finite element modeling software capable of solving partial differential equations. This capability allows for the modeling of boundary value problems, which is necessary to the study of light and the properties of light propagation. For this study, we are modeling Fraunhofer ...

The Constrained Vapor Bubble is a fundamental fluid mechanics experiment that is scheduled to run aboard the International Space Station starting in August 2009. The experiment is focused on looking at evaporation and condensation processes at the contact line, where vapor, liquid and ... Mehr lesen
We investigate a prototype concept of a back-up electricity device where we use liquid formic acid (FA) to produce a mixture of carbon dioxide (CO2) and hydrogen (H2) which is used in a PEM fuel cell, Fig. 1. In the fluidized bed reactor the liquid FA is decomposed to a gaseous mixture ... Mehr lesen
To investigate the thermal-mechanical behavior of oceanic transform faults, we calculate 3-D steady-state incompressible mantle flow and heat transport using COMSOL Multiphysics. Our model incorporates a nonlinear viscous rheology with a visco-plastic approximation to simulate ... Mehr lesen
