A problem of damage prediction in aircraft structure and its non-destructive evaluation is very important for aircraft structural health assessment. The analysis of the features of direct impact of thin-walled laminate component of aircraft was performed by COMSOL Multiphysics software. Mainly the GFRC and CFRC laminates were selected in form either thin separate plate or sandwich structure. The ...

Modular orthopaedic devices are a feature of total joint replacements today. These modular orthopaedic devices allowing surgeons to choose from a variety of available implant sizes, designs & material options for the procedure required and the patient specific requirements. However, even though this allows for greater scope of implant construction, if the various components of the modular design ...

The dynamic behavior of cable supported bridges subjected to moving loads and affected by corrosion and accidental failure mechanism in the cable suspension system is investigated. The different types of cable supported bridges are distinctively characterized by the configuration of the cable system . The suspension system comprises a parabolic main cable and vertical hanger cables connecting ...

This paper will describe some applications of COMSOL Multiphysics to the analysis of Frequency Selective Surface (FSS) structures. Particular attention will be devoted to the possibility of designing a stealthy antenna using the FSS structure. In fact, since it possesses a dual filter concept of frequency and polarization for electromagnetic wave, the Radar Cross Section (RCS) of the antenna is ...

Introduction: Medium voltage reclosers are representing nowadays an important link between transmission power systems and low voltage grids. With a high level of renewable energy penetration, the medium voltage networks are becoming bidirectional. Therefore, the associated switching devices must ensure the protection of newer types of power systems as well as new types of loads. The optimal ...
Sulfur Deactivation Effects on Catalytic Steam Reforming of Methane Produced by Biomass Gasification
P. Sadooghi, R. Rauch
Vienna University of Technology, Vienna, Austria
Sulfur, which is incorporated in the biomass structure, is released into the product gas during gasification as hydrogen sulfide. Hydrogen sulfide is known to deactivate nickel based steam reforming catalysts by chemisorption on the metal surface during steam reforming process. Desulfurization has a negative effect on the process efficiency therefore steam reforming has to be run without ...

This paper presents the electrical and thermal analysis of an OLED module. The OLED module consists of the OLED tile and the DC-DC converter incorporated in its backplane. The DC-DC converter is realized as an integrated circuit and its inductor is embedded in the the backplane. The DC-DC converter is highly efficient, but a fraction of the electrical power is dissipated in the integrated circuit ...

Results presented are a contribution to the design of a 5kW-DC-AC-converter for applications in forklifts. The device is located in a closed environment and entirely operated with passive cooling. Due to concurrent engineering approach and environmental conditions correct prediction of absolute temperature values by simulation was crucial. Heat sinks have been modeled properly and a thermal ...

This study deals with a numerical investigation of the melting process of a PCM in a rectangular enclosure differentially heated. COMSOL Multiphysics is used in order to numerically solve Navier-Stokes and energy equations in the considered system. Adopting an enthalpy formulation, one single equation is used to solve transient conduction and convection heat transfer in both the solid and liquid ...

This paper presents thermo-mechanical models for predicting the strength of polymer laminates loaded in tension or compression exposed to one-sided radiant heating by fire. The first part is the fire simulation where the FDS model is utilized. The FDS model generates a solution of several state variables, such as pressure, temperature, heat, velocity vector. In the second part, COMSOL heat ...
