This study analyzed the laser powder bed additive manufacturing process. The laser is modeled as a moving heat source with time dependent heat transfer causing local, transient melting of the metal powder. Heat transfer is considered to take place due to convection in the molten metal ... Read More
This work investigates the frequency-dependent electrothermal behaviors of freestanding doped-silicon heated microcantilever probes operating under the periodic (ac) Joule heating. The transient heat conduction equation for each component (i.e., the low-doped heater region, the high ... Read More
Ultrafast terahertz photoconductor devices, especially photomixers, are usually limited in output power by device failure thought to be caused by excessive temperatures. Therefore, understanding of thermal breakdown is essential to the study of device reliability and failure of ... Read More
An analysis to quantify the effects of packed bed channeling in the narrow passages of the ISS (International Space Station) CDRA (Carbon Dioxide Removal Assembly) is presented. The CDRA contains two pelletized adsorbent beds to remove CO2 respired by the crew. Each CO2 adsorbent bed is ... Read More
It is frequently necessary to electrically heat gases; a convenient geometry is the familiar tube-in-shell heat exchanger, where the tube side is modified for electrical heater-rods, and the baffled shell side contains the flowing gas, as indicated in Fig. 1. However, this modification ... Read More
Catalytic micro-combustor represents an exciting area of research for portable power generation. Extensive research is being currently conducted on the design of the reactor and catalyst selection [1]. However another critical element of the design will be a recuperator to minimize ... Read More
The numerical study of temperature and acceleration sensitivities of a dual cavity Fabry-Perot (FP) interferometer is carried out using finite element method. The optical cavities are formed by machining two side-by-side circular bore of 12 mm each on a monolithic block of low expansion ... Read More
A 3D finite element analysis is carried out, using COMSOL® software, to reproduce the thermal profile obtained with Rosenthal’s equation. The implemented heat transfer equation has been modified as a means to approximate Rosenthal’s solution. An analysis of the differences between the ... Read More
Neste trabalho é analisado o comportamento dos perfis de temperatura e umidade e sua penetração em bobinas de papel submetidas a longos períodos de armazenagem. O modelo considera a transferência simultânea de calor e massa com o efeito Soret, mas sem o efeito Latour. O sistema é fechado ... Read More
This work proposes the use of inverse problem techniques in connection with COMSOL to estimate the heat flux and the temperature field on a turning cutting tool in transient regime. The main purpose of the present work is to present the improvements performed in relation to the authors’ ... Read More
