The information gathering from BASNs will provide a significant opportunities for various medical applications. One of the key ... En savoir plus

Coupled Optical and Thermal Modeling of Novel Solar Thermal Collectors

A. Hassanzadeh [1], Y. Bhusal [1],
[1] University of California - Merced, Merced, CA, USA

In the present study, the performance of the two novel solar thermal collectors are modeled using COMSOL Multiphysics. Firstly, Parabola and seagull geometries are utilized as primary and secondary reflector with high concentrator(50X) for high temperature application (650°C). Secondly ... En savoir plus

Catalytic Oxidative Dehydrogenation of Propane to Propylene

E. B. Ledesma [1],
[1] University of St. Thomas, Houston, TX, USA

Propylene is the second most important olefin and the second largest volume industrial chemical produced globally. In 2015, the global demand for propylene was about 94 million metric tons. The largest use for propylene is the production of polypropylene, consuming 67% of propylene ... En savoir plus

A Multi-phase Heat Transfer Model of Cooling Lava

M. E. Rumpf [1], K. Williams [1], L. Kestay [1],
[1] Astrogeology Science Center, U.S. Geological Survey, Flagstaff, AZ, USA

Field observations suggest that two-phase "heat-pipe" processes are active around magmatic intrusions. We are numerically testing the viability of this process around a volcanic sill, embedded in wet sediment. The model focuses on the heat transported by water in the vapor and liquid ...

[1] CanmetENERGY Research Centre, Natural Resources Canada, Ottawa, ON, Canada

Solar energy storage has been an extensive research topic among the several thermal energy applications over the past three decades. Thermal energy storage (TES) systems in general, improve the energy efficiency of systems and sustainability of buildings by reducing the mismatch between ... En savoir plus

Using the COMSOL Multiphysics® software for simulation of TEGs for Waste Thermal Energy Harvesting

L. Howard [1], D. Tafone [2], D. Grbovic [1], A. Pollman [1],
[1] Naval Postgraduate School, Monterey, CA, USA
[2] Ramapo College of New Jersey, Mahwah, NJ, USA

Navy systems, such as turbine engines, produce large quantities of thermal energy. This energy is a byproduct of the work produced by the engine during operation and is typically rejected to its surroundings. The temperature difference between the turbines and the ocean is substantial ... En savoir plus

Thermal Bridging Calculation of Three Steel Stud Wall Assemblies with Benchmarking

M. Ghobadi [1],
[1] National Research Council Canada, Ottawa, ON, Canada

As a part of the Pan-Canadian framework for clean growth, Canada is intent on meeting its 2030 emission targets for which 17% of Canada’s total Green House Gas emissions come from buildings. Given this challenge, emphasis is being placed on developing building designs having greatly ... En savoir plus
