Simulation of the Acoustic Environment for the Manufacture of Graded Porosity Materials by Sonication

C. Torres-Sanchez, and J. R. Corney
University of Strathclyde, United Kingdom

Many materials require functionally graded cellular microstructures whose porosity is engineered to meet specific requirements of diverse applications. It has been shown in previous work that the bubble growth rate of a polymeric foam can be influenced by the surrounding acoustic ... Per saperne di più

[2]Department of Chemical Engineering, Virgili University, Tarragona, Spain

Steam Reforming of Ethanol using a Catalytic Wall Reactor (CWR) was successfully studied using COMSOL Multiphysics. A mathematical model was used to describe the reactor performance in terms of the main variables and dimensionless groups. Simulations showed that at specified conditions ... Per saperne di più

A Finite Element Analysis on the Modeling of Heat Release Rate, as Assessed by a Cone Calorimeter, of Char Forming Polycarbonate

D. Statler[1], and R. Gupta[2]
[1]Mid-Atlantic Technology, Research and Innovation Center, South Charleston, WV, USA
[2]Department of Chemical Engineering, West Virginia University, Morgantown, WV, USA

During the pyrolysis and combustion of polymers, heat is released and is typically measured with a cone calorimeter to better assess the polymer’s flammability. Modeling heat release rate, as assessed by cone calorimetry, has not been extensively studied for char-forming polymers, such ... Per saperne di più
