A new method is proposed to study battery thermal behavior under nature convection condition, especially focusing on temperature rising and inhomogeneity of battery. Using porous electrode theory, an electrochemical and homogenization heat source thermal coupling model and an ... Read More

CBM Extraction System Simulation Research

X. Mingjing [1]
[1] China University of Mining and Technology, Xuzhou, Jiangsu, China

Coal mines in many countries which rely heavily on fossil energy have huge CBM, coal bed methane, reserves. Meanwhile, methane extraction efficiency of low permeability coal seam is very low. It causes seriously waste of low-carbon energy source. For the sake of enhancing the efficiency ... Read More

Multiscale Resin Impregnation Modeling in a Bidirectional Composite Laminate

G. Salkar [1], B. Kr Mishra [1], M. Jayaraman [1], S. Manian [1]
[1] National Centre for Aerospace Innovation and Research, Mumbai, India

Resin Transfer Molding (RTM), is a closed mold reinforced polymer composite molding process where the resin is infused under a pressure gradient. The liquid resin is infused through the dry preform and displaces air to saturate the preform. One of the governing parameters in an RTM ... Read More

A Study on Hydrodynamics of Melt Expulsion in Pulsed Nd: YAG Laser Drilling of Titanium
