Heat transfer effects during solidification of semicrystalline polymers
Article Abstract:
The effects of heattransfer on the solidification phase of semicrystalline polymers are investigated. Experiments are carried out wherein two semicrystalline materialswith different crystallization rates are subjected to a specific temperature that promotes isothermal crystallization. The same materials are again studied using a mathematical model. The computational results show good agreement with the experimental observations.

Equivalence between higher-order stress power and heat flux in energy equation based on lattice dynamics
Article Abstract:
Research was conducted to examine the equivalence between higher-order stress power and heat flux in energy equation based on lattice dynamics. The energy equation for sth order micromorphic body with internal constraint was formulated with microscopic quantities of atoms. Results indicate that the divergence of heat flux is equivalent to the total of each power due to higher-order stresses.

Effect of turbulent heat transfer on continuous ingot solidification
Article Abstract:
The interaction between turbulent heat transfer and phase change characteristics during ingot casting is investigated. A theoretical model based modified k-epsilon two-equation turbulence theory and Favre-averaged Navier-Stokes equations are used to account for the fundamental features related to phase change. The results show very good agreement with existing experimental data.
