Project

Study of heat transfer by convection and radiation in conditions with high temperature gradients (MEB0810004)

This project is aiming to contribute to the improvement of prediction of thermal fields in materials in fire conditions. It will be achieved by help of analysis of convection and radiation heat transfer in materials subjected to hig...
