Transport Phenomena

A transient three-dimensional heat and mass transfer model is developed for a semi-transparent optically large, non-uniform and non-isothermal particle exposed to an external source of high-flux irradiation and undergoing chemical reaction. The model couples radiation, conduction and convection...

Thermochemical water splitting presents a way to store thermal energy in the chemical bonds of a H 2 molecule. Besides becoming an increasingly important energy carrier, hydrogen already has vast importance in petroleum upgrading and ammonia synthesis. In an effort to improve the Sulfur-Iodine...

Pyrolysis oils derived from lignocellulosic feedstocks by way of fast pyrolysis offer the possibility of a distinct alternative to the use of petroleum-based fuels. However, an inherent drawback associated with pyrolysis oil its high oxygen content which is due to the nature of the lignocellulosic...

Arzamendi 1 , I. Uriz 1 , P.M. Diéguez 1 , M. Montes 2 , M.A. Centeno 2 , J.A. Odriozola...

Incineration of wastes and combustion of chlorine-rich coal are the major sources of local and global environmental pollution related to hydrogen chloride (HCl) emission. At the same time, HCl is a common tail gas in chemical industry such as PVC and Freon production. HCl is regarded as the most...

Removal of heat from confined cabins and space habitats is of immense importance to NASA in order to ensure proper thermal control. The design of important thermal subsystems for future applications as in boilers, condensers, evaporators, heat exchangers etc will involve complicated fluid flow...

The study of transport phenomena is an important area of chemical engineering. In many ways it differentiates chemical engineering from other disciplines, such as biomedical and material engineering. In this lecture, Dr. Morton Denn tracks the development of transport in the chemical engineering...
