The knowledge of the electric current density distribution generated by an electrode array is very useful in electrotherapy for tumor treatment. We propose an innovative mathematical approach that takes into account planar solid tumor elliptic geometry, electrical differences between it and its...

The development of SCAM, a three-dimensional numerical model for the prediction of airflow and scalar dispersion in urban canyons, has been described [3]. The first application of SCAM [4] was to study the dispersion of carbon monoxide emanating from car exhausts, but the long term aim has been...

We study the cooling system for submersible electric pumps. This study aims to provide some guidelines to improve the existing cooling system of these electric pumps when they work partially or totally not immersed in the service fluid. Note that inefficient cooling systems cannot prevent the...

A population balance model is presented for describing the direct particle-to-particle heat transfer in fluid–solid processing systems. In developing the model, simple kinetic equations are assumed to describe the heat transfer process, but the particle–particle interactions are considered...
