A new coalescence model for droplets with different mixture composition is developed and implemented inspray calculations. This model is based on an extension of Brazier-Smith et al.'s model (1972) for two colliding droplets withdifferent densities. Based on the rotational kinetic and surface energies of a system of two droplets, coalescence efficiency fortwo colliding droplets with different densities is formulated. In the case of grazing collision, the effect of density of dropletsis also included. The new droplet coalescence model is examined for evaporating and non-evaporating diesel sprays. Validation studies were carried out for both cases and the results were compared with available experimental data. The modelshows good predictive capability and was demonstrated to improve the accuracy of multi-phase flow simulations

Potentials of porous materials for energy management in heat exchangers – A comprehensive review
Rashidi, Saman,Kashefi, Mohammad Hossein,Kim, Kyung Chun,Samimi-Abianeh, Omid ELSEVIER 2019 APPLIED ENERGY -BARKING THEN OXFORD- Vol.243 No.-
<P><B>Abstract</B></P> <P>Heat exchangers are recognized as popular thermal devices with various and important applications in industrial energy systems. Many techniques were employed in order to manage the energy in these devices. Among these techniques, porous materials with high potentials for the energy management and enhancing the thermal performances in heat exchangers were employed widely. This paper reviews recent developments and utilisation of different types of porous materials in the heat exchangers. Both simulation and experimental works were briefly explained. The gaps in current literatures and designs were investigated and solutions for them were discussed.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Potentials of porous materials in the heat exchangers are reviewed in this paper. </LI> <LI> Both simulation and experimental works are briefly explained. </LI> <LI> Gaps in current literatures are investigated and solutions for them are discussed. </LI> <LI> Porous media with larger porosity and conductivity are proper for heat exchangers. </LI> <LI> Fouling in porous materials can provide some negative effects in heat exchangers. </LI> </UL> </P>
