This study aims to calculate the anharmonic thermal expansion (TE) coefficient of metal crystals in the temperature dependence. The calculation model is derived from the anharmonic correlated Debye (ACD) model that is developed using the many-body perturb... see more

This paper presents a thermal based modified dynamic model of a Solid Oxide Fuel Cell (SOFC) for grid-connected systems. The proposed fuel cell model involves ohmic, activation and concentration voltage losses, thermal dynamics, methanol reformer, fuel ut... see more

Our study concerns the modelling of the thermal exchanges by convection in an enclosure. We describe the experimental method used based on fluxes and heat exchange phenomena. The effect of the walls temperature on the thermal equilibrium of the cavity is ... see more

The outcome of radio frequency thermal ablation (RFTA) is significantly affected by the tissue electrical conductivity; thus, understanding the changes of this property during heating is fundamental to suitably model the medical procedure. In this work a ... see more

Paper presents of some aspects of thermal physics necessary for the development of small-scale solar cookers by developing a computational semi-empirical thermal model. The free parameters of the models are adjusted with data obtained from an experimental... see more

The article introduces artificial neural network model that simulates and predicts thermal conductivity and particle size of propylene glycol - based nanofluids containing Al2O3 and TiO2 nanoparticles in a temperature rang 20 - 80oc. The experimental data... see more

This review paper deals with the analytical nanofluid thermal conductivity models published by different research groups. It also summarizes the contrary opinion on anomalous thermal conductivity of nanofluids by different research groups. Basically all n... see more

Solar thermal energy (STE) technology refers to the conversion of solar energy to readily usable energy forms. The most important component of a STE technology is the collectors; these absorb the shorter wavelength solar energy (400-700nm) and convert it ... see more

In this paper, a thermal-baseddynamic model of a Solid Oxide Fuel Cell under different direct current loadconditions is improved by using our previous developed fuel cell model, whichincludes ohmic, activation and concentration voltage losses, thermal dyn... see more
