Article Type: Guest editorial From: International Journal of Numerical Methods for Heat & Fluid Flow, Volume 25, Issue 6.

This Special Issue collects selected papers presented at the Third International Conference on Computational Methods for Thermal Problems (ThermaComp 2014, web site: www.thermacomp.com) held in Lake Bled, Slovenia, between 2 and 4 June 2014. ThermaComp series aims at bringing together researchers interested in fundamental numerical methods for heat and fluid flow and those who use such methods to solve complex, real-life applications. This Special Issue includes some of the work presented by invited lecturers, other leading scientists in the field and R.W. Lewis award winner.

In the first paper of this first volume of the Special Issue, Cotta and co-authors use the Generalized Integral Transform Technique for the analysis of conjugated heat transfer in micro-heat exchangers (Knupp et al., 2015). Seetharamu and co-authors present a finite element simulation of a three fluid heat exchanger (Veerabhadrappa et al., 2015). Lamoureux and Baliga present a hybrid numerical method for simulations of a closed-loop thermosyphon operating with slurries of a micro-encapsulated phase-change material suspended in distilled water (Lamoureux and Baliga, 2015). Nonino et al. (2015) propose a simplified and accurate finite element procedure for the analysis of the conjugate conduction-convection heat transfer in cross-flow micro-heat exchangers. Joshi et al. (2015) illustrate the challenges and possible modelling approaches for the co-optimization of electrical power and thermal management in information technology systems. Liu and co-workers present an adaptive GSM-CFD solver based on the gradient smoothing method for compressible turbulent flow simulation (Yao et al., 2015). Karimpour Ghannadi and Chu (2015) analyse the performance of a numerical method for the solution to shallow-water equations on a staggered grid in simulations for shear instabilities at two convective Froude numbers. Chinesta and co-workers propose an advanced solution of the parametric non-linear model related to the Rayleigh-Benard laminar flow based on proper generalized decomposition (Aghighi et al., 2015). Codina et al. present a finite element approximation of the low Mach number equations coupled with radiative equations to account for radiative heat transfer (Avila et al., 2015). Dulikravich et al. present a numerical simulation of cooling systems with simultaneous internal and external liquid cooling as a method to extend the usable life of human hearts (Abdoli et al., 2015). Costa et al. (2015) present a new methodology for the optimization of the performance of incinerators plants based on numerical simulation. Finally Mavrič and Šarler (2015) present an extension of the Local Radial Basis Function Collocation Method for the solution of heat transfer, fluid flow, and electromagnetic problems to thermoelastic problems.

We thank the authors for accepting our invitation to contribute their interesting work to this Special Issue. We are grateful to R.W. Lewis for continuing to support ThermaComp and giving us the opportunity to edit this Special Issue.
