The goal of the project is to get deeper understanding of the fluid dynamics and heat transfer phenomena taking advantage of the new computing resources in parallel computation using loosely coupled parallel computers (Beowulf clusters). According to the most appropriate techniques for their parallelization, the codes/software to be developed within this project for the treatment of the different phenomena of interest have been grouped into three main areas: i) detailed resolution of turbulent incompressible flows based on DNS and LES methodologies, ii) resolution of flows with (approximately) parabolic spatial structure (cases of combustion, free surfaces and flow between plates will be of special interest); iii) resolution of flows with elliptic structure (turbulent flow in general with RANS models and moving surfaces). Although the project has essentially a basic/fundamental nature, the potential applications are addressed to the simulation of thermal systems and equipment of industrial and social interest in which the milestones achieved in this basic research line are applicable. Thus, the experience acquired will allow not only to maintain and improve the technology transfer to the companies with which the Group collaborates in the framework of research contracts and/or national and European research projects, but also to increment the possibilities of application to other companies and industrial and social sectors.

1 Project objectives
1.1-Introduction This project focuses on the continuation of the work that the Group is carrying out in the framework of its main research line: “Numerical simulation and experimental validation of heat and mass transfer phenomena; application to the design of thermal systems and equipment”. Starting from the know-how and numerical facilities developed by the Research Group, and as a continuation of previous TIC projects, the goal of the project is to get deeper understanding of the
