Flow and heat engineering developments under EFOP-361 project

Abstract

This summary work aims to present the EFOP 3.6.1. research during the project period. One direction of research is to investigate anisotropic turbulence intensities, id est to investigate the distribution of Reynolds stresses and energy spectra in a square cross-section channel, downstream of a semi-active jet turbulence grid generating anisotropic turbulent airflow. In addition to the semi-active jet turbulence grid, another type of turbulence grid was developed and experimentally investigated. The second direction of research investigates the uses of solar energy systems in various applications to define the most appropriate system that has highly efficient and reliable. hybrid solar/thermal systems had proven effective to meet the required loads of electric energy and good capacity to provide thermal energy simultaneously without toxic emissions.
