Mathematical Modeling the Work of Helioroof
Journal Title: Вентиляція, освітлення та теплогазопостачання - Year 2015, Vol 18, Issue
Abstract
This article describes the modeling the worb of helioroof. Helioroof enhances the efficiency of solar heating by increasing the area of the absorption of solar energy. It is shown that heat can be effectively used by roofing material building. Deduced dependence o/temperature o/water in the accumulator box on the intensity of the heat flux and the exposure time. The dependence allows to determine the effectiveness of helioroof under various conditions

Influence of magnetic field characteristics during water treatment on the parameters of capillary-porous and colloidal capillary-porous bodies
Technological systems with water magnetization give unstable results. The reason is a lack of research of the influence of the water magnetization parameters. The hypotheses on expediency of application of high-frequency...
Geometric and Kinematic Analysis of the Turbulence Intensity of Convex Wall Jets
The turbulence intensity in wall jets, laid on a convex surface due to the Coanda effect, is determined on the basis of the geometric and kinematic analysis. The obtained maximum turbulence intensity in a section corresp...
