Dvorets'kyj O. Geometrical simulation of the reflected power flows in solar thermal technology.

The dissertation is devoted to development of the reflected power flows description theory by means of applied geometry for maintenance of concentration and catching of the reflected solar flow at the motionless concentrator and with changing direction of the radiation flow. In a basis of theoretical development the features of surfaces of the reflected beams along sections of concentrators lay, on which congruence of the reflected beams is stratified. With the purpose of an assessment of a concentration picture the concept about quasifocal points and lines as points and lines of maximal concentration is determined. The algorithms of the quasifocal line description for surfaces of concentrators as canal and cyclic surfaces, surfaces of rotation are offered that considerably simplifies researches of a spatial picture of reflection. The geometrical model forming of a reflecting surface on a given quasifocal curve is offered. That presents the ample opportunities in designing of concentrating systems in v iew of required parameters of a concentration zone.
