The problems of how to optimize the geometric parameters of the paraboloid-cylinder-receiver (PC-R) system of thermal power plants are examined. The optimal opening angles of the paraboloid-cylindrical concentrator in the system are determined, and i

The electron-microscopic analysis of extranuclear variegated forms of sunflower demonstrated that plastids from white leaf areas are practically devoid of inner membrane structures. The mutants and the initial (wild-type) green line were compared by

The problem of whether it is possible to increase the concentration of solar radiation in parabolocylindrical concentrators (PCC) with the help of a secondary concentrator of the “focusing wedge” (FW) (foclin) type has been examined. It is found

It is shown that in the paraboloid-lens system the limiting solar radiation concentrations at the output and at the medium-air interface do not exceed their thermodynamic limit in the air. At the same time the lens as a secondary concentrator (SC) ha

A generalized nonstationary numerical heat model of a solar air-heating collector (SHC) with smooth channels is developed. The results of the investigations make it possible to establish several requirements relating to the constructive parameters of

Results are presented of numerical-experimental investigations of convective heat exchange in solar “hot box” (HB) slots. It is shown that it is possible to use the infinite volume formulas to describe convective heat exchange in the HB, which ma
