The Method of Hydraulic Calculation of a Heat Exchange Panel of a Solar Water-Heating Collector of a Tube–Tube Type with a Given Nonuniform Distribution of Fluid Flow Along Lifting Pipes

The purpose of this work is to develop a method for the hydraulic calculation of a heat exchange panel of a solar tube collector of a tube type with a given nonuniform distribution of fluid flow under conditions of forced circulation. On the basis of previously obtained design dependencies, a method of hydraulic calculation of a heat exchange panel of a solar thermal collector of a flat-plate type with a given uneven distribution of fluid flow under conditions of forced circulation has been developed. An example of calculation using the developed method is given.
