Investigation of hydrodynamic processes in tubes of a combined solar collector
Аннотация
The use of solar energy in technological processes in heat and humidity air treatment systems is an urgent problem. The aim of the work is an experimental study and substantiation of the parameters of the hydrodynamic regime of the developed combined solar collector in the turbulent regime of air flow for the systems of heat and moisture treatment of air in greenhouses. Experimental studies to determine the hydraulic resistance in smooth pipes of a combined water-air solar collector are presented. Based on the processing of experimental data, empirical dependencies were obtained to determine the hydraulic resistance in turbulent modes of water movement. The obtained experimental results serve to optimize the parameters of the combined solar collector.
