Abstract

In this research paper: To increase the energy efficiency of a solar-air heater for solar dryers by the method of airflow turbulization. Research has been conducted on the more efficient use of alternative energy sources. An increase in heater efficiency has been studied by making the airflow turbulent and breaking the boundary layer. A model of a solar air heater was prepared in accordance with the theoretical calculations of the research work. Experimental results have been obtained using the heater model in practice. Optimal operating modes have been investigated to achieve maximum efficiency of the heater. The efficiency of the device for laminar and turbulent flow was calculated. Recommendations for the use of research results have been developed.
