METHODOLOGY FOR DETERMINING GEOMETRIC PARAMETERS OF ADVANCED SOLAR DRYER ELEMENTS
Abstract
This article proposes a method for choosing the shape of a direct type solar dryer. As an example, a parallelepiped shape with non-isosceles triangular bases was chosen for a solar dryer. The working surfaces, from which solar radiation comes on the surface of the material to be dried, are inclined with respect to the horizon by 38 and 52 degrees, respectively, to the northern latitude of the region. Concepts were selected, on the basis of which a computational computational method was developed and the geometric dimensions of the elements of a direct type dryer were determined. The formula for the ratio of the dimensions of the height to the length and, accordingly, to the width of the dryer has been established, and a method for determining the dimensions of the dampers has been developed, designed for the flow of air from the environment into the chamber and for the exit of the vapor-air mixture from the inside of the chamber of the dryer into the environment. This method of selecting the dimensions of the dryer elements creates an optimal mode of their operation, and also creates a natural convection air circulation inside its chamber.
