Computation of Optimal Structural and Technical Parameters of Solar Dryer

determination of the geometrical measurement and technological parameters of a heliodryer are very important. This study engaged computational modeling using known mathematical relationship and new boundary statements of the problem in relation to the object. The movement of air was acting as drying agent in the dryer and the common heat conductivity equation was considered. According to the presented algorithm in this study, the differential equation was solved with taking into account dimensionless magnitudes (Grasgof, Reynolds and Prandtl).The results were identified as is olines, the function of an isotherm and an isobar current were found at various values of Grasgof, Reynolds and Prandtl numbers. Most efficient heat exchanges zones were recognized by various Nusselt's various values. The effective zone of drying was described graphically ina vicinity of the camera of the dryer, where the passive zone near site of the dryer camera was identified and it was presented also as a graph.
