Control of Natural Convection Flow for Optimize the Performance Solar Dryers

Abstract:

The purpose of this research to optimize the performance of solar dryers. Optimizing the performance of solar dryers can be done by observing the effect of natural convection flow controls to change the performance of solar dryers. Experimenting performed by the direct measurement method. In the solar dryer made in space collector inlet and outlet of the drying chamber. There are two outlet on the bottom and the top of the drying chamber. Natural convection flow control is done by adjusting the three variations (full open, half open and full close) openings on the upper outlet of the drying chamber. For the most accurate results, testing was conducted simultaneously three kinds of variations of openings using three solar dryers. The results show that optimal conditions of the solar dryer is in the half open position of the outlet flow natural convection.
