This study investigates the drying performance and thermal behaviour of a solar dryer that is combined with a flat plate collector and phase change materials. In order to improve the solar collector's thermal efficiency, three distinct designs of the collector were investigated: one without ribs, one with straight ribs, and one with V-shaped ribs. Computational fluid dynamics was also used to model the temperature distribution of the collector under varying conditions of solar radiation throughout the day. Due to the fact that the heat flux intake from the sun is at its peak about one in the afternoon, the highest temperatures of the day have been measured close to that time. The thermal performance of solar collector designs that include ribs has been found to be superior than the performance of solar collector designs that do not include any ribs. The collector with V-shaped ribs produced the highest output temperature, which was 346.679 Kelvin, followed by the collector with straight ribs, which produced 345.262 Kelvin. Both of these temperatures were achieved about 1:00 PM. Both the sun collectors with straight ribs and the solar collectors with V-shaped ribs have obtained a virtually identical maximum temperature of the PCM; specifically, 352.214 and 352.507 K, respectively. The highest possible value of the liquid fraction, namely 0.560582, was found to be reached in the case with V-shaped ribs.
