Investigating the Role of Geometry in Solar Water Heating: A Case Study of Cylindrical and Frustum Buckets

Energy Science &Engineering, Volume 13, Issue 8, Page 4087-4100, August 2025.
ABSTRACT This study studies the effect of bucket shape and geometry on the performance of solar water heating systems. Three plexiglass (PMMA) buckets were chosen: cylindrical, frustum, and inverted frustum. Each bucket has a capacity of 13 L and 3 mm wall thickness.
