Practical considerations for low pressure solar water heaters in South Africa

open access: yesJournal of Energy in Southern Africa, 2014
This paper presents the results of the design parameters that affect natural convection of Low Pressure (LP) Solar Water Heaters (SWH) in South Africa. Fluid flow plays an important role in the heat transfer process associated with natural convection. Three partial differential governing equations were considered.
