Abstract

There has been wide scale adoption of evacuated tubular solar water heaters in China, Europe and recentlyinIndia. Factors limiting the performance of this type of product have been evaluated. A numerical model of theheat transfer and fluid flow inside a water-in-glass tube has been developed to investigate the heat extractionfrom the long collector tubes and the flow structure inside the tube. The effect of diameter of evacuatedtube, length of evacuated tube, angle of tilt of evacuated tube and tank diameter on the natural circulation loopandheat extraction has been analysed. An attempt has been made to optimise the dimensions and configurationof the system using Computational Fluid Dynamics too with the help of ANSYS FLUENT® software.
