TL;DR: In this article, an experimental investigation of heat transfer and friction factor characteristics of thermosyphon solar water heater system with full-length twist, twist fitted with rod and spacer fitted at the trailing edge for lengths of 100, 200 and 300 mm for twist ratio 3 and 5 has been carried out and compared with plain tube collector for the same operating conditions.

TL;DR: In this article, an experimental investigation of heat transfer, friction factor and thermal performance of twisted tape solar water heater with various twist ratios has been conducted and the results are compared with plain tube collector for the same operating conditions with Reynolds number varied from 3000 to 23,000.

TL;DR: In this article, an experimental investigation of heat transfer, friction factor and thermal performance of thermosyphon solar water heater system fitted with helical twisted tape of various twist ratios has been performed and presented.

TL;DR: The proposed internal model control with optimal H2 minimization framework is proposed in this paper for design of proportional-integral-derivative (PID) controllers and provides enhanced closed loop performances when compared to recently reported methods in the literature.
