Empirical Investigation and Analyzing the Thermal Efficiency of Solar Water Heaters Using Evacuated Tubes and Heat Pipes, Considering Multiple Variables and Nanofluid Applications
The effective utilization of solar radiation is one of the most potential solutions for numerous environmental problems. An effective way to absorb solar radiation as well as convert it into thermal energy is by employing a solar water heater. This research investigates an “Evacuated tube heat pipe solar collector” (ETHPSC) performance by examining the impact of various concentrations of nanoparticles in heat pipe's working fluid. Water along with different concentrations of MWCNT (multiwalled carbon nanotube) nanofluids had been employed as the heat pipe's working fluids in the two-step process. Furthermore, impact of different filling ratios, inclination angles, along with flow rates was examined and discussed. According to the findings, the collector's efficiency rose as mass flow rate dropped. In comparison with the other collectors, the heat pipe solar collector with water along with MWCNT (0.2 wt.%) nanofluid is more efficient. Furthermore, as filling ratio rises and angle of inclination declines, the performance improves.
