| Summary: | An alternative design receiver of parabolic trough
collector (PTC) has been discussed in the present study. The
three passes design (3p) receiver made from copper and
coated with selective black paint was studied and optimized
experimentally. Mass flow rates were varied alongside
number of days. The proposed design was compared with the
PTC equipped with smooth receiver (SM). The
aforementioned variations resulted in the experiments
performed in September 2018. The 17th, 18th, 19th, and 20th,
were chosen for the PTC with smooth receiver, while 25th
,
26th, 27th, and 28th were for the receiver with three passes).
The solar irradiances for these days were similar. The heat
transfer fluid (HTF) was fuel oil. Mass flow rates of 2, 2.5, 3,
3.5 LPM were observed alongside change in number of days
for the experiment. The results show that the PTC with three
passes receiver achieved higher average thermal efficiency
and average useful energy than the PTC with smooth receiver. |
