Thermal Performance and Heat Loss Analysis of Parabolic Concentrating Collector
Аннотация
The present work examines an experimental investigation of
thermal performance and heat loss analysis of parabolic
concentrating collector (PTC) with twisted tape (TT) inserts
in the absorber tube for different twist ratios (4.5, 5.5, 6.5,
7.5, 8.5 and 9.5). The experiment is conducted using water as
the heat transfer fluid and the mass flow rate ranges from
0.0249 kg/s to 0.0590 kg/s. Instantaneous efficiency and
useful heat gain for the absorber tube with twisted tape
inserts are found comparatively higher than the same results
obtained from the plain absorber tube one. On the other hand,
heat losses decrease for the absorber tube with twisted tape
inserts as compare to the plain tube one.
