Abstract :
Background: An experimental work was reported to estimate the increase in distillate yield for a compound
parabolic concentrator-concentric tubular solar still (CPC-CTSS). The CPC dramatically increases the heating of the
saline water. A novel idea was proposed to study the characteristic features of CPC for desalination to produce a
large quantity of distillate yield. A rectangular basin of dimension 2 m× 0.025 m× 0.02 m was fabricated of copper
and was placed at the focus of the CPC. This basin is covered by two cylindrical glass tubes of length 2 m with two
different diameters of 0.02 m and 0.03 m. The experimental study was operated with two modes: without and with
air flow between inner and outer tubes. The rate of air flow was fixed throughout the experiment at 4.5 m/s. On
the basis of performance results, the water collection rate was 1445 ml/day without air flow and 2020 ml/day with
air flow and the efficiencies were 16.2% and 18.9%, respectively.
Findings: The experimental study was operated with two modes: without and with air flow between inner and
outer tubes. The rate of air flow was fixed throughout the experiment at 4.5 m/s.
Conclusions: On the basis of performance results, the water collection rate was 1445 ml/day without air flow and
2020 ml/day with air flow and the efficiencies were 16.2% and 18.9%, respectively.
