Abstract
The other experiments were carried out for studying the performance of the
modified solar distiller and comparing its performance with a conventional solar
distiller for the same water depths and for water depths of 2 cm and 3 cm.
Thus, two experiments were carried out. First, the water basin depths were 2 cm
and 9 cm for the two conventional distillers and 9 cm for the modified distiller. In the
second experiment, the water depths were 3 cm and 10 cm for the two conventional
distillers and 10 cm for the modified one.
The accumulated productivities for conventional distiller with water depth of 2
cm, conventional distiller with water depth of 9 cm and modified distiller with water
depth of 9 cm were 1.48667 (lit/day), 1.67333 (lit/day), and 1.75333 (lit/day),
respectively. This means that, a daily enhancement in productivity of 12.55% and
17.93% for conventional distiller with water depth of 9 cm and modified distiller with
water depth of 9 cm over conventional distiller with water depth of 2 cm; respectively,
was obtained.
The accumulated productivities for conventional distiller with water depth of 3
cm, conventional distiller with water depth of 10 cm and modified distiller with water
depth of 10 cm were 1.49567 (lit/day), 1.340 (lit/day), and 0.885 (lit/day), respectively.
The CFD simulation for the conventional solar distiller will be presented. There
are two simulation modes, the first is a steady mode and the second is a transient mode.
The transient mode was used because it allows executing many calculations and leads
to a real simulation of the distiller.
A comparison between the experimental and simulated results of temperatures
and productivity has been made. On 14th July, for conventional distiller with 2 cm
water basin depth, the maximum experimental and simulated temperature for absorber
plate were found 71 and 75.4 C; respectively, with enhancement of 6.19 % and for
glass cover were 59 and 52.5 C with relative change of 11.02 %. Whereas.
