An Experimental Study of Performance of Water Stirring Solar Still

Experimental Study on an Enhanced Performance Solar Water Heater

The paper presents preliminary results of an experimental study on solar water heater with full width and 75% twisted tapes as heat transfer enhancement device. The study shows that the thermal efficiency due the use of the twisted tape increases by 4.5-8%; higher for the 75% twisted tape. Keyword Solar water heater (collector), tube-in-fin, twisted tape, thermal efficiency, performance enhance...

An experimental investigation on the performance of a symmetric conical solar collector using SiO2/water nanofluid

One of the effective methods to improve the thermal efficiency of solar collectors is using nanofluids as the coolant. The present study experimentally investigated the effect of SiO2/water nanofluid with 1% mass fraction on the performance of a symmetric collector, i.e. conical solar collector. The conical solar collector with 1 m2 area and normal to the earth was tested in Ahvaz, a city in th...

Thermal performance enhancement of automobile radiator using water-CuO nanofluid: an experimental study

In the present paper, the effect of water-CuO nanofluid on the radiator heat transfer of an automobile, Peugeot 405 XU7 engine type is investigated experimentally. The experiments are carried out for the radiator water (water-ethylene glycol with a volume fraction of 80-20, respectively) as a base fluid and water-CuO nanofluid with the volume fraction of 0.5% and 1%. Sodium Dodecyl Sulfate (SDS...
