Solar water heating (SWH) systems have a widespread usage and applications in both
domestic and industrial sectors. According to Renewable Energy Policy Network data …

This work is a three-dimensional numerical study of a U-shaped evacuated tube solar
collector employing different types of oxide nanofluids including water–Al 2 O 3, water–CuO …

In this paper, based on the energy balance for the glass evacuated tube solar collector with
U-tube, the thermal performance of the individual glass evacuated tube solar collector is …

The filled-type evacuated tube with U-tube, in which the filled layer is used to transfer energy
absorbed by the working fluid flowing in the U-tube, is proposed to eliminate the influence of …

Thermal performance of a novel minichannel-based solar collector is investigated
numerically. The particular collector consists of a U-shaped flat-tube absorber with a …

In the solar thermal field, the U-pipe evacuated tube collector has been widely used to
provide hot water for domestic usage and space heating, or integrated with concentrating …

Performance of a simple one-ended, evacuated tube solar collector was experimentally
studied as a compact unit-cell for air heater at low steady flow rates. The investigated unit …

The heat flux in the focal region of a compound parabolic collector (CPC) and the receiver's
surface is varying and ununiform, and its effective absorption is one of the challenging tasks …

In this study two new simple methods are extended for thermal performance evaluation of
minichannel collectors. The classical fin analysis method is employed for minichannel …

Abstract In the United States, water heaters are the second highest source of energy usage
in households. A wide variety of water heater configurations are available in the market …
