The significance of solar energy has recently diverted the attention of researchers; this is due to the experimental or the numerical analyises of solar energy and lack of fractional analytic approaches. This manuscript is communicated to model the problem of the enhancement of heat transfer...

This article examines different passive and active heating systems for swimming pools. The passive systems introduced in this article are:

The results of five-year study of the heat consumption in a single-storey terraced low-energy residence are presented. The house is part of a forty building Warsaw housing estate Wilanow–Zawady.

Two types of ICS solar water heaters designed, constructed and tested. The systems consist of two cylindrical storage tanks, which are connected in series and are horizontally incorporated in a stationary asymmetric CPC type mirror. The efficient operation of the system is due to the thermal...

The purpose of this work is to examine specific features of thermal and photovoltaic solar systems and their contribution to the sustainable tourism development of Mediterranean islands. In doing so, the best practices are studied and the factors which influence the transfer of these practices...

Most solar collectors commonly used are of the flat-plate type. In the present work, a novel type of solar collector, namely, spherical collector, is proposed. It consists of a stationary spherical body with a cover and an absorbing surface. The receiving hemisphere, normal to the incident beam...

Heat losses in solar energy collectors are associated with thermodynamic irreversibility, which causes entropy generation. These losses can be reduced through EGM (entropy generation minimization) techniques. Using computational fluid dynamics, entropy generation associated with viscous...

The effect of the heat loss from the piping system of a solar collector field of a large size is measured and the effect of this loss on the effective collector efficiency is evaluated. The data are used to develop a model that can be used to evaluate the effect of piping loss on collector...
