The unglazed transpired solar collector is now an established solar air heater for heating outside air directly. Sample applications include pre-heating ventilation air and heating air for crop drying. The outside air in question is drawn straight fr

Experimental natural convection Nusselt numbers are reported for a cubical, air-filled cavity that has one pair of opposing faces isothermal at different temperatures, Th and Tc, the remaining faces having a linear variation from Tc to Th. Average Nu

A new natural convection ‘benchmark problem’ for validating CFD codes is defined. In the subject problem, a cubical air-filled cavity, tilted at 0, 45°, or 90°, has one pair of opposing faces at different temperatures, Th and Tc, respectively,

Solar heating systems often employ conduits to carry cool fluid to the collector array and to carry the heated fluid back to the storage tank. In systems in which these two conduits are bundled together in one cover (in what has come to be known as t

Natural convection heat exchangers are valuable devices in solar domestic hot water systems, but they are difficult to model. The output pressures and temperatures they develop are complex functions of the flow and temperatures that they are subjecte

A model for the average anisotropic sky radiance (or intensity) as a function of the position of the sun, the diffuse fraction k, and the atmospheric clearness index k1 are presented in this article. The complete range of sky conditions from clear to

Solar domestic hot water heating systems perform more efficiently if their storage tanks are perfectly thermally stratified. In real tanks, which do not perfectly stratify, the most important mechanism destroying stratification is plume entrainment.

Although optimum collector flow rates in solar water heating systems have been broadly established, the existence of such an optimum has not been demonstrated for systems having a heat exchanger between the collector fluid and the tank water to be he

Selective surface often degrade in the field. Their solar absorptivity αs and thermal emittance ϵ change with time in service by some amount, say Δαs and Δϵ, from their starting values. It is important to quantify the effect this degradation ha

An extensive data set of measurements of the shortwave sky radiance at Toronto, Canada, was compiled by the authors in 1984. A pyroelectric radiometer with a half-angle field of view of 5 degrees was used to make a total of more than 100,000 sky radi
