Abstract: Venting and evaporative cooling are modeled as possible techniques for protecting polymer absorbers in single-glazed, flat-plate solar collectors from exceeding the material temperature limit during ...

Abstract: The feasibility of reducing the cost of solar water heating systems by using polymer heat exchangers is illustrated by comparing thermal performance and cost of heat exchangers made of nylon, ...

Abstract: This paper summarizes current research aimed at using polymer materials for glazing and heat exchanger components in solar water heating systems. Functional requirements, relevant polymer properties ...

Abstract: The use of a heat exchanger in solar water heating systems reduces the overall system efficiency. In this paper, we derive a simple "penalty factor" that gives the fractional reduction ...

Abstract: All materials experience a force when placed in a region of magnetic field and field gradient. The magnitude of this force depends on the magnetic susceptibility of the material and this ...
