Abstract

Concentrated solar power is a renewable resource exploitation area and involves a number of methods to capture and convert sunlight into electricity. One of the technical possibilities to achieve this consists in using parabolic surfaces to concentrate the solar energy onto one single spot. Usually, the energy captured by this method is transported by way of a thermal agent, a liquid substance in most cases. The purpose of this paper is to test the efficacy of using a solid substance to perform the heat transfer from the focal point on the parabolic surface to the opposite end where a Stirling engine will absorb the transferred energy. This efficacy was quantified through a specific coefficient that indicates the optimum length for the heat transfer.
研究聚光太阳能发电系统中通过固体物质传导热能的可能性
聚光太阳能是一个可再生资源开发领域,涉及许多方法来捕获和转换太阳光转化为电能。实现这一目标的技术可能性之一是使用抛物面将太阳能集中到一个点上。通常,通过这种方法捕获的能量通过热剂的方式传输,在大多数情况下是液体物质。本文的目的是测试使用固体物质从抛物面上的焦点到斯特林发动机将吸收传递能量的另一端进行热量传递的有效性。这种功效通过一个特定的系数来量化,该系数表明了传热的最佳长度。
