Modelling and Experimental Validation of an Optical Fiber for Solar Devices

摘要

In this paper it has been presented a numerical model of an optical fiber used in the solar applications. We discussed the overall thermo-mechanical design and the behaviour of the system, composed of the fiber and its holder. Starting from the geometrical choices and from the analyses of the selected fiber, the response of the device is computed via numerical simulations. The geometry shape and characteristics of the optical components are selected among commercially available optical fibers while the shaping of the aluminium component used as clamper is chosen in order to easily set up the laboratory measures. The calculated model has been validated by means of an experimental setup. The results are well suitable to design a device for the transmission of concentrated solar energy via an optical fiber.
