Abstract
In power generation projects whose energy supply comes from solar source it also becomes necessary to evaluate other parameters that are as important as the solar radiation so that it can make the process more efficient. This work aims to analyze the properties of the working fluid (water) in a power generation system whose energy input is made by heating the fluid by a Concentrating Solar Power (CSP) system of the Linear Fresnel Reflector type (LFR). Namely, in the LFR system a number of inclined flat mirrors redirects the Direct Normal Irradiance (DNI) to tubes, where the working fluid flows, that is located in the focus of the set of these mirrors. The mass, momentum and energy conservation equations were solved based on the Finite Volume Method (FVM), whose discretization was done by the upwind method and the pressure-velocity coupling problem will be solved by the SIMPLER method. Based on this method of resolution it was possible to obtain a monitoring of water status variables, such as pressure, temperature and title. A comparison was made between the numerical results and the experimental results found in the literature and an average relative error of approximately 3%.
