 Mathematical modeling of the geometrical sizing and thermal performance of a Dish/Stirling system for power generationLuis Sebastian Mendoza Castellanos, Gaylord Enrique Carrillo Caballero, Vladimir Rafael Melian Cobas, Electo Eduardo Silva Lora and Arnaldo Martin Martinez Reyes Renewable Energy, 2017, vol. 107, issue C, 23-35 Abstract: This paper proposes a mathematical model for a solar Dish/Stirling system. Firstly, it is presented a methodology to calculate the appropriate angles and characterize the solar tracking control system for the city of Itajubá-MG/Brazil, in order to maximize the heat flow on the cavity of the receiver. Secondly, it was developed an algorithm for sizing and to determine the effects of opto-geometric parameters on the overall efficiency of the Dish/Stirling system. The model allows defining different configurations and geometric distances between the concentrator and the receiver, in order to obtain the desired heat in the receiver cavity. Finally, it is carried out a thermal balance for the evaluation of the maximum efficiency and overall efficiency of the system.
