This study focuses on the mathematical modelling of solar concentrator
type “parabolic trough plan” a thermal balance was established respectively on the
coolant on the absorber tube and the glass envelope, the system of equations
obtained is solved by the method of finite differences, results are obtained for a typical
day, the variation of the temperature of the coolant, the absorber tube and the glass
envelope and the evolution of the power of the heat loss and efficiency of the
concentrator
