Multivariable modeling of an innovative hybrid solar-gas dryer
[EN] The main goal of this paper, is to propose a multivariable control model (MM) issued from CFD study of an innovative hybrid solar-gas dryer to simulate the drying chamber temperature in three modes of operation: Solar mode, Gas mode and hybrid mode. There is an indirect heating of drying air instead of direct heating inside the drying chamber. The air temperature obtained by CFD is still closed to one obtained by multivariable model (MM) with an RMSE under 2.31. the proposed multivariable model leads to a quick output parameters estimation related to each clilmate conditions and so, to an easy control of a hybrid solar dryer.This work was supported by the research institute for solar energy and new energies (IRESEN) as part of the project SSH and all of the authors are grateful to the IRESEN institute for its cooperation.Zoukit, A.; Elferouali, H.; Salhi, I.; Doubabi, S.; Abdenouri, N.
