عنوان انگلیسی Surrogate Model on the Extension Operation Range of an Isolated Centrifugal Fan
چکیده انگلیسی مقاله Isolated centrifugal fans are widely utilized in air conditioning system and their performance is closely related to the energy consumption of the system. The purpose of this work is to enlarge the fan operation range without reducing peak efficiency. An improved class and shape function method coupled the Kriging model is proposed to design fan airfoils and to optimize the efficiency and static pressure of the fan. Numerical simulation and experimental study show that both pressure coefficients in large and small flow rate are improved by this optimized fan, and the peak efficiency remains to be unchanged almost under design condition. Optimized pressure coefficient increased by 2.17% in design condition. Furthermore, operation range of the isolated centrifugal fan is enlarged via optimization design scheme and surrogate model. A better understanding of the physical mechanisms involved isolated centrifugal fan is further investigated.
