| Abstract: | Application of MATLAB in processing the comprehensive characteristic curves of hydraulic turbine is discussed, in this paper. First the image inputted into computer by digital instrument is received and the data sampled are saved in MATLAB, then interpolation and restoration based on these data are performed by programming in MATLAB, finally the comprehensive characteristic curves of hydraulic turbine are drawn according to the data transformed from that of the model hydraulic turbine in MATLAB. It is shown that the efficiency is im, proved in applying MATLAB to process the comprehensive characteristic curves of hydraulic turbine and MATLAB promises greatly in hydraulic engineering design. |
