| Abstract: | This paper tries to answer two questions. One is how to put the comprehensive character curves of Francis turbines (CCCFT) into the memory of a digital computer, the other is how to use numerical method to approximate these curves and interpolate among them. The method presented here is only the result of this effort, it has been used in several model turbines. The numerical experiment found that this method with clear physical meaning is simple, convenient and available. |
