چکیده انگلیسی
The research of transient heat transfer in a pulse process of the pulse reactor is not perfect at present, because the parameters change too rapidly in such process. The heat transfer between fuel rod surface and coolant is the key of the analysis. In this study, system and feedback theory is attempted to be applied in heat transfer analysis; a new concept-heat transfer coefficient delay is introduced. Two methods of analyzing kinetic characteristics: direct heat transfer calculation and model analysis are performed. A new idea-system module analysis with heat transfer coefficient delay is introduced into direct heat transfer calculation, which is solved by tool “Simulink”. This method is easier and more convenient than old. In model analysis, the multi-model method is adopted for obtaining the transfer functions. As a new original attempt, the multi-model simulation is also performed using visual operation by Simulink (not pure S-function). As a conclusion, the problem that cannot be solved by traditional analysis can be explained in this paper; and the analysis method and simulation technology recommended in this paper can effectively simplify the operation. The conclusion can be applied in correlative research.
