Experimental Study on the Biological Blockage Response of the Network Which Protects the Cold Source of Nuclear Power Plant
摘要
Abstract
This study analyzes the structural stress characteristics of a debris filter net under various marine biological blockage conditions.Firstly,the velocity of currents near water intake is measured based on shipborne ADCP,using the Karman-Prandtl model and polynomial interpolation methods were employed to reconstruct the vertical velocity profiles from stratified observation data.Subsequently,t a finite element(FE)model of the filter net was developed,and its mechanical response was calculated under different blockage scenarios.The results indicate that the three-order polynomial fitting is more suitable for the observation sea area than the Karman-Prandtl model.When the blocking height is less than 7 m,the minimum of the force is small,which is the safety zone of the rope;when the height of blockage is greater than 7 m,the maximum of the force shows a significant linear increase with the elevation increasing.Consequently,the section of the net above 7 m is identified as a high-risk area,where the structural risk escalates gradually with increasing blockage height.关键词
