Abstract

Abstract

The pressure pulse filter and Smagorinsky subgrid stress model of the LES（Large Eddy Simulation） are introduced.The fluid field in the annular plenum between the pressure vessel and the core barrel of the Qingshan II phase model test are simulated,and the distribution of the total pressure in the space and time are obtained.The results show that the PSD（Power Spectrum Density） of LES from the calculation and the test keeps the same quantity order.Thus,the pressure of LES can be a load to stimulate the barrel vibration.
