In Pb Bi loop, the turbulent buffeting phenomenon of lead bismuth fluid in heat exchanger, may cause fatigue damage of heat transfer tube. Through the establishment of Pb-Bi loop heat exchanger model, invent a program for calculation, we can get the turbulent buffeting characteristics. The results show that: As the increases of heat exchange tube cross number, the buffeting coefficients pipeline is greater, the probability of occurrence of turbulent buffeting phenomenon is more low; The greater lead bismuth flow velocity is, the more prone to turbulent buffeting phenomenon. With vertical heat tube center distance increases, the buffeting coefficients decreased first and then increased, when the buffeting coefficients reached the minimum value, the turbulent buffeting phenomenon is most intense; As the horizontal heat pipe center distance is bigger, turbulent buffeting phenomenon is becoming less clear.
