摘要：
The effects of working fluids on temperature fluctuation phenomena have been studied, with special reference to similarity rules for the thermal striping phenomena in LMFBRs. Temperature measurements were made in non-isothermal coaxial jets using sodium, water and air as working fluids. These experimental results indicated the dependence of the characteristics of average and root-mean-square values for the temperature and peak-to-peak amplitudes and periods of temperature wave-form signals on Reynolds and Peclet numbers. It may be concluded that the characteristics of temperature fluctuation due to turbulent mixing in LMFBRs can be evaluated from the results of model tests using water and/or air if the Reynolds and Peclet numbers are sufficiently large. © 1990.
