Abstract:
To the flow and heat transfer characteristics in near wall region for jet flow with different injection angle in the reactor coolant system,based on the test results,the flow characteristics and mixing function and non-dimensional heat transfer coefficient in different regions of T junction components with 45
0 and 90
0 injection angle were compared and analyzed at the velocity ratio range from 0 to 2.The research results indicated that the effect of the injection angle on the change trend of the mixing function and non-dimensional heat transfer coefficient is small,and the key parameter determining the change trend is still the velocity ratio:The effect of the injection angle is only on the values of the mixing function and non-dimensional heat transfer coefficient.
