Distribution of liquid velocity in the experimental model of a fuel assembly with a spacer grid

Distribution of liquid velocity and its pulsations were measured in the space between fuel elements of the 7-rod experimental model of the fuel assembly of nuclear power plants at Reynolds numbers of 8000, 16000, and 24000. The influence of the spacer grid on distribution of the axial component of l...

Description
Summary:Distribution of liquid velocity and its pulsations were measured in the space between fuel elements of the 7-rod experimental model of the fuel assembly of nuclear power plants at Reynolds numbers of 8000, 16000, and 24000. The influence of the spacer grid on distribution of the axial component of liquid velocity was determined. It is shown that the relative values of liquid velocity and its pulsations do not depend on the Reynolds number and they are determined by the distance from the spacer grid.
