Abstract: A study is made of heat transfer rates in channels with complex shape. A method is discussed for investigating the statistical characteristics of temperature pulsations of a sodium–potassium alloy in a cell densely packed with rods. Data are presented on the intensity of pulsations, amplitude distribution, asymmetry, excess, autocorrelation function, frequency spectra, and time scales of turbulence for $1/6$ of the symmetric part of the channel cross section.
