The effect of the azimuth angle and the heat flux of the lower tube on the heat transfer of the upper tube of the V-type stainless steel tube arrangement submerged in water under atmospheric pressure is experimentally investigated. The increase in azimuth and lower tube heat flux improves the heat transfer of the upper tube, and this trend is clearly observed when the upper tube heat flux is less than  An empirical formula that can evaluate the bundle effect is newly developed using the values obtained from the experiment, and the correlation accurately predicts the experimental value within ±5%.
