A new empirical equation is proposed to calculate the pool boiling heat transfer coefficient according to the azimuth angle, inclination angle, included angle, and heat flux of the V-shaped tube array. For the development of the correlation, 1164 experimental values obtained from experiments conducted using two stainless steel tubes submerged in saturated water at atmospheric pressure and the least squares method were used. It was confirmed that the developed formula predicts the experimental value well within the range of ±10%.
