| Abstract: | A method in proposed for correlating heat transfer coefficient in spiral-fluted tubes upon analysis of the distribution of heat transfer resistance. A correlation for turbulent single-phase flow is thus obtained, Valid for both single-and multiple-start spiral-fluted tubles, are a wide range of Prandtl number (Pr = 0.7 to 35). |
