薄膜萘传质模拟技术提供了一种在各种情况下比较强迫对流换热系数的快速和经济的方法。本文概述了该技术的进一步发展，使其能够直接和准确地预测绝对换热系数。在雷诺数为7·6×10 4&Re<；1·3×10 6的范围内，管内流动的换热系数与科尔本方程所给出的换热系数在±5%范围内吻合较好。
The thin-film naphthalene mass-transfer analogue technique has provided a rapid and economic method of comparing forced convection heat-transfer coefficients in a variety of situations. The present contribution outlines a further development of the technique to the stage that it is capable of predicting absolute heat-transfer coefficients directly and-accurately. Heat-transfer coefficients derived by analogy for flow through a tube agree with those given by the Colburn equation to within±5 per cent over a Reynolds number range 7· 6× 10 4< Re< 1· 3× 10 6. Tube entrance region heat-transfer measured by analogy is in good agreement with other investigations.
