质量传递模拟技术可以提供一种快速和廉价的方法来确定对流传热系数。一种方法是在研究对象的表面涂上一层薄薄的萘，然后观察升华到经过表面的气流中的速率。这种方法的成功取决于萘涂层的质量和厚度是否均匀。已开发出一种喷涂萘的技术，并在外表面和内表面都取得了一致可靠的结果。
Mass transfer analogue techniques can provide a quick and inexpensive method of determining convective heat transfer coefficients. One method involves coating the surfaces under investigation with a thin layer of naphthalene and observing the rate of sublimation into an airstream passing over the surfaces. The success of this method is dependent upon the naphthalene coating being of suitable quality and uniform thickness. A spraying technique for applying the naphthalene has been developed and has achieved consistently reliable results for both external and internal surfaces.
