ABSTRACT

This paper gives similarity transformations for laminar filmwise condensation on a vertical flat plate with variable temperatures Tw = Tsat − G(x) and finds analytical solutions for arbitrary Prandtl numbers and condensation rates. The work contrasts with Sparrow and Gregg's assertion that wall temperature variation does not permit similarity solutions. Based on the similarity solutions, some useful formulas are obtained, including significant correlations for varying Prandtl numbers. Results are compared with the available experimental data.
