Thermal characteristics of slug flow in rectangular ducts.

Author(s) : MORINI G. L.

Type of article: Article

Summary

A rigorous solution is obtained for the temperature field and the Nusselt numbers in the fully developed thermal region of rectangular ducts, in which a uniform velocity profile occurs (slug flow). The thermal boundary conditions T (constant wall temperature peripherally as well as axially), H1 (constant axial wall heat flux with a constant peripheral wall temperature) and H2 (constant axial wall heat flux with uniform peripheral wall heat flux) are examined. The 2-D temperature distribution and the Nusselt numbers are calculated as functions of the aspect ratio. The results are presented in tables and graphs.
