Numerical investigation of wall conduction effects on laminar mixed convection in inclined circular tubes.

Author(s) : LAOUADI A., GALANIS N., NGUYEN C. T.

Summary

The wall conduction effects on a fully developed ascending laminar flow involving mixed convection of air inside an inclined tube subject to a uniform heat flux on its outer surface have been numerically investigated. These effects have been found to be significant on both the hydrodynamic and thermal fields, especially for horizontal tubes. In general, an increase of the tube wall thermal conductivity appreciably reduces the temperature stratification inside the fluid, and intensifies the secondary flow. Detailed results are given.
