A Numerical Study of High Moisture Flue Gas in Tube Banks

Abstract

In this article, a two-dimensional incompressible flow of high moisture flue gas in tube banks has been numerically simulated. The flue gas released both sensible and latent heat, and was treated as a combined heat and mass transfer problem. The finite-volume method was used to solve the Navier-Stokes equations, energy conservation equation, and species conservation equation. A simplified model was adopted and modified to account for the condensation phenomena in the flue gas. The influences of number of tube rows, gas velocity, vapor concentration, wall temperature, and tube diameter on heat and mass transfer characteristics were studied. The results analyses were presented by various criterions.
