Abstract
AbstractThe object of this study has been the measurement of concentration profiles of water vapor in a wetted‐wall column with fully developed turbulent pipe flow of air for several positions downstream of the inlet. The air Reynolds number was 25,000. The mathematical formulation of this problem involves the Navier‐Stokes equations and the mass transfer equation with a boundary condition of constant concentration at the wall. No attempt has been made toward an analytical solution of this problem, as the exact solution of the turbulence problem has not been developed. Instead, values of the mass and momentum transfer correlation, urh, and urux, have been computed as a function of the radius. The eddy diffusivity for momentum and mass and the local mass transfer rates are shown for engineering purposes.
