heal.abstract	A computer algorithm for the simulation of heat and mass transfer in humidification processes is based on a finite difference solution of the momentum, heat and mass transfer differential equations and of the continuity equation supplemented with the k epsilon turbulence model in the case of turbulent flow. Experimental validation of the procedure is made in the case of a counter current annular air-water two-phase flow in a circular vertical tube. Measurements have been made of the velocity and of the dry and wet bulb temperatures in various axial and radial positions within the tube. The parameters influencing the process are numerous including the water and air Reynolds numbers, water film thickness, water and air inlet temperatures, inlet humidity of the air and the corresponding inlet velocity profile. Comparison of the experimental values with the calculated ones show that the simulation method developed is reliable.	en
