AN EXPERIMENTAL STUDY OF HEAT AND MASS TRANSFER FOR ABSORPTION OF LiBr SOLUTION FILM FALLING OVER HORIZONTAL CIRCULAR TUBES

On the range of nondimensional spray fluxes of LiBr solution 10≤Γ/μ≤50 and of initial concentrations on LiBr solution 50% ≤ 100%−ξ ≤60%, LiBr solution film absorbing water vapour in an experimental absorber has been experimentally investigated. The obtained coefficients of heat and mass transfer of LiBr solution film were expressed in the nondimensional forms, Nu = f(P,Pr)and SH = F(R, Sc),respectively.
