Summary

A solution is presented for the three-dimensional heat and mass transfer during evaporation of a circular meniscus of liquid ammonia, flowing parallel to a gaseous ammonia-hydrogen stream, as encountered in the evaporator of small neutral gas absorption refrigerators. The procedure developed is based on a finite difference solution of a set of differential equations expressing the three-dimensional transport of momentum, heat and mass. Expressions are also provided for the thermodynamic and transport properties of the real ammonia-hydrogen mixture. The results of the numerical solution include the fields of velocity, temperature, ammonia mass fraction, enthalpy and entropy.
