摘要：

The complex interaction among the thermodynamic and transport characteristics of an evaporator used as a vapor delivery system is explored in a steady-state model. An example is presented which shows how one may calculate the operating temperature required to yield a specified delivery rate, as a function of vapor pressure of the liquid, and the conductance of the flow path downstream of the evaporator. Under some conditions, liquid droplets may be entrained with the vapor flow. A model is presented for the distance downstream of the evaporator required for evaporation of these droplets.
