The paper presents a possible method for calculation of some parameters of an experimental setup for investigation of superfluid-helium (He II) film boiling in microgravity. The stationary process of He II film boiling on a cylindrical heater within the cavity inside a capillary-porous body is studied. The molecular-kinetic approach is applied to description of the transport phenomena on the He II-vapor interface. The results of calculation which illustrate the approach presented are given. The investigation suggests the superfluid-helium mass flow rate to be of an order of gram per minute during operation of the experimental setup.
