Purpose of research - creation of mathematical model heat and masstransfer in low-temperature thermal pipes being one from perspective base elements of systems of maintenance of a thermal mode of space vehicles.

The set of equations circumscribing heat and masstransfer, actuates equations of preservation of weight, impulse both energy for liquid and steam phases of a cooling agent, and also heat conduction equation for a body of a pipe. The problem is decided by a finite difference method, difference analogues of equations - method of fractional steps. The hydrodynamic and thermal problems of steam phases of a cooling agent, were decided within the framework of model of a laminar boundary layer. The solutions, obtained in an outcome, of a problem of distribution of hydrodynamic and thermodynamic parameters correspond to known experimental data.
