Abstract
The improved mathematical model and its program implementation are presented. It describes the gasdynamic solution of dry gas seals for the rotors of centrifugal compressors. The distinctive feature of proposed mathematical model is that it takes into account the influence of gas temperature on the resulting distribution of gas pressure in the gap between seal rings. The developed software package GasDin contains modules of gasdynamic solution taking into account the temperature distribution in the gas layer and at a constant temperature. Also it carries out the whole process of solution of dry gas seal, including the solution of gasdynamic, heat transfer and thermoelasticity problems according to a specially developed iterative algorithm. The created algorithm and developed software package GasDin have been tested on real designs of dry gas seals and can be used for modeling and servicing of dry gas seals.
