Alekseev, F. Kozlov, A. Sorokin, E. Varseev, V. Kumaev, A. Kondrat'ev] The design of a cold trap is optimized in order to maximize the capacity in terms of impurities. The main criterion of optimization is uniformity of the distribution of impurity deposits along the length of the trap. The modified OpenFOAM code was used to solve the complex thermohydraulic and mass transfer problem. The problem was modeled in a stationary formulation by solving the Reynolds average Navier-Stokes equations (RANS) by the SIMPLE method. The calculations showed that OpenFOAM makes it possible to calculate the heat exchange and mass transfer of impurities in the trap cavity. The MASKA-LM code was used in the calculations in order to take account of changes in the geometry of the computational region by deposits on solid surfaces. The proposed computational method makes it possible to evaluate the impurity capacity of a cold trap and the time to exhaustion of its service life.
