Such 2 types of models are simultaneously calibrated both by non-stationary operational data of temperature, humidity and pressure measurements received from the NBK over the course of months, and among themselves. This makes it possible to use a 1D model for long-term (months and years) analysis of the thermal and humid state of the NBK in separate 20 points of the NBK, as well as analysis of detailed distributions of temperature, humidity and pressure using a 3D CFD model with 1 million calculation cells in order to control of temperature and moisture irregularities in KP, a demonstration of which is given in the report Product Description popup.authors Liudmyla Asieieva Davydenko Borys V.
