Evaluation of liquid non-freezing conditions in large vessels with local heating scheme using the Ansys Fluent software
Keywords:
natural convection in big volume, optimizing CFD-model, cold bridges, LES-model, vessels heatingAbstract
A computer simulation of an operating water storage tank, RGSn-100, with mortise electric heating elements, for specified conditions was carried out using Finite Element Analysis software ANSYS 2021 R1. The ANSYS Fluent software package was used to solve a three-dimensional numerical simulation of natural convective flows of a viscous incompressible fluid and heat exchange processes with local heating and cooling in a large volume. Several approaches were used to select optimal methods describing convective flows in a large volume most accurately with limited resources. The influence of the heating scheme and cold bridges on the heating efficiency and the risk of freezing is considered. The article provides examples of calculations and gives specific instructions for solving problems of natural convection in large volumes using software tools - models, functions, acceptable simplifications.
