Mathematical simulation of mass transfer in the vertical settler МАТЕМАТИЧЕСКОЕ МОДЕЛИРОВАНИЕ ПРОЦЕССА МАССОПЕРЕНОСА В ВЕРТИКАЛЬНОМ ОТСТОЙНИКЕ
Mathematical models of secondary settlers have been intensively developed in the past several years. The challenge is to develop CFD models capable of taking account of the geometrical shape of the settler, the most important physical processes, and to perform calculations in the timely manner. The task of the authors was to develop a 2D numerical model designated for the research into the transfer of waste waters inside vertical settlers, for the model to take account of the geometrical shape and structural features of the settler. The authors employed finite difference schemes as the basic methods of research. As a result, a new 2D CFD model was developed. The novel model may be used to perform CFD studies of vertical settlers. This model takes account of the geometrical shape of the settler, the central pipe inside it, and other peculiarities. The CFD model and code developed by the authors constitute a solution to multi-parametric problems of the vertical settler design. Computer time taken by this model is equal to the one of a 1D model.
Рассмотрено построение численной модели массопереноса в вертикальном отстойнике. Моделирование осуществлено на основе двухмерного уравнения переноса примеси и модели потенциального течения. Для численного интегрирования применены неявные разностные схемы. Приведены результаты вычислительного эксперимента.
