Численное моделирование затекания токсичного газа в помещение при аварии на промплощадке химически опасного объекта

Численное моделирование затекания токсичного газа в помещение при аварии на промплощадке химически опасного объекта

Abstract

Разработана трехмерная численная модель расчета процесса распространения токсичного газа на промплощадке и затекания токсичного газа в помещение при аварийном выбросе на предприятии. Модель основывается на численном интегрировании уравнения конвективно-диффузионного переноса примеси и на модели невязкой несжимаемой жидкости. Приводятся результаты вычислительного эксперимента.

The 3D numerical model to simulate the toxic gas dispersion at an industrial site and inflow of toxic gas into the industrial room after an accident ejection was developed. The model is based on the K -gradient transport model and equation of potential flow. The results of numerical experiment are presented.
