Численное исследование инвариантности некоторых моделей многокомпонентных сред

Численное исследование инвариантности некоторых моделей многокомпонентных сред

Abstract

Проведен сравнительный анализ инвариантности относительно преобразования Галилея математической модели «замороженной» газовзвеси и модели двухскоростной гетерогенной среды. Показано, что в случае «замороженной» газовзвеси неинвариантность уравнений этой модели проявляется в росте энтропии, что ведет к нарушению второго закона термодинамики. В случае двухскоростной среды неинвариантность проявляется достаточно слабо и практически не влияет на результаты расчетов.
