This correlation was historical the first physical permeability model, based on the fluid flow in porous media with simplified structure consisted of a bunch of independent capillaries with various diameters.

Later on it's been upgraded to percolation through inter-grain porous space which specifies the Модель Козени-Кармана является исторически первой и наиболее популярной физической моделью проницаемости, основанной на гидродинамических уравнениях флюида в поровом коллекторе с упрощенной структурой независимых друг от друга капилляров разной длины, диаметра и формы и представляет собой линейную зависимость индекса качества пород от нормализованной пористости
