... packed bed from 44.5 to 410 kg/(m2s). In the hydraulic model, with a view to improving the accuracy, the algebraic calculation of an average pressure is replaced with numerical integration over the bed height. In the gas-dynamic model, which allows analytical integration, refined constitutive relations are proposed. An analysis of the obtained results indicates that the gas-dynamic model provides a good description of experimental data, whereas the hydraulic model leads to a considerable error in ...
