An Approach to Employing Speed Dependences of the Pressure Loss in Filter-Matrixes to Diagnose the Transitional Regime of the Flow
The paper analyses the data on pressure differential p in a layer of balls loading (of the matrix), the statistics varying with the speed of filtration and the balls diameter. Employing the solid approach to generalization, we obtained explicit reference to critical (transition) value of the Reynolds number (Re=60-80). Alternatively to the recognized universal expression for p, the article provides individual expressions of p fair for laminar and post-laminar flow regimes respectively. The paper features a comparative analysis of different options for considering the filtering media porosity impact.
