Justifying the experimental method for determining the parameters of liquid infiltration in bulk material

The object of this study is the process impregnation liquid into bulk material, in particular, soil. Determining parameters a relevant task when assessing consequences an emergency spill hazardous liquid. Infiltration soil leads to pollution water resources. However, greatest danger ignition combustible Based on Green-Ampt model, mathematical description material was built. It system two ordinary differential equations first order, one which describes reduction thickness layer surface, and other dynamics depth. solution derived form time dependence depth impregnation. An experimental conducted example crude oil sand. To end, sand poured vertical measuring glass cylinder. After that, video recording carried out. By processing recording, corresponding were determined. results show that relationship between surface linear nature: relative deviation approximation from data does not exceed 3.5. expanding logarithmic function contained Taylor series, polynomial established. determine coefficients based data, least squares method used. In case, error after minute spilling 10 %. proposed could be used account for seepage model spreading ground burning flammable
