N2 - An experimental study of hydrodynamics and heat transfer under conditions of filtering of water and aqueous solution of glycerol through a porous insert in the channel was carried out. The values of the coefficient of hydraulic resistance and heat transfer for a chaotic backfill of balls with a diameter of 3.2 mm for filtering water and 47% glycerol solution have been determined. Three flow regimes were investigated: inertial, transient and turbulent. It has been found that, depending on the filtering mode through the porous insert, there are various laws of heat transfer. Comparison of the obtained results on heat transfer in ball fillings with the available literature data has been carried out. The obtained experimental data are in good agreement with the data of numerical calculations. For the thermal stabilization section at high values of the Reynolds number they are in good agreement with the data obtained by filtering air through a porous medium.
