The paper contains the computer modeling results of the hydrodynamics of the thermal agent movement through a stationary layer of dried barley brewer’s spent grain. To carry out the modeling, the characteristics of the porous zone were previously determined, including the layer porosity ε of the studied material, the values of the viscous 1/α and inertial C2 resistance coefficients. Simulation was done in the ANSYS Fluent 2022 R2 software package using the k-ω SST turbulence model. The study was carried out for the researched heights of the dried brewer's spent grain layer in the range of H = 80÷120 mm at the thermal agent flow velocities w0 = 0.83÷1.78 m/s. Based on the experimental data of the layer’s hydraulic resistance, the average modeling error for all experimental points was calculated to be 6.85 %.
