Usage: to simulate hydrodynamic processes in the array by equivalent materials. SUMMARY OF THE INVENTION: a housing 1 is provided with two mobile B (14) and two dead 5 (13) placed on the sides and bottom of the slab-A (12). At A (12) between the B (13) and B (14) is placed deformable block BL (2). BL (2) is entered into the screen E (18) and closed lid plate-K (16). During assembly in the central portion BL (2) is placed injectable torus (5) with a perforated tip
