Abstract: |
The material presents methods for studying various nozzle configurations.The validation of the numerical studies was performed by comparison of the results of the jet reaction force A with a variety of absolute pressure values at the nozzle inlet, because the jet reaction force value affects the time and efficiency of the material processing. The higher the force A value, the higher is the air-abrasive mixture speed value and the more effective the nozzle is. |

Notes: |
To optimize the industrial nozzle UDC32-450 on a sand-air mixture, numerical studies were carried out in the ANSYS software package according to the developed methodology. 1. The inlet pressure was set (the outlet pressure was constant atmospheric).2. Under such conditions, the air flow rate m_air, kg/s, was determined. 3. In this case, the mixture consumption m_mixture = m_air + m_part. For the study, river sand with a diameter of 0.5 mm was used as an abrasive. 4. Two working environments were set: flued - air and particle - sand particles with a given diameter. For flued, we used the turbulence model sst, the Total Energy model, and for particles, we chose the mass flow rate of these particles. 5. At the inlet for flued, we set the pressure and temperature, and at the outlet - the pressure. The wall roughness was set to 3.2 μm. Sand parameters that were set during the modeling: D_part = 0.2-0.8 mm - diameters of grains of sand (particles), m_part = 0.03 kg/s - mass flow rate of sand (particles); air flow rate was set at m_air = 0.035 kg/s; outlet pressure was constant atmospheric. Dimensions and 3D model of the industrial flow part of the industrial nozzle UDC32-450 (critical diameter dkr = 6 mm): V1 = 45 mm; V5 = 30; V6 = 20 mm; V7 = 80 mm; H2 = 16 mm; H4 = 6 mm. |
