Investigation of distribution uniformity of distributor for biogas slurry application based on CFD analysis

A horizontal distributor for biogas slurry application was proposed to explore the distribution performance through CFD analysis and verified by field test. The rheological properties of were analyzed at first, key parameters obtained next simulation. effects modes, inlet direction, outlets number on velocity flow mass rate horizonal investigated simulations. Results indicated that a non-Newtonian fluid exhibited shear-thinning behavior. It can be well described power-law model. simulation results showed geometry rotor, especially block numbers main factor determining movement trajectory output. mode rotor 1 with two blocks reached lowest variable coefficient (4.49%), indicating higher degree uniformity. upward direction would obtain less dead zone, an even possess more uniform zone. test 1, 24 has been carried verify results, 13.06%, which slightly than (9.23%), but it still within range requirement (<15%). model findings this work are guiding significance study utilization technology equipment liquid residue.
