𝗗𝗶𝗿𝗲𝗰𝘁 𝗻𝘂𝗺𝗲𝗿𝗶𝗰𝗮𝗹 𝘀𝗶𝗺𝘂𝗹𝗮𝘁𝗶𝗼𝗻 𝗼𝗳 𝘁𝘄𝗶𝗻-𝗳𝗹𝘂𝗶𝗱 𝗮𝘁𝗼𝗺𝗶𝘇𝗮𝘁𝗶𝗼𝗻! From the abstract: "Three-dimensional direct numerical simulations of a twin-fluid atomizer in the annular regime are performed to study the multiphase instabilities, shock waves, and the onset of atomization. The injection involves a sonic air jet surrounded by an annular layer of liquid. The expansion of the sonic jet results in shock wave formations, Rayleigh–Taylor, and Kelvin-Helmholtz instabilities that cause the annular liquid sheet disintegration into ligaments and droplets. Three simulations at varying driving pressure; 0.55 MPa, 0.8 MPa, and 1.2 MPa, showed an interesting change in the dimensions of the Mach disk shock-wave as well as the deformation of the liquid sheet."

Using Discrete Element Method (DEM) simulations, we can gain valuable insights into the behavior of particles on vibrating screens. Recently, we ran a three-particle simulation to understand granular flow, collision dynamics, and screen interactions. These detailed simulations help us optimize screen design, improve efficiency, and predict maintenance needs—leading to more reliable and effective mineral processing equipment. #MineralProcessing #DEM #VibratingScreens #Simulation #Innovation #Engineering
