Fast, Accurate Spray Breakup and Droplet Distribution in Multiphase Flows

Spray nozzle designers need to simulate detailed breakup mechanisms, and accurately predict droplet-size distributions and spray characteristics to optimize product performance. In spray nozzles, injectors and atomizers, liquid continuously disperses, eventually forming tiny droplets. The size distribution of the final droplets controls the evaporation and, in case of combustion systems, the homogeneity of the air–fuel mixture. Previously it was computationally impractical to calculate droplet size distribution using conventional methods. New functionality in ANSYS Fluent has reduced the computational effort significantly. Fluent uses the volume of fluid method to directly track the interface instabilities and surface tension effects that give rise to ligament and droplet formation. Then, the faster, more computationally efficient Lagrangian framework takes over to track the droplets.

Dynamic Mesh Fully Captures Pipe Degradation due to Erosion

Engineers seeking to maximize uptime and optimize preventive maintenance programs need to reliably predict the location and extent of erosion in pipelines that are carrying particle laden flows. Previously, static meshes could not account for structural changes in the pipe caused by erosion and its subsequent impact on fluid flow, reducing prediction accuracy. New technologies in Fluent automatically couple structural changes due to erosion with a dynamic mesh so that the simulation more fully captures the degradation arising from erosion.

Fluid-Structural Interaction: Accurately Account for Leakage Flows through Narrow Gaps caused by Structural Deformation

Automotive engineers seeking to reduce emissions need to minimize leakage of engine oil into fuel through fuel pumps. High operating pressures in modern designs can deform materials to widen the gaps between the plunger and cylinder walls and cause unexpected oil leakages. Until now, fluid–structure interactions in small gaps presented difficult challenges, making accurate simulations impractical. New technology in Fluent automatically inserts high quality mesh into the new deformations identified by coupling with ANSYS Mechanical. The resulting simulations provide highly accurate oil leakage flow rates that account for the structural deformations and can be used to optimize pump performance.
