On the vortical structure in a plane impinging jet [PDF]

open access: yesJournal of Fluid Mechanics, 2001
The vortical structure of a plane impinging jet is considered. The jet was locked both in phase and laterally in space, and time series digital particle image velocimetry measurements were made both of the jet exiting the nozzle and as it impinged on a perpendicular wall.

On impinging near‐field granular jets [PDF]

open access: yesInternational Journal for Numerical Methods in Engineering, 2009
AbstractIn this work a multibody collision model, amenable to large‐scale computation, is developed to simulate a jet of near‐field grains impinging on a surface. This model is developed by computing momentum exchange for grain–grain and grain–surface interactions.

Combined Process‐ and Phase‐Field‐Simulation to Predict the Microstructure of Single‐Crystal Ni‐Based Superalloys

open access: yesAdvanced Engineering Materials, EarlyView.
A combined finite element and phase‐field approach predicts the evolution of microstructure during the directional solidification of Ni‐based superalloys. The model reveals how withdrawal rate, temperature gradient, and wall thickness control the dendrite spacing, highlighting the strong effect of surface regions in thin sections where dendrite growth ...
