An experimental study has been conducted to investigate the turbulent mixing and heating caused by a (superheated) steam jet injected into a turbulent cross-flow of water in a square channel. The velocity field in the mid plane of the channel has been measured by means of particle image velocimetry for several different values of the ratio of the momentum(More)
In this paper we study the behavior of an inkjet-printed droplet of a solute dissolved in a solvent on a solid horizontal surface by numerical simulation. An extended model for drying of a droplet and the final distribution of the solute on an impermeable substrate is proposed. The model extends the work by Deegan, Fischer and Kuerten by taking into account(More)
Three-dimensional particle tracking velocimetry (3D-PTV) has been applied to particle-laden pipe flow at Reynolds number 10,300, based on the bulk velocity and the pipe diameter. The volume fraction of the inertial particles was equal to 1.4 Â 10 À5. Lagrangian velocity and acceleration statistics were determined both for tracers and for inertial particles(More)
Three-dimensional particle tracking velocimetry (3D-PTV) is applied to particle-laden pipe flows at Reynolds number 10,300, based on the bulk velocity and the pipe diameter. The effects of flow direction (upward or downward) and mean concentration (in the range 0.5 Â 10 À5 –3.2 Â 10 À5) on the production of turbulence are assessed for inertial particles(More)
