An Experimental Study Of Molten Microdroplet Surface Deposition And Solidification: Transient Behavior And Wetting Angle Dynamics, Daniel Attinger, Z. Zhao, D. Poulikakos Apr 2000

An Experimental Study Of Molten Microdroplet Surface Deposition And Solidification: Transient Behavior And Wetting Angle Dynamics, Daniel Attinger, Z. Zhao, D. Poulikakos

Daniel Attinger

The basic problem of the impact and solidification of molten droplets on a substrate is of central importance to a host of processes. An important and novel such process in the area of micromanufacturing is solder jetting where microscopic solder droplets are dispensed for the attachment of microelectronic components. Despite the recent appearance of a few numerical studies focusing on the complex transient aspects of this process, no analogous experimental results have been reported to date to the best of our knowledge. Such a study is reported in this paper. Eutectic solder (63Sn37Pb) was melted to a preset superheat and …

Thermodynamic Analysis Of Thermomechanical Coupling Incouette Flow, Yasar Demirel Dec 1999

Thermodynamic Analysis Of Thermomechanical Coupling Incouette Flow, Yasar Demirel

YASAR DEMIREL

Couette ¯ow provides the simplest model for the analysis of heat transfer for ¯ow between parallel plates and between two coaxial cylinders. Design of such devices with the consideration of the thermo- mechanical coupling of viscous heat generation and Couette ¯ow is important since they are used in lubri- cation, polymer and food processing, and viscometry.
