TL;DR: In this article, the effects of the dispersed phase content and the viscosity of the disperse and continuous phases in different nozzles are compared with one another, and the results can be explained on the basis of the mechanisms of disruption.
Abstract: High-pressure homogenizers are frequently employed for the homogenization of low-viscosity emulsions containing a proportion of disperse phase which is not too high. High-pressure homogenizers essentially consist of a high-pressure pump and a homogenizing nozzle. The design of the homogenizing nozzle influences the flow of the emulsion in the nozzle itself and hence the results of droplet disruption. It is shown which mechanism in frequently used homogenizing nozzles is usually responsible for disruption. Experimental results reveal the effects of the dispersed phase content and the viscosity of the disperse and continuous phases in different nozzles. The results can be explained on the basis of the mechanisms of disruption. Finally, the homogenizing nozzles presented are directly compared with one another.

TL;DR: In this article, a single- nozzle spray cooling heat transfer mechanism with varying amounts of dissolved gas was investigated using two powerful techniques: time and space resolved heat transfer distributions produced by a single nozzle were measured using an array of individually controlled microheaters, while visualization and measurements of the liquid-solid contact area and the three phase contact line length were made using a total internal reflectance technique.

TL;DR: In this article, a wall jet electrode was presented, in which a jet of solution issued from a circular nozzle was allowed to impinge normally on a disk electrode. And the theoretical predictions for the dependence of the limiting diffusion current upon various experimental variables, i.e., the bulk concentration of depolarizer, the volume flow rate, the radius of the disk electrode, the diameter of the nozzle, etc., were verified experimentally.

TL;DR: In this article, the authors propose to obtain a stable dot reduced in irregularity by partitioning the nozzle communicating with an ink tank into a control nozzle and an emitting nozzle by a heat insulating material and integrating the substrates of both nozzles into the same shape.
Abstract: PURPOSE:To obtain a stable dot reduced in irregularity by partitioning the nozzle communicating with an ink tank into a control nozzle and an emitting nozzle by a heat insulating material and integrating the substrates of both nozzles to process both nozzles into the same shape and fixing a heating element to the inner periphery of the control nozzle. CONSTITUTION:Conductive layers 14 are formed on both surfaces of a control nozzle substrate 10 and an emitting nozzle substrate 11 is bonded to the single surface of the substrate 10 through a heat insulating material 8. Next, V-grooves constituting nozzle orifices are formed in the end surfaces of the substrates 10,11 and a heating element 4 is formed in the V-groove of the control nozzle substrate 10. Subsequently, the V-grooves of both substrates are abutted to be bonded and the conductive layer 14 exposed to the surface of the substrate 10 is removed so as to leave a wiring pattern 15. When the heating element 4 is operated by supplying a current across the conductive layers and the wiring pattern 15 to generate heat, solid ink 9s is melted at the contact surface with the heating element 4 to be extruded to an emitting nozzle 3 and the molten ink 9r in the emitting nozzle 3 is emitted. The solid ink 9s advancing into the emitting nozzle 3 becomes the molten ink 9r by the heat of the substrate 11 and this molten ink 9r is emitted by next emitting operation.
