Ductile and Compacted Graphite Iron Casting Skin - Evaluation, Effect on Fatigue Strength and Elimination
… the original casting surface (a.k.a. casting skin), the actual performance of the part could be significantly different from that of the machined specimens. Recent studies have shown the negative effect of the casting skin, but little quantification of its effect on mechanical properties is …

Characterization of Black Liquor Sprays for Application to Entrained-Flow Processes
… relevant temperatures on the droplet formation process, relative to room-temperature conditions. It was found that high solids black liquor forms long, thin ligaments rather than droplets. In high-temperature surroundings the size of these ligaments increases, which from a comparison …

Mechanisms of drying of skin forming materials
… out on single droplets of different types of skin-forming materials, namely, custard, gelatin, skim milk and fructose at air temperatures ranging from 19°C to 198°C. Dried crusts were recovered and examined by Scanning Electron Microscopy. Skin-forming materials were classified into three …

The isolation and study of rheological and mass transfer parameters in the spinning of advanced hollow fibre membranes for gas separation
… conditions i. e. phase inversion on membrane formation. This study adopts a rheological perspective and closely considers the mass transfer and skin formation processes in the dry gap. In the first phase of work two spinning programmes were carried out; one where extrusion shear was varied …

Wetting and Penetration Behavior of Resin/Wood Interfaces
… All contact angles were unfavorable due to a skin formation. The Lucas-Washburn equation did not predict any penetration; however, penetration was observed with all systems. The findings suggest that the system was too complex for the Lucas-Washburn equation to be able to predict accurately.

The Single drop drying of heat-sensitive materials
… most of its activity. The performance of various skin-forming encapsulants, viz. rice and wheat starch, dextrin, coffee, skim milk, fructose, gelatine 60 and 150 Bloom, and gum arabic, was evaluated to determine their capabilities for retention of ethanol as a model volatile, under different …

Effect of Digestion Processes on Dewatering and Bound Water Content of Sludge
… media at high temperatures, resulting in the formation of a skin layer that hinders efficient dewatering. The first part of the study has looked at various digestion processes and how they affect the skin formation phenomenon. The results showed that temperature played a significant role in …

Film Formation via Drying of Polymer Solutions
Drying of skin and personal care products, to create thin films, is a process employed to deliver product-specific functions to targeted areas. Uniform, defect-free films are essential, as defects and instabilities can adversely affect product performance. To optimise product functionality, …
