Abstract: Fatigue data on a 5456-H117 aluminum alloy have been obtained in air and sea water by fracture mechanics methods. It is found that the presence of sea water increases the crack growth rates ...

Abstract: Stress corrosion cracking of a 7079-T6 aluminum alloy in seawater was investigated by bend tests of smooth and precracked specimens. It was found that there was a general agreement between ...

Abstract: Notch-tensile tests were conducted on four quenched and tempered steels to study the effect of carbon content on notch toughness. The toughness was found to decrease when the carbon content ...

Abstract: This work investigates the constant-pressure consolidation characteristics of three different sludge samples, with particular emphasis on the tertiary consolidation stage. The refined Terzaghi-Voigt rheological model is ...

Abstract: This work investigated the effects of cationic polymer flocculation on the continuous moisture distributions of two sludges by means of combined thermal gravitational analysis and differential thermal analysis tests. At a ...

Abstract: In this paper, a three-dimensional numerical investigation was performed for heat transfer characteristics and flow structure of full scale fin-and-tube heat exchangers with rectangular winglet ...

Abstract: This work examines the thermal pyrolysis characteristics of polyelectrolyte-flocculated activated sludge at a heating rate up to 873 K by means of thermogravimetric analysis (TGA). Although the polyelectrolyte does not ...

Abstract: In this work we investigated the use of a short time, low superheat boiling process to treat biological sludge. The treated sludge would exhibit a deteriorated filterability, and a marked increase in soluble organics ...
