Journal of the American Oil Chemists' Society, EarlyView.ABSTRACT Palm oil, which is extracted from the mesocarp of the fruit of the Elaeis guineensis Jacq. palm tree, is the most widely produced vegetable oil in the world. The extraction of this substance typically utilizes the conventional pressing method, a technique that is advantageous due to its low operating cost and simplified process.

On some physics to consider in numerical simulation of erosive cavitation
, 2009 This paper discusses some hydrodynamic mechanisms in erosive cavitation, which are all important to capture, and consider, when assessing the risk of erosion, by numerical simulations or model tests in a cavitation tunnel.

Evaluation of incipient cavitation erosion for pipe wall at downstream of an orifice [PDF]
, 2009 Cavitation induced vibration and the consequent erosion of pipes are the potential damaging factors in the piping systems. In order to prevent such trouble, it is preferable to develop a detection method for cavitation occurrence.

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT This study presents the design and construction of an experimental system for evaluating the thermal performance of heat pipes, using sintered‐wick heat pipes charged with CuO nanofluids. The device used in this study is a sintered‐wick heat pipe, in which the liquid return is driven by capillary forces within the porous wick structure.

Fission of Collapsing Cavitation Bubbles [PDF]
, 2001 High-speed observations (for example, Lauterborn and Bolle 1975, Tomita and Shima 1990, Frost and Sturtevant 1986) clearly show that though a collapsing cavitation bubble approaches its minimum size as a coherent single volume, it usually reappears in ...

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Combining electrochemical and advanced oxidation processes (AOPs) has greatly mitigated the limitations of electrocoagulation (EC) in water treatment. This study examined the effectiveness of sonolysis (US)‐assisted alternating current (AC)–EC in reducing fluoride (F¯) from landfill leachate wastewater (LLW), with measurements of electrical ...

Effects of Model Size and Free Stream Nuclei on Tip Vortex Cavitation Inception Scaling
, 2001 Because of the complexity of the flow field in a trailing vortex, prediction of tip vortex cavitation inception on a hydrofoil or a propeller still relies heavily on model tests and application of cavitation scaling.
