An investigation to predict the sub-atmospheric pressure on high spillways
… based on previous experiences. Every case is subjected to a physical model study. It seemed necessary to systematize the evaluation of the flow field and the pressure distribution on the crests of spillways. The investigation of the subatmospheric pressure which is the main cause of cavitation …

Experimental and Numerical Study of Dual-Chamber Thermosyphon
… experiments were carried out using water at sub-atmospheric pressures of 9.7, 15 and 21 kPa with a three-dimensional porous boiling enhancement structure integrated in the evaporator. Sub-atmospheric pressure boiling achieved heat fluxes in excess of 100 W/cm2 with negligible incipience …

Oil Transport in Piston Ring Assemblies
… where the lubricant film thickness, oil film pressure and friction were simultaneously measured throughout the stroke as a function of speed, load and temperature. Furthermore, laser induced fluorescence (LIF) was used to identify the onset of cavitation occurring in the diverging part of the …

Reactivity Studies of Tridhydropyridine Radical Cautions by using Fourier-Transform Ion Cyclotron Resonance Mass Spectrometry and Advancement of Mass Spectrometric Analysis of Asphaltenes and Degradation Products
… This dissertation reports the utility of atmospheric pressure chemical ionization(APCI) tandem mass spectrometry for the identification of compounds containing the 3-phenylallyl alcohol moiety in lignin degradation product mixtures. This method was needed because most lignin degradation …
