Modeling of contact between liner finish and piston ring in internal combustion engines based on 3D measured surface
… challenge for this single equation is that real plateau roughness makes it unreliable. As a result, micro geometry of liner surface needs to be obtained through white light interferometry device or confocal equipment to conduct contact model. Based on real geometry of liner finish and the …

Thermo-mechanical stress measurement and analysis in three dimensional interconnect structures
… prediction of stress behavior according to the real geometry of the sample. The conventional Raman method is used to measure the linear combination of in-plane stress components near silicon top surface Secondly, the limitation of conventional Raman method is discussed: only certain linear …

Unsteady flows in cantilever compressor stator tip clearances and the effect of real tip geometry
… derivative of ±30%. The combined effect of blade geometry and radiused tip geometry results in a maximum clearance derivative in line with experimental studies. Thus real geometry is shown to be a likely cause for the remaining discrepancy in clearance derivative between experimental and …

Trailing Edge Aerodynamics: Flow Regimes, Geometry and Loss
… were in the same flow regime. The effect of geometry variation on blown, through trailing edge holes geometries is investigated experimentally. These geometries undergo transonic vortex shedding when there is no trailing edge blowing, but the addition of coolant to the base region is able to …

Manufacturing Variability in High Pressure Turbine Rotor Blades
… is the ability to process the measurements of real blades. Structured-light scanning was used measure the manufactured blades and geometry processing scripts were developed to extract the manufacturing variability once the blades were aligned to the design-intent coordinate system. The …

A new experimental approach of characterizing two-phase flow and heat transfer in plate heat exchangers
… diluted by the increased number of plates in real applications, it could be significant when the number of plates is small, as is often the case in laboratory settings for the development of heat transfer correlations. The two-phase flow regime is then investigated in a 2-channel FPHE under …
