Heavy Duty Engine Piston Cooling Gallery Oil Filling Ratio Measurement and Comparison of Results With Simulation

Volume 1, 2018
Pistons for heavy duty diesel applications endure high thermal loads and therefore result in reduced durability. Pistons for such heavy duty applications are generally designed with an internal oil gallery — called the piston cooling gallery (PCG ...

Thermo-Optical Tuning of Whispering Gallery Modes in Microspheres around the 85Rb Cooling Transition

Frontiers in Optics 2009/Laser Science XXV/Fall 2009 OSA Optics & Photonics Technical Digest, 2009
We present a method for tuning whispering gallery modes in microspheres and demonstrate tuning to the cooling transition of85Rb. The tuning method can be used in UHV and is of interest for cavity-QED experiments.

Development of an Oil Gallery Cooling Model for Internal Combustion Engines Considering the Cocktail Shaker Effect

Numerical Heat Transfer, Part A: Applications, 2009
An internal combustion engine oil gallery cooling model was developed, which can predict average heat transfer coefficients by considering the cocktail shaker effect due to the reciprocal motion of the engine piston. The model prediction showed good agreement with available experimental data.

Cooling the mechanical motion of a tapered optical fiber and a microsphere-cantilever using whispering gallery modes

SPIE Proceedings, 2016
Light coupled from a tapered optical fiber is used to excite the morphology dependent whispering gallery mode (WGM) resonances of a silica microsphere-cantilever. Using the optomechanical transduction from the WGM supported by the microsphere1, we can simultaneously detect the thermal Brownian motion of both the microsphere-cantilever and the tapered ...

Thermo-Optic Tuning of Whispering Gallery Modes in Microspheres to the 85Rb Cooling Transition in a Vapor Cell

Frontiers in Optics 2010/Laser Science XXVI, 2010
We demonstrate a method for tuning whispering gallery modes in microspheres to the cooling transition of85Rb in vacuum. The ability of this device as a sensitive atom-optic sensing tool is presented for bio-sensing applications.

Numerical Investigation into the Cooling Process of Conventional Engine Oil and Nano-Oil Inside the Piston Gallery

2012
A numerical simulation model has been developed for the transient flow and heat transfer problems of oil inside the piston gallery using a coupled VOF/Level Set method. Detailed cooling processes of Cu-oil nanofluids, with the nanoparticle size of 50 nm and the volume fractions of 1, 2 and 3 %, have been investigated.
