Modeling engine oil vaporization and transport of the oil vapor in the piston ring pack on internal combustion engines
A model was developed to study engine oil vaporization and oil vapor transport in the piston ring pack of internal combustion engines. With the assumption that the multi-grade oil can be modeled as a compound of several distinct paraffin hydrocarbons, a set of equations governing the oil vapor …

Refrigerant flow distribution in vertical headers of reversible microchannel heat exchangers
… system. In heat pump mode, it functions as an evaporator and refrigerant maldistribution among parallel microchannel tubes creates unwanted superheated region, which lowers the heat transfer between refrigerant and air. This thesis presents the experimental and modeling study of refrigerant …

Molecular dynamic simulation of pool boiling process
… for water by surface tension and liquid - vapor density calculation. Water-copper interaction was parametrized based on contact angle of water droplet on the copper surface. Analysis of pool boiling indicated a significant difference between heat transfer coefficient calculated from …

Laserstrahlquellen auf Basis eines neuartigen Neodym-dotierten Mischgranats für Wasserdampf-DIAL-Systeme bei 935 nm
… certain trace gases in the atmosphere like water vapor using the Differential Absorption LIDAR (DIAL) technique pulsed single frequency laser sources are required which can be tuned to certain absorption lines of that gas. A special set of four wavelengths between 935.561 and 935.906 nm is …

Three-dimensional water vapor retrieval using a network of scanning compact microwave radiometers
… (2-5 km). Therefore, measurements of water vapor aloft with high time resolution and sufficient spatial resolution have the potential to improve forecast skill for the initiation of convective storms. Such measurements may be used for assimilation into and validation of numerical weather …
