NUMERICAL CALCULATION ANALYSIS AND CHARACTERISTIC RESEARCH ON WINDAGE LOSS OF OIL-JET LUBRICATED AVIATION GEAR PAIR

Numerical Calculation Analysis and Characteristic Research on Windage Loss of Oil-Jet Lubricated Aviation Gear Pair

The VOF (volume of fluid) multiphase transient simulation model of the windage loss of the gear pair under oil-jet lubrication was carried out by using the dynamic mesh technology with the powerful parallel computing capabilities of the Super Cloud Computing Center.Firstly, a two-phase (oil-gas) turbulence numerical model was established in the pro

Modeling an Alternate Operational Ground Source Heat Pump for Combined Space Heating and Domestic Hot Water Power Sizing

This study developed an alternate operational control system for ground source heat pumps (GSHP), which was applied to determine combined space heating and domestic hot water (DHW) power equations at design temperature.A domestic GSHP with an alternate control system was implemented in a whole building simulation model following the heat deficiency
