Dry sump lubrication is a key feature in transmission systems of high-performance racing
applications. While it provides adequate oil for gears contact, it reduces churning losses.
Moreover, provision of continuous oil for gear contacts in harsh conditions during a race,
makes dry sump lubrication systems more reliable. One of the most important aspects of any
dry sump system is the assessment of its thermo-tribological performance and its capability to
remove the generated heat from highly loaded high shear gear contacts. In this paper, a multiphysics integrated numerical method of a dry sump transmission, considering a system
approach is presented. The method provides a validated predictive tool to assess thermal
functioning of dry sump lubrication systems
