Influence of Inlet and Outlet Area Ratio on Intake Port Flow Capacity
International Journal of Rotating Machinery, Volume 2024, Issue 1, 2024.The flow capacity of the intake port has a great influence on the charging efficiency of the internal combustion engine, affecting the engine’s performance, so it is critical to improve the intake port flow capacity. In this paper, the intake port numerical model was established, and the influence of the inlet and outlet area ratio on intake port flow ...

Off-design considerations through the properties of some pressure-ratio line of radial inflow turbines [PDF]
, 2008 Radial turbines are commonly used in applications involving operation through severe off-design conditions. The emergence of variable-geometry systems leads to the distinction between two off-design concepts: operational and geometric off-designs.
