: Variable geometry can introduce "additional losses" compared to fixed designs, such as vane tip leakage .
: By changing the flow area at the turbine inlet, the system can maintain high efficiency even when the "available head" or discharge varies. Variable Geometry Turbine Technology for Marine...
1. Introduction
: Fixed-geometry turbines often struggle with efficiency at low working conditions or during rapid load changes. critical for naval operations.
: Research focuses on optimizing vane turning angles to balance these leakage losses against the aerodynamic gains. Variable Geometry Turbine Technology for Marine...
: Significantly improves acceleration and deceleration characteristics, critical for naval operations.
