TI-GPR for Improved Prediction of VIGV Pump Operating Characteristics under Sparse Data Conditions
Variable inlet guide vane (VIGV) control is among the most energy-efficient flow regulation methods for axial pumps because it adjusts the inlet swirl angle directly while preserving high hydraulic efficiency. However, unlike rotational-speed control, whose performance curves scale straightforwardly through the affinit...
