2D Numerical Study on the Flow Mechanisms of Boundary Layer Ingestion through Power-Based Analysis
This paper aims to establish an approach of power bookkeeping in a numerical study. To study the process of power conversion coursed in the flow field, the methodology employs a power-based analysis to quantify power terms. This approach is examined in a

Feasibility study of an induction motor rim drive for an aircraft boundary-layer-ingestion fan
This study presents a feasibility study for an induction motor rim drive to power aircraft boundary-layer-ingestion (BLI) fans. The design is developed from a BLI-fan specification for traditional aircraft architecture: the rotor is fastened to the rim ...

Improvement of the Parallel Compressor Model and Application to Inlet Flow Distortion
This paper introduces a semi-analytical approach which enables one to deal with distorted inflow in axial fans or compressors. It is inspired by the classical parallel compressor (PC) theory but relies on a local flow-loading coefficient formalism. It is
