Modelling of A Boundary Layer Ingesting Propulsor [PDF]

Energies, 2018
Boundary layer ingestion is a promising method to decrease the propulsive power consumption of an aircraft, and therefore the fuel consumption. This leads to a reduced environmental impact and an improved cost-efficiency. To get a better understanding of

2D Numerical Study on the Flow Mechanisms of Boundary Layer Ingestion through Power-Based Analysis

Aerospace, 2022
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

Numerical Investigation on the Effect of Height-to-Radius Ratio on Flow Separation Features in S-Shaped Diffuser with Boundary Layer Ingestion

Aerospace, 2023
The flow separation occurring in the S-shaped diffuser with boundary layer ingestion (BLI) has a significant effect on the performance of the embedded engine. Previous studies have found that the area ratio (AR) as well as the length-to-offset ratio (LOR)

Aeroacoustics of the propeller Boundary Layer Ingestion configuration for varying thrusts

Journal of Sound and Vibration
The Boundary Layer Ingestion (BLI) configuration is a promising installed propulsion arrangement for aircraft owing to its potential to boost aerodynamic efficiency. However, it is prone to generate additional noise as the inflow to the propulsion system is non-uniform and turbulent due to the ingested boundary layer.

Aerodynamics of Boundary Layer Ingesting Fuselage Fans [PDF]

Journal of Turbomachinery, 2021
Abstract Boundary layer ingestion (BLI) potentially offers significant reductions in fuel burn and pollutant emissions. The propulsive fuselage concept features a fan at the back of the airframe that ingests the 360 deg fuselage boundary layer. Consequently, the distortion at the fan face during cruise is close to radial.
