MODELING OF ACOUSTICALLY TREATED NACELLE LIP TRANSPIRATION FLOW ANTI-ICING SYSTEM

摘要

Acoustically treated nacelle lip transpiration flow anti-icing system is analyzed by solving the two dimensional transient heat conduction equation with a combined transpiration flow convective heat transfer and thermodynamics energy transfer rate boundary condition. The nacelle lip skin surface temperature distribution is determined when the skin exposed to airflow laden with atmospheric cloud super cooled water droplets of known size distribution is heated using transpiration air flow.
