RISZonal Detached Eddy Simulation of the Fan-Outlet Guide Vanes Stage of a Turbofan Engine: Part II—Broadband Noise Predictions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper (Part II) presents the broadband noise predictions of a turbofan stage based on a hybrid method proposed by ONERA in the framework of the European project TurboNoiseBB. The numerical approach relies on a ZDES ...
Loss Assessment of the NASA Source Diagnostic Test Configuration Using URANS With Phase-Lagged Assumption
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This article presents the study of the Source Diagnostic Test fan rig of the NASA Glenn (NASA SDT). Numerical simulations are performed for the three different outlet guide vane (OGV) geometries (baseline, low count, and ...
Tonal Noise Prediction of a Modern Turbofan Engine With Large Upstream and Downstream Distortion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Ultra-high bypass ratio (UHBR) engines are designed as compact as possible and are characterized by a short asymmetric air inlet and heterogeneous outlet guide vanes (OGVs). The flow close to the fan is therefore ...
