This project focuses on the Computational Fluid Dynamics (CFD) simulation of the Boeing 757, a narrow-body twinjet originally developed in 1978 as the successor to the 727. The aerodynamic analysis is conducted in ANSYS Workbench using a high-resolution mesh of 17.6 million elements. Fluid flow is evaluated at an inlet speed of 45 m/s using the k-epsilon turbulence model. Ansys Workbench (.wbpz) file is attached for download.
