This document outlines a final project presentation for a mechanical engineering student. The project aims to investigate total pressure distortion patterns downstream of a distortion screen and identify the aerodynamic inlet plane ahead of a compressor. The methodology involves obtaining geometric details of an experimental facility, meshing the fluid domain, imposing boundary conditions from experiments, and obtaining flow solutions using simulation software. Results will be validated with experiments. The presentation covers the project objectives, literature review on distorted intake flows, validation studies, simulation design, solution procedure, results and discussions, conclusions, and suggestions for future work.

Aim :
To investigate the total pressure distortion pattern
downstream of the distortion screen and to identify the
Aerodynamic Inlet Plane ahead of the compressor.
Objectives :
• To study the total pressure distortion decay pattern in the
intake.
• To study the variation of distortion index downstream of
distortion screen.
• To identify the Aerodynamic Inlet Plane.

Methodology
• The geometric details of the experimental facility and the
distortion screen developed at the National Aerospace
Laboratories was obtained.
• The fluid domain was meshed using GAMBIT.
• The boundary conditions were imposed from experimental
conditions.
• The flow solution was obtained by FLUENT.
• The results will be validated with the experiments to be
conducted at the National Aerospace Laboratories.

Summary of Literature Review
• It was concluded from the existing literature that a
fundamental fluid dynamic understanding of the distorted
flow-field in intakes is lacking.
• The literature reveals the need for improved flow-field
analysis in improving the design of distortion screens to
generate required distortion pattern.
• The flow-field analysis in distorted intakes have been
limited so far to experimental methods. The limitations of
the experiments lies in the fact that obtaining intricate flow
features is rather complex, and if so desired requires
exhaustive instrumentation.
Briefly describe the essence of literature review, highlighting
the salient points observed
