Aim and Objectives of the Project

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.

• To study the effect of scaling on distortion index.

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

Validation Studies

Validation studies were conducted on a square grill whose geometry

is shown below. Distortion indices and loss coefficients were

evaluated at various planes downstream of the grill for various inlet

Mach numbers.
