The main intention of this project is to do
relative analysis of Drag Reduction over Blunt Bodies at
varied Angles of Attack in Supersonic Flow. In this
project we have taken plain blunt body attached with
different types of spikes which are like as 1. Blunt nose 2.
Conical spike 3. Flat faced aero disc 4. Hemispherical
spike 5. Breathing Blunt nose. For competitive analysis
and results based on the different angle of attack with 0,
5 and 8 on that blunt body with spikes. Numerical
simulation was carried out using CFD with SST komega model adopted. The hemispherical body is found
to be efficient for reducing pressure in vicinity of blunt
nose, while the flat plate found to be efficient in reducing
peak pressure in compare to other. However, from the
values of drag coefficient for all configuration the conical
body is observed to have effective drag reduction
compare to other bodies.
