NUMERICAL AND EXPERIMENTAL INVESTIGATION OF FLOW IN AN AFTERBURNER

By Suresh Kumar S (ME02S004)

Project Objective…

 Optimization of flame stabilizer location in an aero engine gas turbine afterburner w.r.t. flame stabilizer.  Experimental investigation of flow in a model afterburner and comparison of results with the code.

Geometry Creation goes in this way..

The geometry was created using the modeling software named CATIA.
