Design and analysis of Combustion nozzle with Multiphysics study using ANSYS
The Project was undertaken as my Multiphysics study capability which aimed at studying the fluid structure interaction of the combustion nozzle. The results obtained were the interaction between fluid flow and the nozzle structure in real time.

Results
Fluid flow
The fluid flow results are represented using particle tracking method. The fluid shown in the renders are the chemical reaction based outputs of CH4 , H2, O2. The reaction inputs given in to the system by creating the CHEM KIN reaction file and the energy change during flow are all based on the reaction input.
