Job Summary

Expertise in CFD and Scramjet Combustion. The ideal candidate will have a deep understanding of Combustion concepts, turbulence-chemistry interaction models, chemistry solvers. Reaction Kinetics modeling using Chemkin and possess excellent problem-solving skills to deliver high-qualitysimulations for various projects. Function as a solution specialist in the field of Computational Fluid Dynamics using simulation tools such as ANSYS FLUENT, Chemkin or Star CCM+.

Key Responsibilities
- Perform high-fidelity CFD simulations of high-speed reactive flows in scramjet and ramjet engines using tools such as ANSYS Fluent and ANSYS Chemkin, capturing coupled effects of fluid dynamics, combustion, and heat transfer.
- Model combustion kinetics and fuel–air mixing under supersonic and hypersonic flow conditions, incorporating finite-rate chemistry, turbulence chemistry interaction, and high-temperature gas effects.
- Develop and validate detailed or reduced chemical kinetic mechanisms for hydrogen, hydrocarbon, or multi-species fuel systems to predict ignition delay,



flame structure, and combustion efficiency accurately.
- Simulate high-enthalpy flow environments, accounting for thermochemical nonequilibrium, dissociation, recombination, and radiation effects relevant to hypersonic combustion systems.
- Analyze shock–combustion interactions and shock-induced ignition phenomena, studying flame stabilization, pressure rise, and thermal choking effects within scramjet isolators and combustors.
- Conduct parametric and design studies to optimize fuel injection strategies, mixing enhancement techniques, and combustor geometries for improved efficiency and reduced total temperature and wall heat loads.
- Generate high-quality meshes and ensure grid independence for reactive flow regions, capturing boundary layers, shear layers, and flame fronts accurately in complex combustor geometries.
- Apply and compare turbulence and combustion models (RANS, LES, DES, Flamelet, PDF
