Developing a Navier-Stokes fluid dynamics solver(Fastest-3D). Simulating 1D and 2D laminar flames with detailed chemistry.

Worked as scientific assistant(Wissenschaftlicher Mitarbeiter) Numerical investigation of unsteady lean premixed combustion in combustion chamber of gas turbine.

• Design of different geometries for the combustion chamber using CAD software • Generation of a computational grid of the corresponding geometries for simulation of the flow • Numerical simulation of the non-reactive flow through a swirl stabilized combustion chamber using a Navier-Stokes solver (ANSYS-CFX)

• Defining the overall size of the annular channel for the blades(hub diameter, casing diameter, speed of the shaft) • Creating the shape of blades and vanes from points describing airfoil shapes • Positioning the blades and vanes in the annular channel by using 1D- or 2D-computer solvers (Hearsey75) for the flow in the meridional plane (S2). • Grid Generation for the designed geometry, using “NUMECA Auto grid” • Off-design computing of the design point condition with a 3D-flow solver (ANSYS-CFX) with the i
