Fundamental Research on Advanced Gas Turbine Manufacturing  

Objective: As more power is demanded aircraft engines and industrial gas turbines, turbines have to operate under higher temperature and pressure, which requires superalloy to be manufactured into blades with columnar or single crystals structure by the directional solidification method. Some solidification defects (such as freckles) caused by natural convection exert a strong impact on turbine blades’ mechanical performance under high temperature. Such natural convection-induced defects are closely related to the melt flow form and solidification interface morphology. Therefore, the prediction and control of the melt flow become the primary issue to be solved for high-quality blades.
Methodology: The top priority was to establish multi-physics simulation approach to CFD modeling of directional solidification processing using Computational fluid dynamics (CFD)-Ansys Fluent.  In order to reduce or even eliminate freckles, the external traveling magnetic field was employed to control melt flow during the directional solidification process. Next, ANSYS-emag is used to simulate Lorentz force produced by traveling wave magnetic field during solidification.
Outcome: A range of magnetic fields is obtained to control solidification defects-Freckles.

Control of Vortex Shedding behind a Circular Cylinder Using a Combination of Slot & Control plates

Objective: Present numerical study aims at suppression of vortex shedding formed over a circular cylinder using different combinations of slot and control plates.
Methodology: Unsteady, two–dimensional computations are carried out for laminar, isothermal conditions at a Reynolds number (Re) of 150 using commercially available CFD software ANSYS-FluentTM.
Numerical simulations with different passive controlling methods have been carried out to reduce the vortex shedding frequency or to suppress it completely by using the configurations, such as a cylinder with control plates, and cylinder with combinations of slots and control plates.
Outcome: By carefully comparing the numerical results of all the cases, it is found that cylinder with control plates at 5° angle is the best case where the vortex shedding is completely suppressed which in turn reduces the drag force significantly.
However, in other cases, it was partially suppressed but increases the drag force due to vortex formed near to the control plates or not having any effect on vortex shedding. The results are presented in terms of vorticity and streamline contours, Cl, Cd and Strouhal number.

It is also shown that for a fixed value of aspect ratio, the convective heat transfer is decreased for the Nanofluid when compared with that of base fluid due to an increase in thermal conductivity of the Nanofluid.

Objective: The objective of this project was to analyze the aerodynamic characteristics, at different flow conditions (Reynold’s number and angle of attack), of a Light sports aircraft using Ansys Fluent.  We were also required to make geometrical modifications to the current design and analyze the change in the aerodynamic characteristics.
Methodology: The results obtained here were compared with analytical results that were achieved by us in one of the previous courses. As the geometry was made available to us as an STL file, we imported the geometry and started by running simulations to find mesh independency and domain independence. To simplify the meshing process, a meshing-wrapping scrip that wraps up the whole aircraft was used.  After finding the domain and mesh independence, our team was divided and I was in-charge of designing the landing gear (as the geometry given to us didn’t have landing gear) and adding sponsons.
Outcome: As expected, it was observed that the addition of landing gear decreased the aerodynamic characteristics, however, the addition of sponsons increased the aerodynamic characteristic by a significant margin.
