Graduated in Aerospace Engineering with focusing in Design Analysis & a work experience of 2 years in Manufacturing Industry. EDUCATION

Masters of Science, Mechanical and Aerospace Engineering Aug 2015- Sept 2017 University at Buffalo, The State University of New York (GPA- 3.5/4.0) Bachelor of Technology, Mechanical Engineering July 2009- May 2013 Veermata Jijabai Technological Institute, University of Mumbai, India (GPA- 7.0/10.0) ENGINEERING PROJECTS IN GRADUATE COLLEGE:

(Masters Project) Computational Investigation of Passive surface flow control features for aerodynamic efficiency: The objective of the project was to delaying the flow separation of the boundary layer and increase the Lift/Drag ratio by introducing passive surface flow features like riblets. Both 2D and 3D CFD simulations were run for airfoils NACA 4412 and NACA 0012 in ANSYS Fluent. A set of Design of Experiments (DOE) were simulated in 2D & 3D by changing the parameters of the riblets. The CAD models for the DOE were developed using SolidWorks and MATLAB was used for Lift/ Drag prediction by using Surrogate Model of the DOE data.

Developed a CFD code in MATLAB for a uniform, inviscid subsonic flow governed by 2nd order PDE that hits a one period sign wave wrinkle in the metal skin of the wind tunnel by numerical simulation using Successive Over Relaxation method

(SOR) and Alternating Direction Implicit method (ADI).

Developed a CFD code in MATLAB to solve a dam break problem using 1-D shallow-water equations. The numerical schemes used were the 2nd order MacCormack method, Modified Runge Kutta method with TVD (Total variation diminishing scheme), 1st order Gudonav scheme and 3rd order ENO (Essentially non oscillatory) scheme.

Analyzed the distribution of size, temperature, velocity and distance of an evaporating water droplet using MATLAB.

Developed a MATLAB code for image segmentation using Distance Regularized level set evolution (DRLSE) for Medical application like Sonographic images, MRI

Developed a GUI in MATLAB for transformation (translation, rotation, shear, scale) of a 2D geometry as sketched by user. This was achieved by using different GUI objects which were linked to functions in which appropriate transformation matrices was coded.

Modeled a CNC machine and implemented a trajectory planning scheme on it. The trajectory planning scheme was developed using a sequence of parametric curves and 2D transformations in MATLAB while the CAD model was created in Autodesk Inventor and the dynamic simulation environment was used for tracing the trajectory.

Analyzed Fluid Structure Interaction on Wind Turbine Blade using ANSYS Fluent & ANSYS Mechanical. The blade was modelled using SolidWorks. ANSYS Fluent was used to simulate the steady state flow around the wind turbine blade using rotational frame of reference and the pressure load data was transferred to ANSYS Mechanical to obtain the deformation and stresses.

Designed a Power Box Chassis for a computer using Sheet Metal tools in SolidWorks.

Created CAD component and assembly of hydraulic pump in SolidWorks.

Designed a Car wheel rim in SolidWorks and did FEA structural analysis in ANSYS Mechanical. PUBLICATIONS:
