WORK EXPERIENCES

Research Assistant, Aerospace Computational Methods Lab, Syracuse

Fitted Airfoils and Optimized Geometry Jan. 2015 – May 2015

Achieved the object building the geometry quickly and modifying the airfoil geometry intuitively.

Optimized round nose airfoil representation method with Kulfan’s method-“CST”, used less number of design variables and generated the geometry smoothly.

Fitted target airfoils with Newton Method and Levenberg-Marquardt Algorithm in MATLAB, outputted the coefficients of the shape function. The LM method reduced the generation time from 200s to 20s, with a very low error of 10e-5.

Perfiled a User-Defined Primitive (UDP) with C using Kulfan’s representation method, inputted it to the open source system Engineering Sketch Pad (ESP).

CAD Drawing By Programming Aug. 2014 – Dec 2014

Plotted the Robin Helicopter in MATLAB with the super-ellipse equations.

Transferred the MATLAB program to Engineering Sketch Pad (ESP) prefile to generate the Robin Helicopter without setting branches.

Outputted the body shape to validate the capabilities of the Parallel Unstructured Maritime Aerodynamics (PUMA) flow solver.

CAE/CFD Internship, China Automotive Technology & Research Center, Tianjin, China

Jun. 2014 – Jul. 2014

Checked the incorrect connection and interval in autocleanup panel, which were showed by red free edges

Stitched all the free edges with toggle subpanel by setting different tolerance

Created the lost faces and deleted the duplicate faces so that we could generate mesh only on outside faces

Optimized CAD model to generate mesh for many automobile parts with HyperMesh and Star-CCM+

Performed CFD analysis on body structure and exhausted system using Star-CCM+ to get the aerodynamic force distribution and the pressure distribution

Reduced wind resistance and energy consumption for SUVs by conducting CFD analysis on the body structures and making re-design based on the results
