• Identified and modeled a solution for problem occurring in a commercially produced Anemometer by NRG systems. • The Anemometer had post calibration errors, problem being identified as precessional rubbing at contact surfaces (bearings). The idea was used to investigate similar phenomena in real sized Turbomachinery bearings. • Modeled mathematical model for such a case and analyzed it for its vibrations signatures. • Whipping and whirling frequencies (Reason for anemometer error) were analyzed and validated using a nonlinear time transient analysis for the same model Project -Precessional Whip and Whirl Characteristics for a model with contact at 2 rub locations for rigid rotor supported on a elastically supported rigid stator.

Modelling and Finite element analysis




Dynamic Modelling results, Fast Fourier transforms, intergrator functions, cell array, string array's and other important mathematical functions


Designed and developed CAD models for GEOSUN (hybrid geothermal+solar) air conditioner, Homemade CNC, Kiosk and Part/Assembly models using SolidWorks.


Mechanical Graduate with a proclivity towards innovative ideas and interests in design and machinery. • Developed a model for rubbing at bearing contacts to study precessional rub phenomenon exhibited by anemometers and extended this study to real size Turbomachines. • Designed a reaping tool which replaced conventional rotary mechanism with a reciprocatory one (increased efficiency). • Designed pressure vessels as an intern at Larsen and Toubro (oil and gas special project division). • Expertise in using automated mathematical solutions, to simulate motion/stresses for various projects.


Seeking a challenging position in the field of Mechanical Engineering that will enable me grow and nurture my potential, provide a practical, industrial perspective to my academia, and facilitate me to make a momentous contribution to the accomplishment of corporate goals.
