About Girish Venkatachalapathy:

I have experience
in providing performance insights
through CFD and heat transfer
simulations/ analysis, to enable
design improvements for a wide
range of applications. My strengths
are understanding stake-holder
high-value problems, streamlining
them into simulation requirements,
and adopting Systems Engineering
principles in integrating
Computational Modeling with product
development and real-time system
diagnostics and control. I am a quick and continuous learner,
interested in exploring and adopting
innovative, hybrid modeling
techniques for application based
R&D/engineering. 

Experience

Aug 2020 - Present : Computational Modeling Engineer - Applied Materials, Bangalore, India 

  • Achieved real-time system diagnostics/control & optimized prod-
    uct development cycles by building state-of-the-art Thermal Dig-
    ital Twins (DTs) for semiconductor manufacturing processes.
  • Supporting hardware development through 2D and 3D CFD simulations
    to study heat transfer, flow and reactions in improving energy ef-
    ficiency, gas delivery system design and chemical deposition for
    chip manufacturing.
  • Developed Hybrid Modeling techniques for DTs- Physics Based
    Network Models for Heat Transfer between different chamber
    components, Modeling Surface-2-Surface Radiative Heat Transfer
    using 3D View Factor Calculations, Statistical/Regression Based
    Models for faster real-time digital virtual simulation response. Re-
    duced Order Models for better turnaround times (In Progress). 
  • Achieved within 2% accuracy using DT results in comparison with
    real-time transient on-field data. Scripting & automating data
    exchange between different hybrid models. Integrating simula-
    tions with real-time Sensor input data, to provide live actionable
    insights and improve process efficiency/yield.

Mar 2017 - Jul 2020 : CFD Application Engineer - Simerics Inc., Bangalore, India.

  •  Devised 2 times faster, accurate and robust simulation method-
    ologies using Simerics-MP+/PumpLinx solver for different appli-
    cations:
    – Multiphase: Automobile coolant filling, gear splashing, ma-
    rine hull hydrodynamics
    – Conjugate heat transfer: Heat exchangers, e-motors, engine
    piston cooling, PCB thermal performance
    – Fluid Machines: Centrifugal and Positive Displacement
    pumps, Turbines and Valves
  • Technical Marketing, Pre-sales and support: First Point-Of-
    Contact for CAD-CFD integrated solutions/products.
  • Strategized the process, format and reviewed the complete CFD
    Help documentation as Subject Matter Expert.

Education

  • Master of Science (Mech Engg.) - Fluid Mechanics - Delft University of Technology, The Netherlands (2014 - 2016)
  • Bachelor of Mechanical Engineering - SSN College of Engineering, Anna University, India (2010 - 2014).
