 — 
August 2024
Spirotech Heat Exchangers Pvt. Ltd. | LU-VE group

Responsible for design and development of Heat Exchangers.

  • Spearheaded New Product Development (NPD) for 5+ high-value thermal exchange units, managing the engineering cycle from prototyping to mass production.
  • Conducted techno-commercial feasibility analyses to assess manufacturing viability, proposing alternative designs that aligned with plant capabilities and reduced production costs.
  • Served as the technical liaison for key clients, translating complex thermal requirements into actionable engineering specifications for the product development team.
  • Ensured product compliance with international safety standards, including the Pressure Equipment Directive (PED), aligning designs with rigorous regulatory frameworks.

Projects

Computational Fluid Dynamics (CFD): Aerodynamic Analysis of 3D Lifting Surface
July 2025
 — 
July 2025

An incompressible, steady state, simulation study of a rectangular wing in 3D space using OpenFOAM.

  • Executed a steady-state RANS simulation on a rectangular wing (Clark Y) using OpenFOAM and the k-omega SST turbulence model to analyze external flow.
  • Validated the results againt the XFOIL results as benchmark and recorded a drop in lift coefficient from 0.83 in XFOIl to 0.55 in RANS. These effects can be attributed to the production of wing tip vortices in the 3D case.
  • Explained the lift loss to Finite Wing Theory and induced drag from wing-tip vortices, verifying the result against Prandtl’s Lifting-Line prediction
  • Tools: OpenFOAM, snappyHexMesh, ParaView, Python (Data plotting).
Thermal System Design: Parametric Cycle Analysis
September 2025
 — 
September 2025

Analysis of an AC system of 1TR(~3.5kW) capacity using analytical and numerical methods.

  • Developed a numerical solver for a 1TR Vapor Compression Cycle using Python (CoolProp/NumPy) to automate thermodynamic sizing.
  • Each component of the system is modelled individually and used in further study of the whole system
  • Tools: Python, CoolProp, NumPy, SciPy, Matplotlib
