Junior ANSYS CFD Engineer

3 days ago

Palakkad, Kerala, India Hyetron Energy Full time ₹ 4,00,000 - ₹ 8,00,000 per year

Location: IIT Palakkad, Kerala

Employment Type: Full-Time

Experience Level: 1–2 Years

About the Role:

We are seeking a Junior ANSYS Engineer with a strong foundation in Computational Fluid Dynamics (CFD) and a passion for electrochemical systems, particularly electrolysis. This role emphasizes multiphase flow modelling, where you will simulate complex interactions between gas and liquid phases within electrochemical devices. A key focus will be on generating high-quality meshes and configuring solvers to accurately capture the physics of multiphase transport, bubble dynamics, and flow distribution in electrolysis cells.

Key Responsibilities:

  • Develop and execute CFD simulations for multiphase flow in electrolysis systems using ANSYS Fluent or CFX.
  • Create and refine structured, unstructured, and hybrid meshes for complex geometries using ANSYS Meshing tools (Fluent Meshing, ICEM CFD, etc.)
  • Apply advanced meshing techniques, including:
  • Boundary layer meshing to accurately capture near-wall flow behavior and gradients.
  • Local mesh refinement in areas with high shear, complex geometry, or significant phase interactions.
  • Non-conformal meshing to efficiently connect different mesh types or resolutions across interfaces.
  • Perform mesh quality checks (skewness, orthogonality, aspect ratio) and conduct mesh sensitivity and independence studies to ensure numerical accuracy and robustness.
  • Configure and tune solver settings for various flow regimes, including laminar, turbulent, and multiphase flows
  • Analyse simulation results to extract insights into flow distribution, gas evolution, and transport phenomena.
  • Collaborate with cross-functional teams to integrate simulation findings into product design and optimization.
  • Document simulation methodologies, assumptions, and results for internal and external stakeholders.

Required Qualifications:

  • Bachelor's or Master's degree in Mechanical Engineering, Chemical Engineering, or a related field.
  • 1–2 years of hands-on experience with ANSYS CFD tools (Fluent, CFX), particularly in multiphase flow simulations.
  • Solid understanding of meshing techniques, with experience or exposure to:
  • Structured, unstructured, and hybrid meshing approaches.
  • Use of inflation layers, boundary layer control, and mesh adaptation.
  • Familiarity with mesh quality metrics such as skewness, orthogonality, and aspect ratio.
  • Good knowledge of solver settings and numerical schemes, including:
  • Basic understanding of pressure-velocity coupling schemes (e.g., SIMPLE, PISO, Coupled).
  • Awareness of discretization schemes (e.g., first-order, second-order upwind).
  • Exposure to steady and transient simulation setups.
  • Understanding of convergence criteria, residual monitoring, and under-relaxation factors.
  • Introductory experience with multiphase flow models and their applications.
  • Familiarity with common turbulence models (e.g., k-ε, k-ω SST) and their use cases.
  • Strong fundamentals in fluid dynamics and transport phenomena.
  • Interest or basic knowledge in electrochemical systems (e.g., electrolysis), with a willingness to learn and grow in this domain.

Preferred Qualifications:

  • Exposure to or hands-on experience with electrolyser or fuel cell modelling.
  • Basic understanding of electrochemical reaction kinetics, species transport, and gas-liquid interface behaviour.
  • Familiarity with Multiphysics simulations, especially involving fluid flow, electrochemistry, and heat transfer.
  • Experience or interest in using scripting tools like Python, MATLAB, or journal files to automate simulation workflows and post-processing.
  • Eagerness to learn and apply advanced simulation techniques in real-world electrochemical applications.

What We Offer:

  • Opportunity to work on transformative technologies in the clean energy and deep tech sectors.
  • A collaborative, innovation-driven environment.
  • Technical mentorship and career growth opportunities.
  • Competitive compensation and benefits.
