Junior ANSYS Engineer Electrochemistry (Electrolysis Focus)

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.

Role & 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.

Preferred candidate profile

Required Qualifications:

• Bachelors or Masters degree in Mechanical Engineering, Chemical Engineering, or a related field.
• 12 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-, k- 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.
