Junior ANSYS CFD Engineer (Electrolysis Focus)

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.
