About NoPo

NoPo Nanotechnologies is India's only commercial manufacturer of Single Walled Carbon Nanotubes (SWCNTs), produced through our proprietary HiPCO (High Pressure Carbon Monoxide) process. We are a fast growing, technically driven organization working at the frontier of advanced materials manufacturing, with applications spanning energy, composites, and next generation industrial technologies.

Key Responsibilities

A. CFD Modelling and Simulation

Develop and execute CFD models for tubular reactors, multi-tubular reactors, gas flow systems, and high-temperature process equipment used in SWCNT production.
Simulate fluid flow, Reynolds number / turbulence, temperature distribution, heat transfer, pressure drop, and gas residence time under different operating conditions.
Select appropriate turbulence models, discretization schemes, boundary conditions, and numerical solution methods based on the physics of the process.
Conduct mesh generation, mesh independence studies, convergence assessment, and numerical sensitivity analysis.

B. Reactor Design and Thermal Analysis

Analyse temperature uniformity, hot spots, cold zones, and thermal gradients within reactors and associated heating systems.
Evaluate heat transfer between heating elements, reactor walls, and process gases.
Investigate the impact of reactor geometry, tube arrangement, heating configuration, insulation, and operating conditions on thermal performance.

C. SWCNT Process and Reactor Optimization and troubleshooting

Model gas flow and residence time for CO-based SWCNT production processes, including HiPco or other relevant processes, as applicable to the company's technology.
Evaluate gas distribution, mixing, recirculation, flow maldistribution, and pressure drop across reactor assemblies.
Support the modelling of gas-phase reactions, species transport, and reaction kinetics where suitable kinetic data are available.

Assess the effect of operating parameters on process stability, gas utilization, thermal efficiency, and potential reactor fouling.
Collaborate with experimental teams to develop modelling approaches for complex R&D problems.

D. Validation, Troubleshooting, and Continuous Improvement

Validate CFD predictions against experimental measurements, pilot plant data, temperature profiles, pressure measurements, and flow data.
Investigate deviations between simulated and actual reactor performance and recommend corrective actions.
Conduct parametric studies, sensitivity analysis, and design-of-experiments-based simulation studies.
Provide engineering recommendations to resolve flow maldistribution, overheating, inadequate heat transfer, and pressure-drop issues.
Support root cause analysis of reactor performance and equipment-related problems.

Requirements

Bachelor's degree in Mechanical Engineering, Chemical Engineering, Aerospace Engineering, or a closely related engineering discipline.
3–5 years of hands-on experience in CFD modelling and simulation for industrial equipment, reactors, thermal systems, or chemical processes.
Proficiency in at least one major CFD platform, such as ANSYS Fluent, ANSYS CFX, or OpenFOAM.
Strong understanding of fluid mechanics, heat transfer, thermodynamics, and numerical methods.
Practical experience with turbulence modelling, mesh generation, mesh quality assessment, convergence monitoring, and mesh independence studies.
Working knowledge of energy equations, species transport, pressure-drop calculations, and residence-time analysis.
Ability to define appropriate boundary conditions and material properties and critically assess simulation assumptions.
Experience in interpreting CFD results and translating them into practical engineering recommendations.
Strong analytical, problem-solving, technical documentation, and communication skills.

Preferred Skills

Experience in CFD simulation of chemical reactors, tubular reactors, multi-tubular reactors, or high-temperature gas-phase processes.
Exposure to carbon nanotube synthesis, CVD, HiPco, gas-phase nanomaterial synthesis, or related advanced-materials processes.
Experience with conjugate heat transfer (CHT), radiation modelling, and high-temperature thermal systems.
Understanding of reacting-flow models, finite-rate chemistry, species transport, and chemical kinetics.
Exposure to particle tracking, aerosol dynamics, nucleation, deposition, or population balance modelling.
Experience in modelling electrical heating systems, heated reactor assemblies, refractory insulation, and thermal losses.
Knowledge of statistical analysis, design of experiments (DoE), and correlation of simulation results with experimental data.
Experience supporting pilot-scale equipment design, process troubleshooting, and technology scale-up.
