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.
