Advanced Engineering Simulation

The Advanced Engineering Simulation (AES) team at NXT focuses on delivering solutions to its mining and metals clients. A thorough understanding of first principle physics and chemistry based models is required to develop robust solutions. Practical experience, analytical skills, physical modelling skills plus world class analysis tools such as Computational Fluid Flow and Heat Transfer (CFD), Finite Element Modelling (FEM), Computational Thermodynamics are widely used by our team.

Our team gets involved in all aspects of project development from concept to operations including process design, scale up, implementation, start up and further into operational assistance. The AES team consists of experts with years of valuable experience in engineering simulation. Our services are focused on three major areas.

• Chemical Reactions Engineering and Modelling
• Computational Fluid Dynamics and Heat Transfer
• Finite Element Modelling and Computer Aided Engineering

Chemical Reactions Engineering and Modelling

Chemical Reactions Engineering and Modelling is applied to simulate real life metallurgical and chemical processes and this helps in performing "what if" and "root cause" analysis to test different scenarios and to find solutions to complicated problems.These models are often fine tuned against industrial data and thus makes them robust and pragmatic. Typical processes that are simulated by chemical reactions engineering and modelling are:

• Hydrometallurgical processes
• Pyrometallurgical processes
• Iron and steel processes
• Complex chemical reactions in chemical processes

Computational Fluid Dynamics and Heat Transfer

Computational Fluid Dynamics and Heat Transfer is applied to model complex multiphase turbulent flows occurring in mining and metallurgical processes. These include metallurgical reactors like Flotation Cells, Rotary Kilns, Electric Arc Furnaces, Oxygen Converters, Fume Handling and Ventilation systems, Metal casting systems, Cooling Towers, Smoke stacks and many more. The typical type of problems tackled by Computational Fluid Dynamics and Heat Transfer are:

• three phase flows
• particulate flows
• combustion
• turbulent flows
• heat transfer

Finite Element Modelling & Computer Aided Engineering

Most of the FEM models are applied for process design, process scale up, and failure analysis. In addition, NXT also uses Computer Aided Engineering tools for coupling various physics to simulate complex real life engineering problems.
