Computational Fluid Dynamics (CFD)

Our team of qualified CFD engineers collaborate to deliver advanced solutions to our clients by giving them full support through both Conceptual and Detailed design phases.
We have successfully completed complex projects involving all the main CFD capabilities. Main areas in which we resort to CFD tools are:

  • Health, Safety & Environment. The use of computational fluid dynamics technique is applied to safety system with relevant advantages. CFD turns out to be a powerful tool, able to simulate complex scenarios defined by statistical studies on major accidents, otherwise impossible to reproduced with experiments in situation at high risk or simply to be evaluated with analytical approach. Typical applications in HSE area, studied by means of CFD, are:
    • Indoor-outdoor pollutant dispersion;
    • Risk analysis of heat source in industrial plant;
    • Gas storage and gas transport system behaviour.
  • System and Equipment Design & Optimization. CFD analysis are carried out in order to understand which are the actual condition of the flow, across a specified equipment during design phases. Simulations can predict how the flow behave and evaluate important aspects like pressure drops, velocity distribution, heat exchange and temperature field. Devices under analysis can be control valve, diffuser, manifold, heat exchanger and general fittings. Corresponding performance parameters can be assessed as well. Other CFD studies realized during design step, are applied to characterize the internal flow inside tanks or vessels. Optimization of the internal flow circulation according to the specified application, can be carried out by means of CFD simulations, able to evaluate the effect of baffles and jet mixing system. Multiphase interactions or phase change phenomena can be analysed as well. Finally, performance evaluation of rotating machinery as fan and pump, placed in a specific plant, can be model including intake and discharge lines. In this way, CFD can predict if the machinery is suitable or, on the other hand, if plant is not properly designed.

  • Cleanroom Design. Optimization of cleanroom in pharmaceutical and manufacturing application can be easily carried out with CFD analysis. Through the evaluation of the ventilation system and the modification of the room design, simulations can predict air change effectiveness, contaminant distribution and air flow speed efficiency.

Streamline Engineering is equipped with leading professional CFD software (ANSYS Fluent and Simscale) able to face a wide range of industrial problems and to win the competition by accelerating products Time to Market. Main simulation features treated are:

  • Steady and Transient Simulations;
  • Laminar and Turbulent Flows;
