Simulation modelling of systems and processes

Our models of industrial installations are prepared based on physical, probabilistic and hybrid methods. Within physical modelling we use both commercial (e.g. Thermoflex by Thermoflow Inc.) and our in-house (e.g. based on EES platform) software. The physical models usually include substance and energy balances, mathematical representation of different phenomena (like of thermodynamic, chemistry, heat transfer and fluid mechanics nature), as well, devices’ performance maps and other necessary data and assumptions. The probabilistic models are usually based on regressive methods or neural networks and use measurement data which are available in Customer’s archives.
Prepared simulation model may be then used for:

  • calculation of installation parameters in design state or in off-design conditions – may be applied for existing or planned facilities,
  • analysis of ugrading, extension or modification of installations,
  • detection of abnormal states of operation,
  • investigation of causes of failures,
  • other purposes in accordance with Customer’s expectations.

We also create automated calculation programs that are then used autonomously by our Customers.
