Flownex Simulation Environment

Midvaal Water Company approached M-Tech Industrial with the need to optimize their existing reticulation network. Their intention was to not only use the thermal-hydraulic model of the water reticulation network as a cost effective solution to their immediate problem areas, but also as a basis model for pump scheduling and possible future integration with their plant control system. A user friendly human machine interface allowed operators and engineers to use the high fidelity model of their reticulation system with minimal amounts of training.

This Case Study describes how Steinmüller was able to do what-if studies and to make decisions such as whether to remove the evaporative platens to optimize the plant in terms of reliability, plant availability and overall plant efficiency. Flownex proved valuable in the investigation by providing the new flow distribution in the water walls and super heaters based on design changes and also the steam condition that is provided to the turbines.

This case study demonstrates the steady-state simulation of the fresh water (drinking water) reticulation system in a small village.

This case study demonstrates the steady-state simulation of a compressed air network used in the mining industry.

This case study demonstrates the capability of Flownex to determine the orifice sizes required to ensure balanced flow in several parallel pipes connected by two headers. In practice this system coud represent the cooling flow through a simple radiator.

This case study demonstrates the capability of Flownex to balance air distribution systems by determining the orifice sizes or damper opening to ensure required flow at certain points in the system. In particular, this example demonstrates the balancing of central air conditioning distribution system. All the rooms that need to be supplied are similar and a mass flow of 0.02kg/s are required in each.

This case study demonstrates the control of a three stage chiller plant that cools water in a primary loop, which feeds into a secondary loop with a heat load.

This case study demonstrates the steady-state simulation of a High Temperature Gas-Cooled Reactor (HTGR) nuclear power plant (NPP).
