In this blog, we dive further into pump and system curves for complex systems. The examples include demonstrating system curves changing over time and when multiple system curves exist for a single system with multiple pumps in different locations of the system. Let us re-visit the multi-branched system example from the previo...
AFT Fathom XTS and AFT Impulse have long been able to start events like pump trips or valve closures when a certain condition is met in the system. For example, a valve can close when a tank is full, or a pump can trip when the flow is too low. However, complex systems often have multiple conditions that can cause an event. The pump may trip when the flow is too low OR the suction pressure is too low. The valve may only close when two tanks are full. AFT Fathom version 10 and AFT Impulse version 7 enhance the transient capabilities to allow the definition of these complex Multi-Condition Events.
