Fluid Flow Systems
Transient cases
All the phenomena detailed so far (pressurised hydraulic modelling, open channel flows, description of compressible fluids and modelling of heating systems) have been investigated in a steady-state condition. This chapter provides a brief insight into why the initial conditions and transient operating states must be addressed. Transient cases are, for example, the start/stop of a pump or the sudden closing of a gate valve in HS. These can happen intentionally (due to operation) or due to an unexpected event (power failure, malfunction). Several literature sources provide further information, such as [1], [25], [26].
