Intermittent

What are intermittent processes? Intermittent - (lat.) Intermittentibus intermittent, interrupted; intermittere to hold back, to be distracted. The reaction is intermittent - interrupted.

Continuous process refers to a process that continues over time and without periodic stops. However, there is also an alternative type of process with a characteristic cycle or periodic stop. A process in which there is a significant duration between successive stops is usually called “intermittent”. A periodic process is characterized by a sequence of operating periods and stopping periods. In a cyclic process, the stop following each working phase becomes identical to the first initial one. The duration of operating phases can vary significantly between different phases of the operating cycle. If the duration of the operating periods is the same for all phases, then the operating cycle is called isodiaphonic (symmetrical). For such periodic operation there is no concept of a time regime, since the phase intervals are equal in duration.

"Intermittance" is of great importance for a wide range of physical phenomena. It determines the nature of the operation of any power unit and covers almost all aspects of controlled modes, such as a gas generator and a gas turbine engine. In principle, when the power unit is turned on, three main periods of the regime can be distinguished - steady-state mode, transient mode and destruction mode. So, until the onset of the transition regime, the regime continues to remain an intermittent process. Intermittent mode occurs when such objects operate in a stationary mode due to a decrease in the reliability of individual components and a violation of their adjustment, however, within the framework of the general mode (steady state) fluctuations in pressure, cooling flow
