tryckslag
Tryckslag is a term used to describe a sudden transient change in pressure within a fluid- or gas-filled system. It denotes a pressure spike (positive) or a pressure drop (negative) that occurs when flow conditions change rapidly, such as by closing or opening a valve, starting or stopping a pump, or other abrupt boundary movements. In fluids, these events propagate as pressure waves, which can reflect at system boundaries and create complex transient pressure fields.
Causes of tryckslag include rapid valve actuation, pump trips, piston movements in hydraulic or pneumatic systems,
Measurement and effects: Tryckslag is monitored with pressure sensors and characterized by peak pressure and negative
Applications and mitigation: Engineers study tryckslag to prevent damage in hydraulic, pneumatic, and gas systems. Mitigation
