Understanding Pressure Transients in Fluid Systems

Pressure transients, often referred to as surges or water hammer, are rapid changes in fluid pressure and flow rate within a piping system. These events can be triggered by sudden changes in operational conditions, such as pump trips, valve operations, or pipe ruptures. Uncontrolled pressure transients can lead to significant equipment damage, system failures, and safety hazards. AFT Impulse models these phenomena by applying fundamental fluid dynamics principles and advanced numerical methods, allowing engineers to predict the magnitude and timing of pressure waves and implement protective measures.
