Key Features

Advanced Simulation Capabilities

AFT Impulse offers sophisticated fluid dynamic simulation, allowing users to accurately calculate pressure transients in various piping systems. From waterhammer effects to surge analysis, it covers a wide range of scenarios including liquid systems with water, petroleum, chemicals, and more.

Dynamic System Adjustment

Users can experiment with different operating conditions and scenarios effortlessly. The software enables easy manipulation of system input data such as valve positions, pump operations, pressures, temperatures, and more, allowing for comprehensive analysis and optimization.

Comprehensive Component Modeling

AFT Impulse supports modeling of a diverse range of system components sourced from empirical handbooks or manufacturer data. This includes pumps, valves, relief valves, surge tanks, and gas accumulators, ensuring accurate representation of real-world systems.

Safety and Reliability Enhancement

By identifying and addressing potential issues like water hammer and transient pressures, AFT Impulse helps in designing and operating systems with greater safety and reliability. It facilitates proper sizing and locating of surge equipment to prevent damaging effects and validate safety features.

Scenario Management and Visualization

The Scenario Manager allows users to track different design variants and operational possibilities within a single model file. Additionally, animation tools provide visual interpretation of complex transient interactions, enhancing understanding and decision-making.

Seamless Integration and Data Exchange

AFT Impulse supports robust data integration by allowing import and export of piping layouts and dimensional data from various sources such as GIS Shapefiles, CAESAR II® Neutral Files, and PCF files. Excel integration further streamlines data import and export processes, ensuring efficient workflow and compatibility with existing systems.

Settling Slurry (SSL)

The only commercial software solution that can model both non-settling and settling slurry water hammer effects.

Pulsation Frequency Analysis (PFA)

Helps identify pipe acoustical frequencies to avoid resonance from excitation, especially in systems with positive displacement pumps
