Applied Flow Technology Arrow 2023 v10.0.1100

Applied Flow Technology Arrow - отличная программа для гидравлического расчета различных разветвленных сетей со сжимаемыми средами (включает также расчет теплопотерь). Осуществляет анализ системы при скоростях вплоть до звуковой (также включен анализ сети при звуковом ударе).

AFT Arrow is a fluid dynamic simulation tool used to calculate pressure drop and flow distribution in gas piping and ducting systems.

• Accurately simulate individual components and their interaction including effects of heat transfer, real gases and choked flow.
• Tightly integrate equipment characteristics, analysis and output with your system’s schematic representation.
• Utilize a wide array of features without sacrificing your need for a short learning curve.
• Compare the performance of new designs and assure all design requirements are met.
• Identify and correct operational problems in installed systems.
• Significantly improve the quality of systems engineering and produces less costly, more efficient and more reliable piping systems.

Applied Flow Technology Fathom 2023 v13.0.1100

Applied Flow Technology Fathom - программно-аналитический комплекс моделирования потока в трубопроводе. Удобный графический интерфейс, встроенная библиотека оборудования, арматуры и флюидов, широкие аналитические возможности, схематическое изображение создаваемого объекта, все это реализовано в AFT Fathom и предоставляет инженеру проектировщику возможность системного подхода в реализации проектов любой сложности. AFT Fathom обладает большим спектром возможностей не являясь при этом компромиссом между функциональностью и сложностью в освоении и использовании.

Features:

• Advanced hydraulic solver
• Detailed modeling for centrifugal and positive displacement pumps
• Scenario Manager to track all design variants and operational possibilities in a single model file
• Pump vs. system curve generation including individual head curves and composite efficiency
• Thermal analysis including piping heat transfer and heat exchanger modeling
• Supports Newtonian and non-Newtonian fluids, including non-settling slurries
• Optional ChempakTM add-on utility provides a thermophysical database of almost 700 fluids

AFT Fathom add-on modules:

• Settling Slurry (SSL) - models the effects of pumping fluids containing settling solids using the Wilson/GIW method
• Extended Time Simulation (XTS) - models dynamic system behavior
• Goal Seek and Control (GSC) - identifies input parameters that yield desired output values and simulates control functions
• Automated Sizing (APS and ANS) - automate the process of sizing pipelines and piping networks based on required conditions, such as maximum pressure or minimum flow, to reduce cost or weight
