For incompressible hydraulic analysis, an easy way to quantify basic to advanced modeling is the presence and scope of heat transfer. Basic models are isothermal, where the temperature of the working fluid doesn't change. This makes calculations simpler as the density won't be altered. The intermediate level would be to introduce heat transfer to a...
The Settling Slurry Module (SSL) for AFT Fathom and AFT Impulse has long been used to model complex systems with settling slurries in a range of industries. Previously all slurry models were variations of the Wilson, Addie, Clift method requiring differing levels of user input to use. The release of AFT Fathom 13 and AFT Impulse 10 has brought with...
Classically, hydraulic loss tends to be categorized as major losses, which are due to friction between the fluid and the pipe's inner surface, and minor losses, which are due to entrances, exits, fittings, and other component effects. Losses due to friction tend to have a greater impact on the hydraulic resistance and this could be the main reason ...
AFT introduced the Design Alert Manager in 2015 and it has proven to be a highly valuable tool to better organize Design Alerts within AFT model files. With the 2023 releases of all AFT products, the Design Alert Manager has been reorganized to improve the process of creating and applying user-defined alerts. It is now much...
Much can be done to reduce model run times, but it's a fact of life with transient simulations that some systems are just large and complex, need to cover longer spans of time, or have dynamics that can only be accurately captured with finer sectioning. In such cases, long run times can be unavoidable. Have you ever needed to pause a lengthy s...
The Annotation Tool has new shapes and customization options which will help you organize, markup, comment, and effectively present your models when using the new versions of Fathom 13, Arrow 10, Impulse 10, and xStream 3. In addition to the pre-existing rectangles and ellipses, you can now add diamonds, pentagons, hexagons, octagons, clouds, trian...
The release of AFT xStream 3 brings with it reciprocating compressors for your gas transient models! Positive displacement compressors now have two subtypes: fixed flow rate for a steady mass or volumetric flow rate, as was present previously, and the all-new reciprocating compressor option. The reciprocating compressor model is for compressors in ...
