Fluids is open-source software for engineers and technicians working in the fields of chemical, mechanical, or civil engineering. It includes modules for piping, fittings, pumps, tanks, compressible flow, open-channel flow, atmospheric properties, solar properties, particle size distributions, two phase flow, friction factors, control valves, orifice plates and other flow meters, ejectors, relief valves, and more.
The fluids library is designed to be a low-overhead, lightweight repository of engineering knowledge and utilities that relate to fluid dynamics. It occupies ~4 MB of RAM on load and should load in a small fraction of a second.
Fluids was originally tightly integrated with SciPy and NumPy; today they are optional components used for only a small amount of functionality which do not have pure-Python numerical methods implemented. Fluids targets Python 2.7 and up as well as PyPy2 and PyPy3. Additionally, fluids has been tested by the author to load in IronPython, Jython, and micropython.
While the routines in Fluids are normally quite fast and as efficiently coded as possible, depending on the application there can still be a need for further speed. PyPy provides a substantial speed boost of 6-12 times for most methods. It is the author's preferred accelerator. Fluids also supports Numba, a powerful accelerator that works well with NumPy.
Fluids runs on all operating systems which support Python, is quick to install, and is free of charge. Fluids is designed to be easy to use while still providing powerful functionality. If you need to perform some fluid dynamics calculations, give fluids a try.
