https://github.com/calebbell/fluidsA lightweight, open-source Python library providing engineering utilities for fluid dynamics, serving as the fluid dynamics component of the Chemical Engineering Design Library (ChEDL). Version 1.3.1 includes modules for piping, pumps, tanks, and atmospheric properties, with specific functionality for calculating Darcy friction factors, Reynolds numbers, and pressure drops using Crane TP 410 methods. It provides datasets for pipe schedules, material roughness, and ASTM E11-17 and ISO 3310-1:2016 sieve sizes.
Fluids is a lightweight, low-overhead engineering library for fluid dynamics. It is designed for chemical, mechanical, and civil engineers and includes modules for:
fluids.pump module provides tools for sizing pumps, motors, and variable speed drives (VSDs) based on fluid dynamics requirements. It is designed to help engineers determine the appropriate hardware specifications for a given fluid system.fluids.geometry module provides tools for calculating the volume and surface area of various geometric shapes used in tank and heat exchanger design. This module is intended for engineering calculations involving fluid containment and thermal exchange surfaces.fluids.piping module provides implementations of various pipe schedules based on industry standards, including B36.10M-2004 (Carbon Steel), B36-19M-2004 (Stainless Steel), and various plastic pipe schedules. This allows users to retrieve physical dimensions (like inner diameter and wall thickness) for specific pipe types and schedules.fluids.packed_tower module provides functions to calculate the pressure drop across packed towers or demister pads. It also includes functionality for calculating flooding limits in these systems.The fluids.fittings module provides tools to calculate loss coefficients ($K$-factors) for various fluid system components. This includes standard geometries like entrances, exits, bends, contractions, expansions, tees, and valves, as well as comprehensive sets of fittings defined by the Hooper 2K and Darby 3K methods.
Use this module when you need to determine the pressure drop across specific fittings in a piping system based on their geometry and flow characteristics.
fluids.filters module provides functions to calculate the loss coefficient of a screen or grill within a pipe. These correlations are intended for use in hydraulic network design or simple fluid system modeling.The fluids.friction module provides a rigorous set of friction factor correlations for fluid dynamics. It includes implementations for common models such as:
Use this module to determine friction factors based on pipe roughness and other fluid properties.
The fluids.flow_meter module provides a rigorous set of correlations and solvers for working with various types of flow meters. This includes support for:
fluids.control_valve module provides tools for rating and sizing control valves. It supports calculating flow coefficients such as Cv, Kv, and Av, and implements standards including IEC 60534-8-4 (2015) and IEC 60534-8-3 (2011).The fluids.core module provides functions to calculate various dimensionless numbers used in fluid mechanics and heat transfer. This includes:
Refer to the fluids.core API documentation for specific function signatures and required input parameters (such as velocity, viscosity, characteristic length, etc.) for each calculation.
fluids.drag module provides tools to calculate the drag coefficient ($C_d$) of moving particles and determine their terminal velocity. It includes various published drag coefficient models and a numerical integrator to simulate the position of a sphere over time.
