Calculators & Formulas

Flow inside a microfluidic channel is governed by the pressure difference at its extremities. Instead of using the traditional Hagen-Poiseuille equation, FLUI’DEVICE employs the Darcy-Weisbach equation. This approach combines the friction-induced pressure drop of a straight channel with the local turbulence resulting from the channel geometry.

With :

λ the Moody friction factorλ = f(R_e , _k) withR_e the Reynolds Number andk a constant describing the channel wall surface roughness.
ξ_loc the local turbulence coefficient with the power of computational fluid dynamics and 50 years of experiments.
D_h andL the channel characteristic dimension and length, respectively.
ρ the fluid viscosity andv the flow mean velocity.

Moody Friction Factor in a pipe : λ describes different flow regime.
In laminar flow (R_e < 2300), λ = 64 / R_e is independant of the surface roughness.
In turbulent flow (R_e > 4000) λ, is predominetly determined by the cross-sectional shape of the pipe and the surface roughness.

What is a microfluidic calculator?

A microfluidic calculator is a specialized tool that helps with microfluidic chip design, microfluidic valve design, and overall microfluidic channel design. It uses established equations to calculate pressure and flow distribution within these miniaturized fluid handling systems. This is particularly useful for designs operating at low Reynolds numbers, where smooth, laminar flow is desired and turbulence is minimal.

How does FLUI'DEVICE differ from other calculators?

FLUI'DEVICE is a comprehensive online platform dedicated to your microfluidic design needs. It boasts a continuously growing library of microfluidic geometries, allowing you to tackle complex designs with ease. Unlike other online calculators limited to simple geometries, FLUI'DEVICE empowers you to perform hydrodynamics calculations on intricate designs.

How accurate is FLUI'DEVICE?

FLUI'DEVICE supports design precision down to 1 micron, which is sufficient for most microfluidic applications. For 3D export and fabrication, you can be confident in its exceptional accuracy , reaching a staggering 0.0001 micron for position and dimension. The flow calculator's accuracy naturally varies based on the Reynolds Number and the complexity of your system. However, the FLUI'DEVICE team is constantly working to improve its capabilities, ensuring reliable results for your microfluidic channel design.

What are the limitations of FLUI'DEVICE?

While FLUI'DEVICEe offers advanced functionalities similar to Computational Fluid Dynamics (CFD) software, it doesn't utilize the finite element method employed by more sophisticated programs. Instead, it assigns specific microfluidic behaviors to each block within its library. This approach delivers reliable results but may not provide highly localized, point-specific information within the device. Additionally, FLUI'DEVICE currently focuses on hydrodynamic calculations, primarily providing flow rate and pressure data. However, there are rumors of upcoming features that could expand its functionalities.

Can I import my designs into FLUI'DEVICE?

Currently, FLUI'DEVICE relies on its library of blocks to generate designs and doesn't support the import of 2D or 3D files from external software.

Can I export my design to other software?

Absolutely! FLUI'DEVICE allows you to export your designs in two formats:

2D .SVG files: Compatible with most graphic software, allowing for further editing after export. 3D .STL files: Usable in various CAD, CFD, and CAM software for seamless integration with your preferred design workflow. However, be aware that some CAD applications might encounter compatibility issues with .STL files.

What features does FLUI'DEVICE offer to help with microfluidic design?

FLUI'DEVICE offers a suite of features designed to streamline your microfluidic design process, including:
Flow rate calculator: Calculate the flow rate within your microfluidic design.
Reynolds number calculator: Determine the Reynolds number to assess the flow regime (laminar vs. turbulent).
Pressure drop calculator: Estimate pressure drop across your microfluidic channels.
