Скачать или смотреть Pressure Calculator for the pressure-driven flow control in Microfluidics

While using the pressure-driven flow control in Microfluidics, sometimes it is necessary to determine the required pressure based on the flow rate. The calculation is derived from the Navier-Stokes equation. Different microchannel geometries, i.e. rechtangular and cylindrical channels, effect the way how you calculate the pressure. While the calculation for the cylindrical channel is considered to be exact, there is no exact analytical formula for rectangular channels. Therefore an approximation is used.

For a near quadratic channel one can use the Huebscher formula. But for Microfluidics flat channels are typical, e.i. channels with larger aspect ratios, where the Huebscher formula is not appropriate. In our calculator we use our approximation based on Navier-Stokes equation.

On request we will provide our Python script and GUI written in tkinter. You can adjust both as you need.

Your feedback and suggestions will be very appreciated.
