The low inertial forces present within many microfluidic setups often yield low Reynolds number flows: | The low inertial forces present within many microfluidic setups often yield low Reynolds number flows <sup>[5]</sup> : low levels of turbulence can also be expected in these flow regimes. Thus convection is not prevalent in microfluidic setups, unless they are purposely induced | ||
Low length and velocity scales in microfluidic setups- > Low Reynolds number. This also implies lower convective forces when compared to larger devices. As such, Pe in a microfluidic device is usually lower than 1 and as such, implying that these regimes are diffusion dominant[Squires and Quake] | Low length and velocity scales in microfluidic setups- > Low Reynolds number.
