Building a Setup to Investigate Reaction-Diffusion-Advection Systems

A mechanism was built to investigate the properties of chemical Reaction-Diffusion-Advection (RDA) systems. This mechanism is computer controlled and uses syringes to push, or advect, liquid at different rates. Five syringes of varying volumes, along with four different needle gauge sizes, were used to find flow rates of varying speeds. These flow rates were recorded in milliliters per second and micrometers per second with respect to where the flow was coming from or going to. The flow rates created by the mechanism were matched to theoretical flow rates and it was found that smaller syringes with smaller gauge sized needles more closely matched theoretical flow rates than larger needles and larger gauge sized needles. This mechanism has numerous experimental applications and can be used in conjunction with many ongoing RDA and hydrodynamic experiments.
