In many of today's chemical applications, efficient mixing is critical to achieve product quality and uniformity, and ORNL engineers have devised a better way to do the mixing. The electrohydrodynamic micromixing reactor uses a specially designed electrified injection nozzle that mixes the chemicals instantly as they are introduced. When a high voltage is applied to the nozzle, the motion of charge carriers generates strong turbulent flows near the nozzle tip. In processes for producing ultrafine particles, the micromixing reactor allows for precise control of particle size, which allows for more control of the final product. This technology could lead to improved methods for the synthesis of advanced materials and to miniaturized processes.
