The fluid mechanics of impingement mixing was investigated experimentally, and the design procedure, including scale‐up, for the MIT Liquid Injection Molding System was established. For impingement mixing to be effective, the Reynolds number based on the nozzle diameter must be greater than about 50 and the momentum ratio of the fluid components must he equal to 1 in addition to satisfying the desired mass flow rate ratio.
