Abstract The electrospinning process is a simple and versatile method for the fabrication of nanofibers. The low production rate of fibers in a conventional single-nozzle setup inhibits the commercialization of the process for large-scale applications. Multiple-nozzle electrospinning is a straightforward approach in the efforts of increasing fiber yield. The installation of multiple nozzles in a single setup alters the electric field in the working space, affecting the process and fiber quality. In this study, the effects of varying the distance between adjacent nozzles are investigated in terms of the jet behavior and fiber distribution, comparing between equally-spaced and unequally-spaced nozzles. The simulation of the electric field shows a more uniform electric field distribution near the nozzle tips for the unequally-spaced nozzles. The unequally-spaced setup also resulted in a more uniform distribution of fiber diameter and deposited fiber mats. Additionally, electrospinnability was also improved by using unequally-spaced nozzles.
