AB - Herein, polyvinyl alcohol nanofibrous membrane was fabricated firstly by the  high-curvature solid-needle electrospinning. The influence of electrode  curvature (needle angle), spinning voltage, solution concentration and  collector distance on nanofiber morphology was systematically investigated  numerically and experimentally. Numerical simulation shows that the  electrical field increases with the increase of spinning voltage, while  decreases with the increase of needle angle and collector distance. The  experimental results are consistent with the numerical results.  Furthermore, the solution concentration can be used to adjust the diameter  of polyvinyl alcohol nanofibers. The possible applications of the nanofiber  membrane to energy generation, water treatment, and separation are also  discussed.
