Liquid droplets are deformed when subjected to an electric field and acquires stable shapes. These shapes are a result of force balance between surface tension force, viscous force and electrostatic force. The droplet shape is turned into a conical shape, which is well known by 2Taylor cone3 with a half angle of 49.3o; then a fine jet comes from the cone apex. This phenomenon is widely studied and is strongly related to the electrospinning process which is recognized as an efficient technique to produce nanofibers. Variety of materials is used for electrospinning; most of them are polymers, composites, semiconductors or ceramics. Most of electrospinning experiments were done in research laboratories. The main objective of the research is to simulate the Taylor cone formation and jetting process as a part of electrospinning process using COMSOL® Multiphysics program. Three materials are used in this simulation; glycerol, distilled water and NaCl solution
