We present a simple analytical model for the forces that determine jet diameter during electrospinning as a function of surface tension, flow rate, and electric current in the jet. The model predicts the existence of a terminal jet diameter, beyond which further thinning of the jet due to growth of the whipping instability does not occur. Experimental data for various electrospun fibers attest to the accuracy of the model.
我们提出了一个简单的分析模型，用于描述在静电纺丝过程中决定射流直径的力，该力是射流表面张力、流速和电流的函数。该模型预测存在一个终端射流直径，超过此直径，由于摆动不稳定性的增长，射流不会进一步变细。各种电纺纤维的实验数据证明了该模型的准确性。
