In the transient solutions of fiber spinning and film casting process dynamics accompanied by spinline flow-induced crystallization was investigated incorporating flow-induced crystallization kinetics into the mathematical model of the system and then devised proper numerical schemes to generate the temporal pictures of the system. It turns out that the difficulty obtaining the transient solutions of the processes accompanied by flow-induced crystallization lies in, among these, the extremely high sensitivity of the spinline velocity towards the fluid stress level. The transient solutions thus obtained will be used for developing optimal strategies to enhance the stability and productivity of the processes.
