Abstract

Theoretical as well as experimental work are conducted to increase our understanding on the behavior of HEAT TRANSFER and deformation taking place in film blowing of the extrusion process. The film blowing process was simulated by solving the force balance and energy equations established for the blown film moving in upward direction. Low-density polyethylene was employed for carrying out non-isothermal work and some operational parameters were measured. Four non-linear complex differential equations resulted from the balance and the energy equations were solved numerically, using the fifth-order Runge-Kutta method. In this method, considering the effect of gravity on the elevating film made the calculations more precise and reliable. The good agreement, observed between the simulation and experimental results, is a credit to the applicability of the established model in industrial scale. The established mathematical model predicts the bubble shape, temperature profile and film thickness as a function of the distance along the machine axis.
