It was found that the experimental solutions with large elasticity agree with a model based on a single spring. To understand the reasons the bungee jet can be assumed a single spring, we investigated the velocity field and stress field. In particular, we used a polarization measurement which is new measurement technology to obtain the stress field. The result suggests there are two types of motion in the bungee jet: (1)extension velocity is uniform, and (2)stress is constant. Namely, our results indicate the jet velocity distribution based on the flow-focusing effect is quite important in the bungee jet behavior. Furthermore, we consider a damper in addition to a single spring to predict the bungee jet behavior even when small elasticity polymer solutions. As a result, the model considering a single spring as well as a damper can predict the bungee jet behavior in all elasticity.
