602 数値シミュレーションによる多層フィルムの溶融押出プロセスの粘弾性流動解析(2)(OS6-1 非ニュートン流体の流動現象,OS6 非ニュートン流体の流動現象,オーガナイズドセッション)
詳細
In the melt extrusion process of multi-layer films, interfacial instabilities occurs depending on various parameters which are the difference of rheological properties, thicknesses, or flow rates of each polymer layer and/or the die design. These instabilities cause defective moldings in manufacturing process. We performed viscoelastic flow simulations for multi-layer films and investigated the effect of various parameters on flow fields.
