3D Finite Elements Simulation of the Single Screw Extruder with Rotational Barrel Segment
Gajdoš, Ivan; Sikora, Janusz; Dulebová, Ľudmila; Varga, Ján (2019-09)This paper aims to numerically evaluate a new concept of construction in a single screw extruder design. Rotational barrel segment introduced in 1998 significantly changes the kinematics of movement in a single screw ... -
CFD Simulation of Rotational Barrel Segment Mixing Performance in Single Screw Extruder
Gajdoš, Ivan; Slota, Jan; Sikora, Janusz; Krasinskyi, Volodymyr (Растр-7, 2019-11)Introducing a new element rotational barrel segment (RBS) into construction of single screw extruder (SSE), significantly changes the kinematic of motion in SSE. Main goal of incorporating RBS into SSE construction is ... -
Numerical Evaluation of Distributive Mixing Capability of Single Screw Extruder With Rotational Barrel Segment
Gajdoš, Ivan; Greškovič, František; Dulebová, Ľudmila; Sikora, Janusz (Rzeszów University of Technology, 2020-10-21)Since their massive expansion in the first half of 20th century, extruders have undergone a continuous development, especially in plastic industry. The need to shorten time of developing new products and increase the ... -
Polyethylene-Matrix Composites with Halloysite Nanotubes with Enhanced Physical/Thermal Properties
Sikora, Janusz; Gajdoš, Ivan; Puszka, Andrzej (MDPI, Basel, Switzerland, 2019-05-02)The aim of the present work is to investigate the e ect of halloysite nanotubes (HNT) on the mechanical properties of low-density polyethylene composites modified by maleic anhydride-grafted PE (PE-graft-MA). Polyethylene ... -
Utilization of Mesh Superposition Technique for Simulation of Single Screw Extruder
Gajdoš, Ivan; Spišák, Emil; Sikora, Janusz; Krasinskyi, Volodymyr (Technical University of Kosice, 2019-09-15)As the technology of polymer extrusion becomes more sophisticated, demand on possibility to accurate simulate extrusion process in full 3D rises significant. The single screw extruder (SSE) is one of the most widely used ...
