This work deals with the modelling and simulation of a degassing process mainly used for extruders in polymer industry. The numerical simulations are done with finite‐volume method using OpenFOAM for a 2D single screw extruder. The material parameters have been all chosen for a PDMS‐Pentane polymer mixture so that the results could be compared with the available experiments already performed for this mixture [1]. In addition to experiments, the numerical results will be compared with an analytical solution derived from Danckwerts' model [2][3]. (© 2014 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim)
