Simulated melt conveying characteristics for two-dimensional (undercut) curved channels

Excel file containing numerical simulation results for the dimensionless flow rate, dimensionless dissipation rate, and the dimensionless average shear rate in confined, curved screw channels without flight effect. These results serve to correct the data for the three-dimensional case [1] to account for flight undercuts (i.e., the screw flight does not extend over the entire channel depth), which is done by weighted averaging. Modification compared to the previous version:The dimensionless average shear rate is now included as additional target variable.
