The essential target of this examination is to compare the thermal properties of two different polyamide composite blends with inventive thermal properties. The two combination of specimen was prepared by using polyamide-6 (PA6) reinforced with 10, 20 and 30 wt% glass fiber (GF) and glass beads (GB) respectively and these composite blends were extruded in form of wire through twin screw extrusion process. The experimental study illustrates to print the specimens by means of a commercial FDM three dimensional (3D) printer. The measure the responses like morphology, thermal conductivity and heat distortion temperature of composites was observed. The results associate that SEM morphology shows high dense homogeneous distribution and fine arrangement of particles in the printed samples. Moreover it reveals that increasing thermal properties of the printed specimen like TC and HDT with the enhancement of 30% glass fiber and bead content in PA6 composites than lower weight percentage composites. The glass fibers are highly crystalline material that can even improve the thermal properties of the polymer matrix and the glass beads are dimensionally stable…

Shear Assisted Processing and Extrusion

Published 2019-07-01 by Tech Briefs Media Group in United States

Shear Assisted Processing and Extrusion (ShAPE™) allows creation of wire, bar, and tubular extrusions that show significant improvement in material properties; for example, magnesium extrusions have been manufactured with unprecedented ductility (how far the material can stretch before it breaks) and energy absorption (how much energy can be absorbed during compression of a tubular extrusion) over conventional methods.

Lattice Boltzmann Simulations of Flow Over an Iced Airfoil

Dassault Systemes-Rafael Ihi, Andre Ribeiro
Embraer-Luis Santos, Daniel Silva
Published 2019-06-10 by SAE International in United States
This paper presents an aerodynamic degradation study of an iced airfoil, using the Lattice Boltzmann approach with the commercial software PowerFLOW. Three-dimensional numerical simulations were performed with an extruded constant section of the GLC-305 airfoil with a leading-edge double-horn ice shape using periodic boundary conditions. The freestream Reynolds number, based on the chord, is 3.5 million and the Mach number is 0.12. An extensive comparison of the main flow features with experimental data is performed, including aerodynamic coefficients, pressure coefficient distributions, velocity and turbulence contours along with its profiles at several positions, and stagnation streamlines. The drag coefficient agrees well with experiments, in spite of a small shift. Two different wind tunnel measurements, using different measurement techniques, were compared to the CFD results, which mostly stayed in between the experimental data. Velocity and turbulence intensity contours as well as stagnation streamlines enabled a more detailed comparison of the flow field, which showed great accuracy of the simulations to predict the reattachment location. Overall, very good agreement is obtained with the available reference data. The numerical…
