In this project, a twin screw extruder is simulated using ANSYS Fluent to analyze the interaction of water and particles within the system. The flow rate of particles is nine times that of the continuous phase, and both the interactions within the particle phase and with the continuous phase are considered using a 4-way DEM module. The geometry is designed in ANSYS SpaceClaim, and an unstructured mesh is generated in ANSYS Meshing with dynamic adjustments at each time step. The k-epsilon turbulence model and DPM model are employed along with the DEM module to simulate interactions. This complex simulation, involving dynamic meshing and high computational demands, reveals insights into particle tracking and residence time as the extruder operates at 300 rpm with a 60-degree rotation scope.

This project explores the simulation of phase change material (PCM) melting within a 2D cavity, utilizing internal fins and nanoparticles to enhance thermal performance. The cavity, measuring 20mm in width and filled with paraffin wax, features a left wall and fin maintained at a constant temperature of 350K, while the right wall is kept at 300K, with other walls insulated. Simulations conducted over 375 seconds revealed that heat transfer occurs due to a temperature gradient, initiating phase change once the PCM reaches its melting temperature. Results indicated that 35.65% of the material was melted by the end of the simulation, providing critical insights into heat transfer efficiency and the influence of design parameters on PCM behavior in thermal systems.
