Problem 1: An extruder used to melt PET, the inlet of the extruder is hopper, and it relates to the feed zone. The feed zone has the temperature of 25 C, and the temperature at metering zone is 260 C. The total length of the extruder is about 1.5 m. The melt velocity is due to the movement of screw, and it is about 2.5 m's and the density 138 gm/cm?. The melt must be filter via filter press located at the end of metering section. This filter press is blocked due to deposition of unwanted particles, and it cause to create backflow and the backflow velocity assume to be 0.6 m/s. a) Identify the computational domain and divide into 5 nodal points b) Generate discretization equation using negative upwind scheme on backflow c) Generate discretization equation using positive upwind scheme on forward flow heaters SCOOT pingat ho cerew wote past are Problem 1: An extruder used to melt PET, the inlet of the extruder is hopper, and it relates to the feed zone.
