The effects of hole length-to-diameter ratio and compound angle on flat plate film cooling effectiveness are investigated from an experimental and numerical view. Film cooling effectiveness measurements are performed for seven blowing ratios (M) ranging from 0.3 to 2, five-hole length-to-diameter ratios (L/D) from 0.5 to 5, and two compound angles (β ...

AbstractA twin‐screw extruder with an ultra‐large length‐to‐diameter (L/D) ratio of 136 was developed and applied in the gel‐spinning process of ultra‐high molecular weight polyethylene (UHMWPE). UHMWPE gel fibers with concentrations of 6–18 wt% were produced at barrel temperatures of 150–180°C and screw speeds of 10–40 rpm.
