Figures

Grahic Jump Location
(a) The gate at x=0 is switched on as soon as the flow reaches it. (b) The gate at x=0 is switched on after the flow reaches x=0.3W, where W is the width of the mold. (c) The gate at x=0 is switched on after the flow reaches x=0.6W. In all cases, the flow proceeds from left to right from a line injection source on the left under constant flow rate until the gate is switched on.
