✦ Synopsis

The static pressure distributions on four cylinders arranged in a square configuration subject to cross flow are presented for spacing ratios ranging from 1.26 to 5.80 and angles of incidence of the oncoming flow ranging from 0 to (45^{\circ}) in (15^{\circ}) intervals. The corresponding forces, lift and drag, on each cylinder are also given by integration from the measured pressure distributions. The results are compared with flow visualizations and with other measurements. A critical spacing ratio which was different from the situation of two and three cylinders, was found to be (L / D=2.7) at small stagger angles. The effect of the angle of incidence on the force and base pressure coefficients is also discussed.

## Abstract The self‐interference flow (SIF) of a melt in a cavity during injection molding is introduced. It comes from two streams of the melt being split by a patented mold gate called a twin gate. The effects of this flow on the static and dynamic mechanical properties, thickness distribution,
