Abstract The results of experimental study of pressure variations inside core box during resin bonded sand filling process are reported. The test core specimens were produced using Laempe® Test Specimen Curing Machine L 1. A special pressure measurement system was designed and built with safety and portability requirements of the foundry environment. Special experiments were conducted to establish the effect of sand deposition on vent permeability.

Experiment of aluminum block erosion using organ-pipe nozzle was carried out in air. The erosion effects of water jet were used to evaluate the performance of organ-pipe nozzle. The experiment and corresponding data were used to analyze the effects of nozzle configuration, jet pressure, standoff distance. Results have shown that the organ-pipe water jets are much more effective in aluminum block erosion.

An experimental study was performed to investigate the local characteristics of heat transfer from vertical simulated micro-chips to impinging submerged circular water jets. The effects of jet velocity, and nozzle-to-plate spacing were studied in the range of Re = 5.0 × 103 ˜ 3.6 × 104. Heat transfer rates at the stagnation point and local heat transfer distributions were correlated. Transition from laminar to turbulent flow was observed.
