• Description:
  Results are presented of a study on center push/pull ventilation for open surface tanks. The objectives of the study were: to find the match points for the push and pull parts of the system; to develop the velocity profiles at one match point for the push only, the pull only, and the combination of the two; to characterize the general airflow patterns of the system. The study was performed on a center push/pull system that was installed on a simulated 8 foot wide open surface tank. The respective methods used for the objective of the study were as follows: visual observation of smoke inserted at the push blower inlet; smoke tube traces and velocity measurements with a hotwire anemometer; and smoke tube traces. The push/pull system appeared to work by two mechanisms: the exhaust captures the jet as it climbs the face of the hood; and the control of contaminants was aided by the entraining of ambient air by the jet. The author concludes that center push/pull can offer another option to designers for controlling emissions from plating tanks. While some understanding is presented of center push/pull, additional research is needed before a totally usable knowledge is available. Center push/pull as well as side push/pull are considered to be options worth considering for future research and design. [Description provided by NIOSH]
