Abstract
This report presents the results of a study on center push-pull ventilation for open surface tanks. The study was performed on a full-scale mock tank which had fixed dimensions. The objectives of the study were as follows: 1) to develop a curve for the minimum pull flow for a given push flow (called a match point curve); 2) to develop velocity profiles for one match point; and 3) to characterize the general airflow patterns for the system. The respective methods used for the objectives of the study were as follows: smoke, put into the push blower inlet, with visual observation; smoke tube traces and velocity measurements with a hot wire anemometer; and smoke tube traces. All three objectives of the study were accomplished and are presented in the report along with a discussion of the results. Some recommendations are also made for future research.
