Abstract

The effects of baffie design and number on longitudinal liquid movement in road tankers has been studied experimentally using a one-sixth scale model of a cryogenic road tanker. A number of baffie types have been investigated, including solid dished, oblique, spiral, round, and perforated designs. Time-series analysis of the forces on the tank and the pressures inside it during a typical stop showed a decreasing benefit with more than three baffies. The perforated baffies reduce liquid surging most effectively compared with all other types of baffie tested here. This perforated arrangement has the added advantage of being lightweight, enabling the tanker payload to be increased without compromising safety.
