Abstract

To reduce backmixing in the flow-type horizontal stirred vessel, a perforated partition plate was attached and the effects of shape of plate on the mixing characteristics were studied under various operating conditions. Results were analyzed in terms of mixing models to evaluate the extent of preventing backmixing. It enabled us to estimate the extent of back flow at the perforated partition plate from power consumption.
