Abstract:A new type of dilution water adding device was designed for the situation that the slurry and the dilution water could not be uniformly mixed in dilution water adding device used in engineering dilution water headbox, the mixed flow state of stock and dilution water was numerically simulated by computational fluid dynamics. The results indicated that compared with circular tubedilution water adding device, the dilution water addition of new type device was more uniform than that of circular tube dilution water addition device and the new type device had better dilution adjustment effect.
