Flow Characteristic of Hydraulic Headbox Based on Complementary Pulp Distribution
In order to study effect of complementary pulp distribution, computational fluid dynamic (CFD) was used to research flow characteristic of hydraulic headbox based on complementary pulp distribution. Mass flow rate out of mixing chamber and velocity distribution at slice of headbox were experimented. The results showed that because of simplified design, there were a little gradient of velocity a...
متن کاملStudy on the NN Decoupling Control System of Air-cushioned Headbox
The headbox is the key hinge to link the pulp supply system with the sheet forming in the papermaking process. The primary parameters include the total pressure and the stock level which couple each other in the box, and they decide the distribution of the web cross-directional basis weight and influence the paper forming quality. Here taking widely used air-cushion type headbox as the plant, a...
متن کاملSynthesis and characterization of magnetic γ- Fe2O3 nanoparticles: Thermal cooling enhancement in a sinusoidal headbox
Nano-size maghemite (γ-Fe2O3) particles were prepared in one step using ultrasound radiation. The obtained nanoparticles were characterized by SEM, TEM , XRD, FTIR, and VSM. The results revealed that the synthesized nanoparticles were spherical, mono-dispersed and uniform. Furthermore, the crystalline structure of nanoparticles endorsed by X-ray diffraction study. The FTIR spectra have provided...
