Eulerian-Eulerian models incorporated with the kinetic theory of granular flow were widely used in the simulation of gas-solid two-phase flow, while the effects of mesoscale structures such as particle clusters and gas bubbles could not be considered adequately if traditional homogeneous drag models were adopted in the coarse grid simulations. The ...

Clarification operations are vital to extract high-quality products from cane molasses. Ultrafiltration (UF) is very efficient for this purpose, although membrane fouling limits its large-scale application. In this work, five commercially available polyethersulfone UF membranes were evaluated for the clarification of molasses, whereby 30-100 kDa me...

The hydrodynamic characteristics of tapered bubbling/turbulent fluidized beds with/without gas distributor are simulated based on the structure-based drag model. Besides the only parameter of gas voidage (epsilon(g)) contained in the original drag model, the heterogeneous drag index (H-d) for the tapered fluidized bed (TFB) also includes the parame...

The product distribution and reaction mechanism of steam pyrolysis of Longkou oil shale kerogen was researched by molecular dynamics simulation. Molecule structural model used in the simulation was constructed according to the analysis results of a series of detection about kerogen extracted from Longkou oil shale. Reactive force field molecular dy...

The thermal behavior of the hydrochars from co-hydrothermal carbonization (co-HTC) of sawdust (SD) and sewage sludge (SS) was investigated using thermogravimetric analysis. The comprehensive devolatilization index indicated that the devolatilization performance of SS was decreased by HTC, while it was significantly improved 7.38-23.69 times by co-H...
