Abstract Solid particles may experience different kinds of cohesive forces, which cause them to form agglomerates and affect their flow in multiphase systems. When such systems are simulated through computational fluid dynamics (CFD) programs, appropriate modelling tools must be included reproduce this feature. In review, these strategies addressed for various scales. After an introduction the forces (van der Waals, electrostatic, liquid bridge etc.), approaches categorized under three methodologies. For diluted slurries very fine particles, many researchers succeeded with pseudo‐single phase approaches, employing a model non‐Newtonian rheology. This was especially popular sludges anaerobic digestions or certain types soils. other cases, continuum‐based seem more adequate, including cohesiveness kinetic theory granular flows restitution coefficient. Geldart‐A experiencing van Waals primary focus studies. Finally, when each particle is modelled as discrete element, force can directly specified; widespread wet fluidization case. general overview main strategies, achievements, limits provided.

Enhancing soil fertility and maize productivity is crucial for sustainable agriculture. This study aimed to evaluate the effects of tillage practices, nitrogen management strategies, acidified hydrochar on productivity. The experiment used a randomized complete block design with split-split plot arrangement four replications. Main plots received shallow deep tillage. Subplots were treated (120 kg ha−1) from farmyard manure (FYM) urea, including control, 33% FYM + 67% urea (MU), 80% 20% (MF). Acidified treatments H0 (no hydrochar) H1 (with hydrochar, 2 t applied sub-sub plots. Deep significantly increased plant height, biological yield, grain ear length, grains ear−1, thousand-grain weight, content compared MU MF improved growth parameters yield over control. Hydrochar varied; enhanced components properties such as organic matter availability H0. Canonical discriminant analysis linked MU/MF characteristics. In conclusion, combined integrated enhances properties. These findings highlight importance selecting appropriate strategies production along addition. insights guide policymakers, agronomists, agricultural extension services in adopting evidence-based agriculture, enhancing food production, mitigating environmental impacts. implication this suggests undertake long-term application further clarification validation.

This study explores the potential of hydrochar derived from potato peels as a cost-effective option for efficient adsorption. Potato peel (PPH) was produced via hydrothermal carbonization (HTC) with KOH activation at 200 °C 2 h. The resulting then divided into three portions, two which underwent mixing urea followed by pyrolysis under N2 gas 600 and 3 h, respectively, in formation N-doped pyrochars (N-PPH.2 hrs N-PPH.3 hrs). Characterization using Brunauer-Emmett-Teller (BET), Scanning Electron Microscope (SEM), Energy-Dispersive X-ray Spectroscopy (EDS), Diffraction (XRD), Fourier Transform Infrared (FTIR) revealed distinctive properties. results showed that nitrogen atoms were effectively incorporated pyrochar, increasing significantly 3.7 to 8.3% 45.6% new compounds. modification impacted acidity basicity chemical surfaces pyrochar. particle sizve compounds 296.11 nm, demonstrated most adsorption Congo red (CR). efficiency achieved through various mechanisms, including pore filling, Lewis acid-base interaction, hydrogen bonding, π–π interaction. presence highly available functional groups, primarily pyridinic-N, pyrrolic-N, graphitic-N, further enhanced capacity. highest capacities observed 310 mg g−1 N-PPH-2Hr 400 N-PPH-3Hr, respectively. Increased temperature CR concentration correlated positively adsorption, following Freundlich isotherm pseudo second-order kinetics. Further, indicate prepared chars is endothermic, increases disorder, spontaneous process. highlights cost-effectiveness agro-industrial waste-derived removal, highlighting economic environmental benefits.
