Numerical simulation of mould filling process for pressure plate and valve handle in LFC [PDF]

China Foundry, 2010
In lost foam casting (LFC), the distribution of polymer beads during the bead filling process is not uniform, and the collision between polymer beads determines the distribution of two-phase flow of gas and solid.

Computational fluid dynamics simulations of airflow through the nasal passages of rhinolophoid bats

The Anatomical Record, EarlyView.
Abstract The nasal passages of bats that emit their echolocation call through their nostrils have adapted for sound emission as well as standard respiratory and olfactory functions. Rhinolophids, hipposiderids and rhinonycterids all use a high duty cycle (HDC) echolocation strategy.

Engineering Biology Beyond Single Genes: Advances and Challenges in Multiplex Genome Editing

Animal Research and One Health, EarlyView.
Multiplex genome editing is transforming genome engineering from single‐gene perturbation to network‐level control, yet its broader application remains limited by challenges in gRNA array engineering, delivery technologies, and safety management. Emerging AI‐driven approaches are accelerating guide RNA design and CRISPR effector optimization for ...

Potential contribution of biomass gasification‐based technology in energy transition: a technical review coupled with bibliometric studies

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Biomass gasification technology has been extensively researched around the world; however, there is a need to evaluate the current research landscape and evolutionary direction of research in the broader context of energy transition. A systematic bibliometric analysis of the Web of Science database was performed for articles that fall within ...

A Coupled CFD-DEM Approach to Model Reactive Granular Beds

BHM Berg- und Hüttenmännische Monatshefte
AbstractPacked and moving bed reactors are widely used in process industry to process granular material. Shaft furnaces are one example of this. Due to their counterflow layout, a high thermal efficiency can be achieved. Shaft furnaces have a wide range of length and time scales that makes them challenging to model.

Coupled CFD-DEM simulation of separation process in combine harvester cleaning devices

, 2017
The present paper contributes to the application of the coupled CFD-DEM approach (CFD – Computational Fluid Dynamics; DEM – Discrete Element Method) for the simulation of the separation process of grain and material other than grain (MOG) in the cleaning device of a combine harvester.

A Method for Optical Quantification of Local Oxygen Limitations in Multiphase Bioreactors

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Spatial oxygen limitation is a major source of physiological stress and metabolic, scale‐dependent heterogeneity in aerobic bioprocesses. In gas‐liquid stirred tank reactors, oxygen availability is governed by hydrodynamics and mass transfer and is therefore inherently non‐uniform.

Coupled CFD-DEM simulation of fluids and bubbles in a stirring tank

AIP Advances
The multiphase flow within a stirring tank predominantly exhibits complex turbulent motion, characterized by nonlinear and intricate interactions among different fluids. By treating the gas–liquid two-phase flow as a “fluid particle” system, we conducted numerical simulations of this flow in a stirring tank using a coupled computational fluid dynamics ...

CFD-DEM simulation of slurry particle infiltration in granular soils [PDF]

Over recent decades, the slurry pressure balance (SPB) method has gained popularity due to its safety, efficiency, and environmental advantages, especially in undersea and river-crossing tunnels with high groundwater pressures. By employing a pressurised
