Einfluss der Partikelgröße auf den Durchgangswiderstand von partikulären Systemen Effects of Particle Size on the Volume Resistance of Particular Systems

open access: yesChemie Ingenieur Technik, EarlyView.
In einer konzentrischen Messzelle wurde die Abhängigkeit des Durchgangswiderstandes von Partikelschüttungen von den Produkteigenschaften Partikelgröße und Dispersität in Luft untersucht. Grundsätzlich ist festzustellen, dass mit steigender Partikelgröße der Durchgangswiderstand signifikant ansteigt.

Local Path Planning for Autonomous Vehicles Based on the Natural Behavior of the Biological Action-Perception Motion

open access: yesEnergies, 2022
Local path planning is a key task for the motion planners of autonomous vehicles since it commands the vehicle across its environment while avoiding any obstacles. To perform this task, the local path planner generates a trajectory and a velocity profile,

Advancing the concept of windows of opportunity to explore the dynamics of the sustainability transition: The development of the EV market in the UK

open access: yesEuropean Policy Analysis, EarlyView.
Abstract In this study, we seek to understand the interplay between industry and policy, to explain how and why the UK shifted from the promotion of low‐emission road transportation, to policy based on zero tailpipe‐emission electric vehicles (EVs), as part of its evolving net zero ambitions.

Transmission Water Losses at South African Irrigation Schemes: A Case Study of the Vaalharts Irrigation Scheme

open access: yesIrrigation and Drainage, EarlyView.
ABSTRACT Irrigation water supply is under scrutiny because of dwindling water resources. Most irrigation water in South Africa (SA) is transmitted by canals. Transmission water loss (TWL) accounts for 12% of the irrigation water losses in SA. Therefore, there is a need to investigate and understand the major parameters influencing TWL at Vaalharts ...

Clogging Analysis in Drip Irrigation Systems: CFD and DEM Approaches

open access: yesIrrigation and Drainage, EarlyView.
ABSTRACT Clogging represents a critical challenge that undermines the efficiency and sustainability of drip irrigation systems by inducing uneven water distribution and increasing maintenance requirements. In this study, the phenomenon of clogging in drip emitters was investigated via computational fluid dynamics (CFD) in conjunction with the discrete ...
