Clogging Analysis in Drip Irrigation Systems: CFD and DEM Approaches

Irrigation 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 ...

New Calculations of the Turbulence-Turbulence Contribution to the Wind Noise Pressure Spectra within Homogeneous Anisotropic Turbulence [PDF]

arXiv
The turbulence-turbulence interaction and the turbulence-shear interaction are the sources of intrinsic pressure fluctuation for wind noise generated by atmospheric turbulence. In previous research [Yu et al., J. Acoust. Soc. Am. 129(2), 622-632 (2011)], it was shown that the measured turbulent fields outdoors can be realistically modeled with ...

Anisotropy and asymmetry in fully developed turbulence [PDF]

arXiv, 2007
Using experimental longitudinal and transverse velocities data for very high Reynolds number turbulence, we study both anisotropy and asymmetry of turbulence. These both seem to be related to small scale turbulent structures, and to intermittency.

Numerical Simulation of Atmospheric Turbulence for Assessment of Wind Turbine

Journal of Fluid Science and Technology, 2011
To obtain basic understanding for the development of atmospheric turbulence assessment technique for wind-energy application, we examine the performance of turbulence simulation using the large-eddy simulation technique, focusing on grid dependency of ...

Production of hydroxyectoine from biogas by an engineered strain of Methylomicrobium alcaliphilum using a novel Taylor‐flow bioreactor

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND The production of compatible solutes, such as ectoine and hydroxyectoine, is of great interest due to their industrial and biotechnological applications. Methylomicrobium alcaliphilum was genetically engineered to replace a native gene with a heterologous one, aiming to enhance ectoine production.

Exploring Time‐Domain Femtosecond Rotational Coherent Raman Scattering for Diagnostics

Journal of Raman Spectroscopy, EarlyView.
The diagnostic potential of femtosecond (fs) rotational coherent Raman scattering (RCRS) in the time domain is initially investigated. Experiments in air and pure nitrogen are reported, revealing the temperature sensitivity in the recorded fs‐RCRS temporal scans.

How to Augment for Atmospheric Turbulence Effects on Thermal Adapted Object Detection Models? [PDF]

arXiv
Atmospheric turbulence poses a significant challenge to the performance of object detection models. Turbulence causes distortions, blurring, and noise in images by bending and scattering light rays due to variations in the refractive index of air. This results in non-rigid geometric distortions and temporal fluctuations in the electromagnetic radiation
