A Filter‐Matrix Lattice‐Boltzmann Methodology for Convective Melting and Solidification

International Journal for Numerical Methods in Fluids, EarlyView.
We propose a new methodology for simulating melting and solidification that can be used in lattice‐Boltzmann schemes that are based on filter‐matrix collision operators. The methodology includes an iteration‐free source‐based enthalpy method for phase‐change and an immersed boundary technique.

Second‐Law Analysis of Mini/Micro Counterflow Parallel‐Plate Heat Exchangers: Optimizing Effectiveness by Minimizing Wall Entropy Production

Heat Transfer, EarlyView.
ABSTRACT We present an analytical and numerical study of the entropy production rate in laminar counterflow parallel‐plate heat exchangers, aiming to investigate the interplay between multidimensional wall conduction, entropy production, and the optimum wall conductivity that leads to maximum effectiveness.

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

Irrigation 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 ...

PolSpec: Polarisation‐Based Detection for Versatile, Cost‐Effective Rapid Hyperspectral Imaging

Journal of Biophotonics, EarlyView.
“PolSpec” is a fast, flexible, data efficient and cost‐effective technique for hyperspectral imaging utilising polarisation‐based spectral modulation. Using data‐efficient representation of spectral information on vector plots, it facilitates rapid visualisation and segmentation of spectral contrast to classify sample features. As a proof of concept, a
