An Experimental Investigation on the Impact of Burner Height and Location on the Characteristics of Externally Venting Flames

open access: yesFire and Materials, EarlyView.
ABSTRACT Fire sources in actual compartment fires exhibit a predominantly uneven spatial distribution. In this context, the impact of the height and location of the fire source, as well as the heat release rate (HRR) of the fire, on the thermal characteristics of Externally Venting Flames (EVF) is experimentally investigated.

Effect of Microchannel Geometry on Nanoparticle Deposition in Nanofluid Flow

open access: yesInternational Journal for Numerical Methods in Fluids, EarlyView.
This study numerically analyzed nanoparticle deposition in microchannels with varying geometries. Deposition per unit area decreases significantly with increasing bend angle (28.612 to 8.941 between 30° and 120°) and bend radius (11.922 to 4.769 between 0.2 and 0.4 mm). Acute bends and small radii enhance centrifugal forces and flow separation, leading

On the Variability of Results for Cylinder Flow: A Systematic Analysis of Parameter Sensitivity Within the Lattice Boltzmann Method

open access: yesInternational Journal for Numerical Methods in Fluids, EarlyView.
This study systematically investigates the variability of cylinder flow results. We provide a comprehensive overview of literature values and, using the lattice Boltzmann method (LBM), show that insufficient convergence studies and variations in simulation parameters are a plausible cause for the significant spread in data.

New Thermal Lattice Boltzmann Method for Modeling Heat Transfer Problems Considering Temperature‐Dependent Properties

open access: yesHeat Transfer, EarlyView.
ABSTRACT Several engineering problems involve the need to model conjugate heat transfer processes considering the temperature‐dependence of the material properties. Consequently, a simulation tool capable of modeling this process is of great interest. In this context, the present work proposes a thermal lattice Boltzmann method (TLBM) for modeling the ...

From Physiology to Bioheat Simulation: A Data‐Driven Framework for Core Temperature Initialization

open access: yesHeat Transfer, EarlyView.
ABSTRACT Accurate initialization of core body temperature is a critical yet often overlooked component of bioheat transfer models, particularly when such models are applied to heterogeneous populations and real‐world environmental conditions. Conventional bioheat simulations typically rely on fixed or idealized core body temperature values derived from

Influence of Drain and Operational Parameters on Backwash Cleaning Efficiency in a Commercial Sand Filter Model

open access: yesIrrigation and Drainage, EarlyView.
ABSTRACT Some studies have demonstrated the influence of the drainage system design on the hydraulic behaviour and on the expansion of the filter bed during the backwashing process, with a presumed effect on removal efficiency. The objective was to evaluate the influence of the drainage system design of a commercial sand filter model, the operating ...

From Empire to Aid: Analysing Persistence of Colonial Legacies in Foreign Aid to Africa

open access: yesJournal of International Development, EarlyView.
ABSTRACT For decades now, Western development agencies and donors have been castigated for their colonial biases in providing aid to Africa. It is well established that donors provide considerably more foreign aid to their former colonies relative to other countries.

Experimental Study on Polymer–Polymer Interfacial Thermal Resistance

open access: yesMacromolecular Theory and Simulations, Volume 34, Issue 2, March 2025.
Interfacial thermal resistance (ITR) in polymer–polymer interfaces is experimentally measured in this paper by the multi‐layered bulk sample approach. Based on numerical simulation and experimental verification, new techniques of layer‐overlapping samples are developed.
