Statistical and Numerical Analysis of Conjugate Heat and Momentum Transfer in an Open Cavity With a Thick Wall Using Cu–Water Nanofluid

open access: yesEngineering Reports, Volume 8, Issue 3, March 2026.
Considered physical model and effect of Nuav(τ = 0.1) for Re and ϕ at τ = 0.1. ABSTRACT Although open cavity configurations are common in modern electronic and solar applications, limited attention has been given to thick‐walled hollow cavity designs, particularly in the context of comprehensive sensitivity analysis.

Finite Element Analysis and ANN Validation of Mixed Convection Nanofluid Flow in a Star‐Shaped Corrugated Cavity With Multiple Heated Baffles

open access: yesEngineering Reports, Volume 8, Issue 3, March 2026.
This study carefully examines the mixed convection heat transport properties of a water–Al2O3 nanofluid inside a corrugated chamber with heated baffles in the shape of a star. The effects of different Rayleigh numbers, nanoparticle volume fractions, and baffle placement are carefully evaluated, and the cavity is subjected to buoyancy forces. The finite

Comparison of Newton-Raphson Algorithm and Maxlik Function

open access: yesJournal of Advanced Engineering and Computation, 2018
Our main objective is in antagonizing the performance of two approaches: the Newton-Raphson (N-R) algorithm and maxLik function in the statistical software R to obtain optimization roots of estimating functions.

Coupled Water Flow and Solute Transport in Variably Saturated Agricultural Soils: A Python‐Based Numerical Simulation

open access: yesEngineering Reports, Volume 8, Issue 3, March 2026.
Agricultural intensification and the increasing use of fertilizers and irrigation have significantly improved crop productivity but have also led to growing concerns over groundwater contamination and inefficient water usage. When solutes like nitrates and pesticides seep past the root zone, they not only deplete soil fertility but also endanger the ...

A Multiphysics Finite‐Element Framework for Magnetically Tunable Electrochemical Hydrogen Sensors Based on Cs/GO/Fe3O4/PANi Hydrogels

open access: yesEngineering Reports, Volume 8, Issue 3, March 2026.
A multiphysics finite‐element model is developed to elucidate magnetically tunable electrochemical hydrogen sensing in a Cs/GO/Fe3O4/PANi hydrogel nanocomposite. The framework couples hydrogen diffusion, electrochemical kinetics, charge transport, and superparamagnetic Fe3O4 alignment to predict sensor performance.

A New Unit‐Lindley Mixed‐Effects Model With an Application to Electricity Access Data

open access: yesEnvironmetrics, Volume 37, Issue 2, March 2026.
ABSTRACT This paper introduces a novel unit‐Lindley mixed‐effects model (NULMM) within the generalized linear mixed model (GLMM) framework, designed for analyzing correlated response variables bounded within the unit interval. Parameter estimation was conducted via maximum likelihood, using Laplace approximation and adaptive Gaussian‐ Hermite ...
