Mass Exchange Flow Process in Side Channel Pumps: Effects of Different Geometrical Parameters

Energy Science &Engineering, EarlyView.
Figure 1 shows the Mass Flow Exchange (MFE) in the impeller at z = 7.5 × 10−3 m at 1.0 Q/QBEP, operating point for impeller scheme 1 (IMP 1), and impeller scheme 2 (IMP 2). The flow begins to exit the impeller at the outer radius and enters at the inner and central radii. IMP 1 exhibits more flow in and out compared to IMP 2. ABSTRACT The functionality

Coupled Fluid–Structure–Acoustic Analysis of Flow‐Induced Noise Control Using an Elastic Baffle in a Micro Channel

Energy Science &Engineering, EarlyView.
This research explores how fluid flow, structural movement, and sound interact in an elastic baffle system. Using a numerical approach based on the finite element method, the study analyzes how noise and vibrations change with different baffle configurations. The findings reveal that shortening the baffle by half reduces noise transmission by 9%, while

Local Polynomial Regression and Filtering for a Versatile Mesh‐Free PDE Solver

International Journal for Numerical Methods in Fluids, EarlyView.
A high‐order, mesh‐free finite difference method for solving differential equations is presented. Both derivative approximation and scheme stabilisation is carried out by parametric or non‐parametric local polynomial regression, making the resulting numerical method accurate, simple and versatile. Numerous numerical benchmark tests are investigated for

CFD Analysis of Dual‐Layer PCM Roofs for Thermal Mitigation in Residential Buildings

Heat Transfer, EarlyView.
ABSTRACT This study presents a computational fluid dynamics analysis of dual‐layer phase change material (PCM) roofs for passive cooling in residential buildings under the hot and humid climate of Bangladesh. A three‐dimensional transient model was developed in ANSYS Fluent using the enthalpy–porosity approach to simulate coupled heat conduction ...

Strain‐Induced Density Fluctuations in Glassy Polymers

Macromolecular Rapid Communications, EarlyView.
Strain deformation induces the density fluctuations in glassy polymers, resulting in shear‐thinning behavior. ABSTRACT Deformation of glassy polymers induces plastic flow as a result of mechanical instability, ultimately leading to cavitation and fracture of the liquid. Thus, understanding the origin of such mechanical instability is crucial.

Experimental Study on Polymer–Polymer Interfacial Thermal Resistance

Macromolecular 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.

Thermal Planar and Radial Free Jets for An Ostwald‐de Waele Fluid With Shear‐Rate Dependent Thermal Diffusivity

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT The planar and radial thermal free jets for forced convection of a non‐Newtonian power‐law fluid are investigated. The thermal diffusivity is dependent on the shear‐rate and is not a constant. The flow in planar and radial thermal free jets is governed by the momentum, continuity and energy balance equations. In the stream‐function formulation,

Kinetic Compensation of Barrel Launch Under High‐Speed Solid‐Phase Particulate Impacts

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT An accurate launch‐dynamics computational method is critical for barrel weapon service life assessment and multiphase physics field refinement. Given the lack of studies on the solid‐phase buildup behavior at the projectile base, this paper provides an improved method for calculating the launching dynamics under high pressure and high speed ...
