On the Behavior of Two C1 Finite Elements Versus Anisotropic Diffusion

open access: yesInternational Journal for Numerical Methods in Fluids, EarlyView.
Bi‐cubic Hemite‐Bézier and reduced cubic Hsieh‐Clough‐Tocher finite elements, of class C1, are compared for the solution of a highly anisotropic diffusion equation. They are tested numerically for various ratios of the diffusion coefficients on different meshes, even aligned with the anisotropy.

Incremental Model Order Reduction of Smoothed‐Particle Hydrodynamic Simulations

open access: yesInternational Journal for Numerical Methods in Fluids, EarlyView.
The paper presents the development of an incremental singular value decomposition strategy for compressing time‐dependent particle simulation results, addressing gaps in the data matrices caused by temporally inactive particles. The approach reduces memory requirements by about 90%, increases the computational effort by about 10%, and preserves the ...

Perspective Projection of an Ellipse and an Ellipsoid for Analytical View Factor Evaluation

open access: yesHeat Transfer, EarlyView.
ABSTRACT Radiative view factors are fundamental quantities for evaluating radiative heat transfer between different surfaces. While analytical expressions of view factors have been evaluated for various types of basic geometries, including circular disks and spheres, extending these solutions to more complex geometries, such as ellipses and ellipsoids ...

Entropy Generation Analysis due to Permeable Exponential Stretching in Boundary Layer Flows

open access: yesHeat Transfer, EarlyView.
ABSTRACT Entropy generation represents the irreversible loss of useful energy in thermal–fluid systems, directly reducing efficiency in applications, such as microelectronics cooling, nanofluid‐based heat exchangers, and polymer processing. This study investigates entropy generation in a two‐phase viscoelastic nanofluid flow over a permeable ...
