Combining machine learning (ML) with computational fluid dynamics (CFD) opens many possibilities for improving simulations of technical and natural systems. However, CFD+ML algorithms require exchange of data, synchronization, and calculation on …

The present study investigates thermal sensitivity of a horizontal nanofluid layer which is subjected to conductivity and viscosity variations as linear functions of volume fraction of particles. A weak heterogeneous characteristic of the fluid is …

We analyze homothermal acceleration waves in complex materials (those with active microstructure) in the presence of internal constraints that link the temperature to a manifold-valued phase-field describing a generic material microstructure at a …

Twin-box decks are prone to vortex-induced vibration (VIV) at moderate wind speeds, and previous studies have shown a complex interplay between the flow and the two parallel box girders. OpenFOAM is used to model the aerodynamic and aeroelastic …

This study, framed within the context of the lower bound theorem of limit analysis, aims to assess the anti-funicular equilibrium of masonry arches and domes using a computational approach based on the constrained force density method. In contrast …

Recent investigations on active materials have introduced a new paradigm for soft robotics by showing that a complex response can be obtained from simple stimuli by harnessing dynamic instabilities. In particular, polyelectrolyte hydrogel …

In this paper, a nonlocal model for porous thermoelasticity is derived in the framework of the Mindlin’s strain gradient theory where the thermal behavior is based on the entropy balance postulated by Green–Naghdi models of type II or III. In this …

In this paper, we consider the linear theory for a model of a thermopiezoelectric nonsimple body as presented in Passarella and Tibullo (Entropy, https://doi.org/10.3390/e24091229 . 2022) in which the second displacement gradient and the second …

We demonstrate that the internal forces and moments in a shell structure can be described by 4 vectors in 3 dimensional space which could be used to express the equilibrium of a shell graphically. The internal forces and moments described by 2 of …

Fixed bed reactor simulations are often based on a porous media model with a single energy equation for the combined fluid and solid phases. In this energy equation, an effective thermal conductivity (which takes into account both the fluid and …

Friction is an ever-present force in our lives, affecting the interaction between objects in numerous ways. The common hypothesis of frictionless contact between a foreign rigid object (needle) and a target material during puncturing leads to a …

This study proposes a novel approach to accelerate computational fluid dynamics (CFD) simulations by employing simultaneous recurrence analysis. The methodology involves creating recurrent trajectories by recording the average values of samples …

This article was published with an erroneous version of Eq. 6 and therefore has been corrected.

Two-side accurate analytical estimates of the pull-in parameters of a carbon nanotube switch clamped at one end under electrostatic actuation are provided by considering the proper expressions of the electrostatic force and van der Waals …

Due to an unfortunate turn of events, Eqs. 52, 155, 156 and 157 contain errors. Please find below the correct version of the equations mentioned that should be regarded as the final version by the reader.

Time-varying mesh stiffness (TVMS) is an important excitation source of a planetary gear set. Sliding friction and spalling defects have significant effect on the TVMS. Accurate evaluation of the TVMS can help obtain the vibration characteristics …

The linear stability of a heat-exchanger tube modeled as a single-span cantilever beam subjected to cross-flow has been studied with two parameters: (1) varying stiffness of the baffle-cladding at the free end and (2) varying flow velocity. A …

Due to an unfortunate turn of events, this article was published without mention of the first author. Please find on this page all authors listed in the correct order that should be regarded as the final version by the reader.

To maintain the level of development renewable energy sources must step-in. One alternative is wind energy, it is a clean, stable and consolidated technology driven by the movement of air masses in the planetary boundary layer. This paper aims to …

Composite materials have been widely used in engineering applications due to their many advantages over conventional materials. Following this trend, researchers on rotordynamics have shown interest in the replacement of metallic by composite …
