Effect of real-world perturbations on wave breaking due to a sharp-crested superharmonic instability

The mechanism for the emergence of breaking water waves in deep water, based on the superharmonic instability of periodic Stokes waves, is tested for the effect of real-world perturbations (dissipation, approximation error, changes in depth, nonzero…

Application of Zonal Reduced-Order-Modelling to tire rolling simulation

Physic-based simulation remains a key enabler for real-world ever-growing complex industrial systems especially when crucial decisions are needed. While classical approaches have proven their accuracy and robustness over the years and come with a…

A purely analytic derivation of Bonnet surfaces

Bonnet has characterized his surfaces by a geometric condition. What is done here is a characterization of the same surfaces by two analytic conditions: (i) the mean curvature H of a surface in R^3 should admit a reduction to an ordinary…

The N-link model for slender rods in a viscous fluid: well-posedness and convergence to classical elastohydrodynamics equations

Flexible fibers at the microscopic scale, such as flagella and cilia, play essential roles in biological and synthetic systems. The dynamics of these slender filaments in viscous flows involve intricate interactions between their mechanical…

L1-Norm Redundant Delaunay Phase Unwrapping and Gradient Correction

This article deals with arrays of real numbers which have been reduced modulo 2h into theinterval [−h, h] where h > 0 is a positive real number. Such an array is said to be wrappedmodulo 2h. Often, the elements of these arrays correspond to…

Ultrasound-induced dense granular flows: a two-time scale modeling

Understanding the mechanisms behind the remote triggering of landslides by seismic waves at micro-strain amplitude is essential for quantifying seismic hazards. Granular materials provide a relevant model system to investigate landslides within the…

An Experimental Study Of The Vortical Structures In Supersonic Steam Jet Impinged On To The Wall

This study presents an experimental investigation into the impingement of a supersonic steam jet onto a wall. Steam was injected through a supersonic nozzle at a varying total pressure of 1.5-3.0 bars, producing a supersonic steam jet at a pressure…
