Travelling-wave similarity solutions for an unsteady shear-stress-driven dry patch in a flowing film [PDF]
, 2013 We investigate unsteady flow of a thin film of Newtonian fluid around a symmetric slender dry patch moving with constant velocity on an inclined planar substrate, the flow being driven by a prescribed constant shear stress at the free surface of the film

Comparison of modelling approaches for liquid fluidized beds
The Canadian Journal of Chemical Engineering, EarlyView.Abstract This study presents a comparison of three promising numerical models for the detailed simulation of liquid–solid fluidized bed. These models differ in their treatment of the solid phase, ranging from treating each particle individually to treating the collection of particles as a continuum.

Analysis of Flutter Characteristics for Composite Laminates in Hypersonic Yawed Flow
AerospaceThis paper investigates the flutter characteristics of composite laminates in hypersonic yawed flow using numerical simulations. The governing equations are derived based on Hamilton’s principle and were discretized using the assumed mode method.

Separated flow over bodies of revolution using an unsteady discrete-vorticity cross wake. Part 2: Computer program description [PDF]
A method is developed to determine the flow field of a body of revolution in separated flow. The computer was used to integrate various solutions and solution properties of the sub-flow fields which made up the entire flow field without resorting to a ...

On Unsteady Flow of a Dissociating Gas
Defence Science Journal, 1981 Lighthill's model of an ideal dissociating gas has been exploited to study three dimensional unsteady flows in the absence of dissipative mechanisms. Expressions for the tangent, principal normal and binormal vectors, curvature and torsion of streamlines, variations of pressure along streamlines and their principal normal and binormal have been ...

Acoustic‐driven surface cleaning with millimeter‐sized bubbles at translational resonance
Droplet, EarlyView.Time‐lapse visualization comparing bubble trajectories. The top panel (0 Hz) shows a bubble's linear path under no acoustic forcing, while the bottom panel (50 Hz) demonstrates the oscillatory motion induced by acoustic waves at a resonance mode. This mechanism holds promising potential for applications such as surface cleaning.

Numerical simulation of steady and unsteady asymmetric vortical flow [PDF]
The unsteady, compressible, thin-layer, Navier-Stokes (NS) equations are solved to simulate steady and unsteady, asymmetric, vortical laminar flow around cones at high incidences and supersonic Mach numbers. The equations are solved by using an implicit,
