Lubrication Science, EarlyView.ABSTRACT Porous gas bearings (PGBs) enable high‐speed, oil‐free operation in modern rotating machinery. This study develops a coupled thermo‐hydrodynamic (THD) model for a cylindrical porous gas bearing lubricated with four working fluids—air, R‐134a, helium and hydrogen.

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.

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,

Numerical simulation of turbulence interaction noise applied to a serrated airfoil
Turbulent wakes generated by turbofan blades and interacting with the outlet guide vanes are known to bemainly contributing to broadband noise emission of aero-engines at approach conditions. Analytical approaches,such as the well-known Amiet's model can

DynaTOF: Time‐Resolved Noncontrast Cerebral MR Angiography Using Spatially Modulated RF Saturation
Magnetic Resonance in Medicine, EarlyView.ABSTRACT Purpose To develop a time‐resolved extension of three‐dimensional time‐of‐flight MR angiography, termed Dynamic TOF (DynaTOF), that exploits intrinsic RF saturation behavior to enable noncontrast visualization of cerebrovascular hemodynamics.

Dynamics of laminar pressure-driven channel flows laden with neutrally buoyant finite-size particles. [PDF]
, 2013 Since the pioneering work of Reynolds (1883), much effort has been allocated on the topic of laminar-turbulent transition regime in a single-phase flow, with special focusing on the unstable and intermittent natures of this regime (Mullin, 2011).

Interaction Between Vortex‐Induced Vibrations and Base Vibrations in Piezoelectric Harvesters
International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT In the present era, powering sensors using green energy is a significant challenge. One promising solution for the power supply of small sensors relies on piezoelectric energy harvesters excited by vortex‐induced vibrations (VIVs) generated by wind.
