Element 26 in our International Year of the Periodic Table series is iron – found in our blood, on the Red Planet, and also responsible for our own planet’s magnetic field. Blood’s red colour comes from the iron-containing haemoglobin. It’s not just the colour of blood that haemoglobin contributes; it’s also responsible for ferrying oxygen …

Part II presents a novel approach for predicting dynamic coefficients for a tilting pad journal bearing (TPJB) using computational fluid dynamics (CFD) and finite element method (FEM), including fully coupled elastic deflection, heat transfer, and fluid dynamics. Part I presented a similarly novel, high fidelity approach for TPJB static response prediction which is a prerequisite …
This paper presents the first simulation model of a tilting pad journal bearing (TPJB) using three-dimensional (3D) computational fluid dynamics (CFD), including multiphase flow, thermal-fluid, transitional turbulence, and thermal deformation of the shaft and pads employing two-way fluid–structure interaction (FSI). Part I presents a modeling method for the static performance. The model includes flow between …
