Abstract:

The effect of greenhouse gas emissions contributing to the global warming is today becoming an increasingly important problem worldwide and has led to increased efforts being made on improving tribological performance of interacting surfaces in mechanical systems. Due to increasingly stringent CO2regulations, a reduced fuel consumption has become a key area of interest for the automotive industry where low cost, low emission solutions are continuously developed and where low friction alternatives to machine elements currently in use are evaluated. Crankshaft roller bearings have been shown to

Abstract:

The present work made use of existing thermal stress (fast moving distributed Hertzian heat source) solutions available to extend the isothermal stress solution to take into account effects of the flash temperature rise and the corresponding thermo-elastic stress components. The highlight of this new analytical model was the development of a thermo-mechanical yield factor, γ-factor, whereby critical conditions for which inelastic behaviour occurs can be predicted and the likelihood of failure estimated. The results of this work showed that failure by formation of welds can occur. This presumes

Abstract:

The thesis is concerned with the contact mechanics behaviour of non-conforming solids.

The radii of curvature of mating bodies in contact or impact give rise to these various nonconforming contact configurations and affect their contact characteristics, from those considered as semi-infinite solids in accord with the classical Hertzian th

Ultra-thin CIGS solar cells has shown a decrease in interface recombination and improved optical properties when adding a rear contact passivation layer of aluminium oxide.

Wetting, which addresses either spontaneous or forced spreading of liquids on a solid surface, is a ubiquitous phenomenon in nature and can be observed by us on a daily basis, e.g., rain drops falling on a windshield and lubricants protecting our corneas. The study of wetting phenomena can be traced back to the observation of water rising in a capillary tube by Hauksbee in 1706 and still remains as a hot topic, since it lays the foundation for a wide spectrum of applications, such as fluid mechanics, surface chemistry, micro/nanofluidic devices, and phase change heat transfer enhancement.

We study the evolution of a thin, axisymmetric, partially wetting drop as it evaporates. The effects of viscous dissipation, capillarity, slip, gravity, surface-tension gradients, and contact-angle hysteresis are taken into account in the regime in which the transport of vapour is dominated by diffusion. We find a criterion for when the contact-set radius close to extinction evolves as the square-root of the time remaining until extinction - the famous d<sup>2</sup>-law. However, for a sufficiently large rate of evaporation, our analysis predicts that a 'd<sup>13/7</sup>-law' is more appropria

Abstract:

A moving contact line is the idealized line of intersection between two immiscible fluids as one displaces the other along a solid boundary. The displacement process has been the subject of a large amount of theoretical and experimental research; however, the fundamental processes that govern contact line motion are still unknown. The challenge from an experimental perspective is to make measurements with high enough resolution to validate competing theories. An experimental method has been developed to simultaneously measure interface motion, dynamic contact angles, and local fluid velocity f

The present thesis treats the numerical simulation of immiscible incompressible two-phase flows with moving contact lines. The conventional Navier–Stokes equations combined with a no-slip boundary condition leads to a non-integrable stress singularity at the contact line.

Implementing slip conditions in an accurate way is not straight-forward and different regularization techniques exist where ad-hoc procedures are common.

Abstract:

The study of elastohydrodynamic lubrication (EHL) with rough surfaces results in a transient problem due to time varying geometry. In conditions where the A ratio (the ratio of smooth surface film thickness to composite roughness) is low, significant pressure deviations from the corresponding smooth surface results occur. The relative motion of asperity features on the two surfaces leads to cycling of these pressure deviations as surface features move through the nominal contact area. Micropitting, which is a form of surface distress seen in gears, may well be viewed as rolling contact fatigue

The exact mechanism with which a fluid interface interacts dynamically with a solid surface during wetting is still open to research. Among the many subjects addressed in this field in the literature, the "moving contact line problem" is one that has been ubiquitous since at least the 1970s, where a paradox in the description of the contact line was found to exist. The paradox in a few words is the next: macroscopic hydrodynamic models using the no-slip boundary condition will predict infinite shear stress close to the contact line.

Abstract:

This research investigates the effect of surface roughness on Thermo- Elastohydrodynamic Lubrication (TEHL) by Computational Fluid Dynamics (CFD). Traditionally, the Reynolds equation has been used to describe the flow of a lubricant for the TEHL problem, but this approach has some limitations. To overcome these, CFD is used in this research, as an alternative to solving the Reynolds equation. The commercial software packages ANSYS ICEM CFD 13.0 and ANSYS FLUENT 13.0 are employed to solve the Navier-Stokes equations. User-defined functions (UDFs) for the heat generated in the lubricant film, t
