Simulation studies of stick and slip at the solid-liquid boundary. Successful practical application of computational rheology to polymer processing, to adhesion and to the understanding of lubrication at very high shear rates, among other problems, needs both an adequate description of the fluid - a constitutive equation - and the prescription of proper boundary conditions.The constitutive model problem has been extensively studied, and this proposal seeks to address the question of proper bound ....Simulation studies of stick and slip at the solid-liquid boundary. Successful practical application of computational rheology to polymer processing, to adhesion and to the understanding of lubrication at very high shear rates, among other problems, needs both an adequate description of the fluid - a constitutive equation - and the prescription of proper boundary conditions.The constitutive model problem has been extensively studied, and this proposal seeks to address the question of proper boundary conditions for viscoelastic flow at interfaces between a flowing fluid and a solid surface. This vital area has not been thoroughly studied theoretically and computationally, and we seek to clarify the mechanisms by using molecular dynamics.Read moreRead less

Understanding the role of nanoparticles in water based lubrication. This project seeks to understand the role of nanoparticles in the lubrication of hot strip rolling and then to develop novel nano-additive water-based lubricants to solve a long-standing issue for the steel-making industry. Lubrication significantly affects the surface quality of hot-rolled strips, roll wear and energy consumption in the steel-making industry. Currently, oil-based lubricants are used. However, their lubricant ef ....Understanding the role of nanoparticles in water based lubrication. This project seeks to understand the role of nanoparticles in the lubrication of hot strip rolling and then to develop novel nano-additive water-based lubricants to solve a long-standing issue for the steel-making industry. Lubrication significantly affects the surface quality of hot-rolled strips, roll wear and energy consumption in the steel-making industry. Currently, oil-based lubricants are used. However, their lubricant effect is considerably reduced by the use of high pressure cooling water, and the waste discharge is of environmental concern. Successful outcomes for the project are expected to improve product quality and reduce resource use.Read moreRead less
Nanostructured Ionic-Molecular Hybrid Liquids. This project aims to produce a new class of green, economical, non-toxic, low volatility, designer solvents from mixtures of one or more molecular components, and ionic liquid-inspired salts. By manipulating the intermolecular forces between components of these nanostructured ionic molecular "hybrid liquids" (HLs), we will develop new understanding of how liquid structure arises from the nano- to the colloidal and even micro-scale.

By manipulating the intermolecular forces between components of these nanostructured ionic molecular "hybrid liquids" (HLs), we will develop new understanding of how liquid structure arises from the nano- to the colloidal and even micro-scale. HLs will enable the development novel complex fluids, which are liquids containing interacting particles, polymers, and/or surfactants. Lubricants developed from HL based complex fluids will act as a “test-bed” application for the new understanding this project will engender, towards use of HLs in diverse areas.Read moreRead less
Environmentally friendly lubricants for higher productivity in cold rolling. This project aims to develop an oil free aqueous lubricant for cold rolling to replace the existing oil-in-water emulsion.

This project aims to develop an oil free aqueous lubricant for cold rolling to replace the existing oil-in-water emulsion. The lubricant will be molecularly engineered to combine synergy between nanomechanics and tribochemistry of boundary additives to deliver integrated functionalities in the strip rolling. During cold rolling , lubricant starvation often occurs at high speed and it has restricted the productivity of the rolling mill and affected the strip gauge and surface quality. Expected outcomes of this project include an innovative oil free lubricant with significant environmental benefits and an ability for manufacturers to improve productivity by operating at higher speeds, lower costs, and achieve superior strip surface quality.Read moreRead less

Tribological contact of work roll in hot rolling. Steel and aluminium manufacturers form their products by shaping a hot metal billet using, for example, presses and rollers which contact the rapidly cooling metal in the production line. The economic benefits of lubrication, reduced rolling force (up to 25%), reduced roll wear and extended roll life (up to 40%), reduced down time due to roll change, and better strip quality are very significant for these manufacturing processes.
