Numerical algorithms for EHL

Project description

Elastohydrodynamic lubrication (EHL) concerns the behaviour of a non-Newtonian lubricating fluid which acts to keep two elastically-deformable contacts apart by working against an applied load that is trying to force the contacting elements together. This scenario occurs in a wide variety of important engineering situations and so gaining a thorough understanding of EHL can lead to significant improvements in the efficiency of components such as those occuring in engines and other machinery. The importance of this is obvious in today's society where improved engine efficiency can lead to energy savings and has major positive environmental implications.

The aim of this project is to investigate the direct use of nonlinear solution strategies, such as Newton's method, for this problem. To achieve maximum efficiency preconditioned inner-iterations are required for each step of the nonlinear solver. These must also achieve an optimal efficiency if the overall algorithm is to be competitive with existing solution strategies.

This work builds on a long history of research in the group which has developed computational algorithms and tools that are used in industry as well as academia.
