Professor Duncan Dowson had close connections with industry throughout his academic career, and viewed industrial tribological challenges as problems to be solved and as a source of new ideas. Professor Dowson’s famous work on a numerical solution for the lubrication of an elastohydrodynamic line contact, with professor Higginson, was motivated by the need to better understand gear lubrication. These first calculations took 18 months to complete(!), and simpler correlation functions fitted to numerical simulations were developed to enable tribologists in academia and industry to apply elastohydrodynamic lubrication theory without the need for full scale models. Industrial partners such as Shell supplied high-pressure fluid properties required for the elastohydrodynamic calculations (such as the pressure coefficient of viscosity and the way in which lubricant density varies with pressure). Professor Dowson also famously served on the Jost Committee, which quantified, for the first time, the financial impact of tribology, and highlighted that investments in good tribological practices would pay for themselves many times over. It should be remembered that in setting up the Jost Committee, the UK Government specifically asked the committee ‘to investigate the state of lubrication education and research and to establish the requirements of industry in this regard’. Personal memories of the significant collaborations that I was involved with, as an industrial research scientist, with Leeds University from the mid-1990s to around 2013, which predominantly focused on piston ring tribology are also included as is a brief discussion of the Leeds-Lyon Symposia on Tribology.

Duncan Dowson 教授在整个学术生涯中与工业界有着密切的联系，并将工业摩擦学挑战视为需要解决的问题和新思想的来源。Dowson 教授与 Higginson 教授在弹性流体动力线接触润滑的数值解决方案方面的著名工作是出于更好地了解齿轮润滑的需要。这些最初的计算需要 18 个月才能完成（！），并且开发了适合数值模拟的更简单的相关函数，使学术界和工业界的摩擦学家能够应用弹性流体动力润滑理论，而无需全尺寸模型。壳牌等工业合作伙伴提供了弹性流体力学计算所需的高压流体特性（例如粘度的压力系数和润滑剂密度随压力变化的方式）。Dowson 教授还曾在 Jost 委员会任职，该委员会首次对摩擦学的财务影响进行了量化，并强调对良好摩擦学实践的投资将多次获得回报。值得一提的是，英国政府在设立约斯特委员会时，特别要求委员会“ 并强调对良好摩擦学实践的投资将获得数倍的回报。值得一提的是，英国政府在设立约斯特委员会时，特别要求委员会“ 并强调对良好摩擦学实践的投资将获得数倍的回报。值得一提的是，英国政府在设立约斯特委员会时，特别要求委员会“调查润滑教育和研究的状况，并确定工业在这方面的要求。从 1990 年代中期到 2013 年左右，我作为一名工业研究科学家参与了与利兹大学的重大合作的个人回忆，这些合作主要集中在活塞环摩擦学上，以及对利兹-里昂的简要讨论摩擦学研讨会。
