The Subject

Courses in mechanical engineering usually introduce the theory of axial-flow turbo-machines in terms of simple velocity triangles representing the bulk flow of ideal compressible fluid through the blade passages. A distinctive practical difference, peculiar to steam turbines (ST), is the presence of liquid-water in the flow field. The steam wetness in such turbines is widely known to be doubly-damaging, leading to both loss of efficiency and to mechanical damage (erosion, etc.) of the machine components. Over recent decades, a whole new field of mechanical engineering science has evolved on the subject of wetness in steam turbines, and general practices have been established within the industry. This article reviews the general effects that are of major importance to the turbine designer/engineer, power plant operator, and especially to researchers in this field.

Discussion of Hwang and Chen's constraint equations to eliminate order, circuit and branch defects for the paper: Defect-free synthesis of Stephenson-III motion generators, published in Journal of Mechanical Engineering Science, 2008; 222: 2485–2494

Optimum Synthesis

Many studies to find solutions for the optimum synthesis problems of linkage mechanisms for path, motion or function generation have appeared in the literature. However, their main focus has been on the development of optimization algorithms or synthesis methods without the handling of the defect problems or only with consideration of the same assembly mode. Hwang and Chen's pioneering work proposed a defect-free optimum synthesis method with constraint equations to eliminate order, circuit and branch defects for Stephenson III six-bar motion generators. However, their proposed constraint equations for the three types of defects are incomplete or not clear enough. In this discussion, we not only examine these faults but also offer the correct and complete constraints to eliminate the three types of defects.

The Impact

Three publications from Part C which strongly influenced the development of the field of lubrication in human joints are revisited and their impact on the field is outlined. Furthermore, the impact of the Journal of Mechanical Engineering Science on the field of lubrication and wear in living and artificial human joints is analysed. ‘Analysis of “boosted lubrication” in human joints’ by Duncan Dowson, Anthony Unsworth, and Verna Wright appeared in 1970, ‘The lubrication of porous elastic solids with reference to the functioning of human joints’ by Gordon R. Higginson and Roger Norman was published in 1974, and ‘Engineering at the interface’ by Duncan Dowson addressed the audience in 1992.

AbstractBertolt Brecht once closed a text with the words “We are disappointed to see the curtain close and all questions are left unanswered” [1]. In this book, it has become clear that uncertainty is immanent in the product life cycle of technical systems in mechanical engineering from (B) production, (C) usage, (D) reuse to (E) sourcing. The latter is the starting phase of the following sequence B, C, D, E. Uncertainty has been relevant since the beginning of the industrialisation, cf. Theodor Fontane’s ballad ‘The Tay Bridge’ quoted in Chap. 10.1007/978-3-030-78354-9_1 and this will continue to be so. Hence, we will never see “the curtain close”, but a perpetual contribution of engineering science, applied mathematics, law and further branches of science to master uncertainty in mechanical engineering.
