Abstract: In 1957, a research program was initiated for the study of radial lip seals. Results of this study indicated that there was a lack of seal technology concerning the seal lip characteristics ...

Abstract: This paper discusses research into the possibility of reducing gear tooth root stresses by adding internal stress relief features. For many years, gear designs have improved with the incremental ...

Abstract: The discrete-element model for flows over rough surfaces was recently modified to predict drag and heat transfer for flow over randomly rough surfaces. However, the current form of the ...

Abstract: Consider a semi-infinite, elastic body with its boundary a plane except for a solid circular cylinder which has its longitudinal axis perpendicular to the boundary plane. This paper contains ...

Abstract: Experiments have been conducted to measure the permeability and slip coefficient of seven porous tubes. They were made from fiberglass and nylon nettings with various wall thicknesses. Tests ...

Abstract: Theoretical predictions of wall shear stresses in unsteady turbulent flows in pipes are developed for all flow conditions from fully smooth to fully rough and for Reynolds numbers from

Abstract: Bayesian network models are seen as important tools in probabilistic design assessment for complex systems. Such network models for system reliability analysis provide a single probability of ...

Abstract: Climate nonstationarity and uncertainty raise important issues related to design and planning within the water sector. Participants in the planning process may not all agree on what climate assumptions and planning objectives ...
