Article
The optimum periodic surface grooves that provide the highest load-carrying capacity (LCC) in parallel flat surface bearings are obtained using mathematical optimization methods. Results show that the optimum groove geometry is a function of the aspect ratio. For small aspect ratios the optimum grooves have an elongated “heart-like” shape and for h...

A theoretical analysis of a hydrodynamic thrust bearing with a flexible-pad design is presented. The flexibility of pads improves the load-carrying capacity (LCC) of the bearing for a wide range of loading conditions by providing an adaptive surface deformation mechanism. To accurately predict the behavior of flexible-pad thrust bearings, an approp...
Article
The optimum shape of hydrodynamic film that provides the greatest load-carrying capacity (LCC) in sectorial-shape thrust bearings is obtained using sequential quadratic programming (SQP). Also presented are three suboptimum solutions for special cases of 2D step profile, constant film thickness in the radial direction and constant film depth with q...

a b s t r a c t The improvement of energy efficiency and environmental performance of buildings is considered a major priority worldwide. New building regulations have an explicit orientation toward low-emission and energy-efficient designs. However, the optimal design of residential buildings should consider multiple, and usually competitive, obje...

A comprehensive mathematical model for the cathode catalyst layer (CL) of a proton exchange membrane fuel cell (PEMFC) is developed to investigate its performance, which is determined by activation overpotential. Numerous cathode CL parameters such as the saturation and eight structural parameters, namely, ionomer film thickness covering each agglo...

The implementation of the mass-conservative cavitation algorithm, as derived by Elrod, requires an automatic setting of a binary switch function that delineates the full-film and cavitation zones. Abrupt changes associated with this function often causes convergence and instability issues. A method is that which improves numerical instability and o...

In this study, the homotopy analysis method (HAM) is used to obtain an approximate analytical solution for geometrically non-linear vibrations of thin laminated composite plates resting on non-linear elastic foundations. Geometric non-linearity is considered using von Karman’s strain–displacement relations. Then, the effects of the initial deflecti...

Microscale mechanical self-adaptive bearings are a recent development in the field that offer promising features such as enhanced load-carrying capacity compared to conventional bearings. This study aims to improve the load-carrying capacity of these bearings by introducing novel deformable groove designs. The objective is to find the optimum groov...
Article
Self-adaptive, microscale grooves improve the load-carrying capacity of the lubricated surfaces by providing a “flexible surface texturing.” These grooves use mechanical deflection to change the surface texture based on the loading condition. To accurately predict the behavior of a self-adaptive groove, the surface deformation is computed by treati...
