Thermal Elastohydrodynamic Lubrication Analysis of Bevel Gear based on a Finite Line Contact Model
In order to study the thermal elastohydrodynamic lubrication mechanism of bevel gears, based on the theory of elastohydrodynamic lubrication, a finite line contact model is established and the thermal elastohydrodynamic characteristics of straight bevel ...

Oil film interferometry in high Reynolds number turbulent boundary layers [PDF]
There is continuing debate regarding the validity of skin friction measurements that are dependent on the functional form of the mean velocity profile, for example, the Clauser chart method.

Running-in wear modeling of honed surface for combustion engine cylinder liners [PDF]
The texture change during running-in alters the performance and efficiency of a tribo-mechanical system. During mass production of cylinder liners, a final finishing stage known as ‘‘plateau honing’’ is commonly added to reduce the running-in wear ...

The nanostructure, size, and function of mRNA‐loaded lipid nanoparticles are evaluated before drying, within polymer microneedles, and after rehydration. The results reveal the polymer and LNP loadings required to recover nanostructure and preserve the delivery performance in dry‐state formulations.

Evaluation of water film by reynolds' equation in deep drawing using high-pressured water jet [PDF]
The authors had proposed a deep drawing method using high-pressured jet waters as lubricant. This method aimed to suppress the usage of oil or other chemical lubricants, which might require some additional processes for lubricant removal and become a ...

Abstract Currently, in order for the Chinese naval forces to achieve strategic transformation and move towards the deep blue sea, there is an urgent need to enhance the capabilities of far-sea operations. Most naval ships in various countries use gas turbines as the power source, and the bearings supporting the transmission shafts of gas

Exploring Pb‐Chelation Chemistry in the Crystallization Dynamics of Halide Perovskites
A mechanism of how Pb‐chelation chemistry governs coordination geometry and initial nucleation behavior at the precursor level of halide perovskite, by regulating the deprotonation state of a chelating additive, is elucidated. This allows for innovative reaction‐system design principles that promote coherent growth while suppressing defect formation in
