RISFrom the Phan–Thien–Tanner/Oldroyd-B Non-Newtonian Model to the Double Shear Thining Rabinowisch Thin Film Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, an asymptotic expansion is used to derive a description of Phan–Tien– Tanner (PTT)/Oldroyd-B flows in the thin film situation without the classical “upper convective maxwell”(UCM) ...
An Average Flow Model of the Reynolds Roughness Including a Mass-Flow Preserving Cavitation Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An average Reynolds equation for predicting the effects of deterministic periodic roughness, taking Jakobsson, Floberg, and Olsson mass flow preserving cavitation model into account, is introduced ...
Finite Element Analysis of a Contact With Friction Between an Elastic Body and a Thin Soft Layer
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: When studying a mechanical system involving contact between two bodies such as a disc and brake pad system, finite element simulations are often used to predict the phenomena involved. However, ...
The Impact of the Cavitation Model in the Analysis of Microtextured Lubricated Journal Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we analyze the impact of the cavitation model on the numerical assessment of lubricated journal bearings. We compare results using the classical Reynolds model and the so-called ...
