The steady oblique path of buoyancy-driven disks and spheres [PDF]

open access: yes, 2012
We consider the steady motion of disks of various thicknesses in a weakly viscous flow, in the case where the angle of incidence $\alpha$ (defined as that between the disk axis and its velocity) is small.

Through-flow effects on Nusselt number and torque coefficient in Taylor-Couette-Poiseuille flow investigated by large eddy simulation

open access: yesJournal of Thermal Science and Technology, 2016
Flow in a concentric annular passage with a rotating inner cylinder, which is called Taylor-Couette flow, is important in industrial applications, such as electric motor which requires not only effective cooling of rotating shaft but also saving power ...

Toroidal modeling of penetration of the resonant magnetic perturbation field [PDF]

open access: yes, 2013
A toroidal, quasi-linear model is proposed to study the penetration dynamics of the resonant magnetic perturbation (RMP) field into the plasma. The model couples the linear, fluid plasma response to a toroidal momentum balance equation, which includes ...

Novel electric power steering control strategies of commercial vehicles considering adhesion coefficient

open access: yesAdvances in Mechanical Engineering, 2020
The steering resistance torque of commercial vehicles on low adhesion pavement is greatly reduced. Therefore, while driving on low adhesion pavement, the use of traditional EPS control strategies without considering adhesion coefficient will lead to ...
