TL;DR: In this article, the authors present a methodology for development of reduced order models that can be used to estimate the fluid flow and the flow forces in hydraulic valves, as a function of a reduced number of critical dimensional and material parameters.

TL;DR: In this paper, a series of CFD simulations of the cavitating flow through a ball check valve were performed in order to obtain the mass flow rate through the valve under different operating conditions, inducing or preventing the appearance of cavitation by conveniently adjusting the pressure level on the valve outlet port.

TL;DR: In this article, the effects of surface roughness on the laminar fluid flow through annular microchannels were investigated by means of numerical simulation, and a method was proposed to take into account the roughness effects in the calculation or simulation of the fluid flow, based on the classical viscous flow equations.

TL;DR: In this article, the authors discuss developments in the area of anti-lock braking control for full electric vehicles, and the main contributions of the paper are the development and experimenta...

TL;DR: In this paper, the results of experimental investigations obtained from proving ground tests of all-wheel drive all-electric vehicles (EVs) with individually controlled wheel drive are presented, where the authors evaluate the brake performance for three different configurations: hydraulic ABS, regenerative ABS only on the front axle, blended hydraulic and regenerative braking on the rear axle, and hydraulic ABS on the rule-based controller.
