A new flow field mathematical model is proposed to describe accurately the flow field structure and calculate the static characteristics of the pilot stage in a deflector jet servo valve(DJSV). The flow field is divid...
An entrainment defect(also known as a double oxide film defect or bifilm) acts a void containing an entrapped gas when submerged into a light-alloy melt, thus reducing the quality and reproducibility of the final cast...
The complete numerical solution of line contact thermal elastohydro dynamic lubrication, the complete three dimensional temperature field and the dis tribution of traction drag force in the contact zone under differen...
