One major disadvantage of many arc welding processes is welding-induced residual stresses and distortions. The non-uniform heating and cooling during arc welding result in non-uniform expansion and contraction of the ...

This paper presents a novel model to simulate the ow-current characteristic curve of an electro-hydraulic servo valve in steady state condition. This characteristic curve has three major zones: dead zone, linear zone ...

This paper describes a design methodology for ducted propellers operating in a non-uniform wake eld. An improved lifting line model is used to represent propeller blades where more realistic slipstream deformation behind ...

Decoupling of dynamic equations in robotic mechanisms has attracted many researchers in the recent years. This kind of decoupling can be achieved by modifying the original kinematic structure through the use of counterweights ...

In this paper, a compressible, one-dimensional and two-phase ow is analytically modeled by using a homogeneous classical nucleation rate equation in a Laval nozzle. For droplet growth calculations, the heat transfer ...
