in this paper, a 3d stochastic model has been presented to predict the coating thickness and porosity in a thermal spray coating process. different values of processing parameters were obtained. the model was developed on the basis of prescribed rules in calculating the splat size during the impact of individual droplets on the surface of the substrate. due to the thermal stresses produced duri...

Abstract: Cooling slope-casting processing is a relatively new technique to produce semisolid cast feedstock for the thixoforming process. Simple equipment, ease of operation, and low processing costs are the main advantages of this process in comparison with existing processes such as mechanical stirring, electromagnetic stirring, etc. The processing parameters of cooling slope casting are...

A full vector radiative transfer model for vertically inhomogeneous plane–parallel media has been developed by using the successive order of scattering approach. In this model, a fast analytical expansion of Fourier decomposition is implemented and an exponent-linear assumption is used for vertical integration. An analytic angular interpolation method of post-processing source function is also ...

In the domain of vineyard precision spraying research, one of the most important objectives is to minimize the volume of phytosanitary products ejected by a sprayer in order to be more environmentally respectful with more effective vine leaf treatments. Unfortunaltely, even if lot of works have been carried out at a parcel scale, mainly on losses caused by drift, less works have been carried ou...
