Probabilistic Assessment of Space Nuclear Propulsion System Nozzle [PDF]
Volume 3C: General, 1993 Uncertainties associated with the design parameters of the Space Nuclear Propulsion System (SNPS) nozzle such as geometry, boundary conditions, material behavior, thermal and pressure loads, etc. are considered to assess its reliability. Preliminary assessment of the reliability is performed using NESSUS (Numerical Evaluation of Stochastic Structures ...

Effect of working pressure and spacing of nozzles on the quality of spraying distribution
Crop Protection, 2022 Abstract The correct placement of the crop protection product on the target depends on the adequate distribution provided by the spray nozzles. In this research, the objective was to verify the influence of the working pressure and spacing between nozzles on the quality of the spray distribution.

Advanced Engineering Materials, EarlyView.This study demonstrates an efficient recycling route for out‐of‐spec AlSi10Mg atomized powders through compaction and arc remelting followed by suction casting. By correlating compaction load, cooling rate, and resulting microstructure, we show that intermediate pressures (50–80 kN) and rapid cooling refine dendrites, reduce porosity, and enhance ...

Advanced Engineering Materials, EarlyView.High‐temperature interactions between low‐sulfur Al‐killed Mn–B steel and MgO–C refractories (0 and 50 wt% recyclates) are studied via finger immersion tests (1600 °C). Surface‐active elements influence infiltration. MgO/CaS layer forms, along with spinel and calcium silicate.
