The aerodynamic properties of seeds and grains are fundamental knowledge for the dimensioning machinery used in processing, storage, harvest post-harvest operations. objective this study was to determinate two quinoa cultivars within different moisture contents. BRS Piabiru Real determined their physical (dimensions density), terminal velocity, drag coefficient Reynolds number, seven content (1...

Current driven domain wall motion in curved Heavy Metal/Ferrimagnetic/Oxide multilayer strips is investigated using systematic micromagnetic simulations which account for spin-orbit coupling phenomena. Domain velocity and characteristic relaxation times are studied as functions of the geometry, curvature width strip, at out angular momentum compensation. Results show that walls can propagate fa...

In present work, we report an experimental setup that has been developed to characterize highly under-expanded helium and nitrogen jets confined in a vacuum chamber. The evolution of Zone Silence (ZOS) is studied found experimentally measured ZOS for are agreement with empirical relation mathematical model. velocity the jet inside using time flight (TOF) probe without skimmer. We able measures ...

We present results of the solution of hydrodynamic equations of a two-component radiatively driven stellar wind with an inclusion of the frictional force. The temperature of the wind is assumed to be equal to the effective temperature of the star. We found that for the case of late B stars the stellar wind does not decouple, but its terminal velocity is lowered with respect to the one-component...

according to flexibility of pneumatic conveying systems with respect to other types of transmission systems, this system has wide application in industry and agriculture processes. one important application of this system is in the loading and unloading tankers and powdery bulk materials such as trucks carrying cement, plaster and sand. conveying efficiency is associated with pressure, which in...
