A closed-form analytical model is developed for estimating the 3D boundary-layer-displacement thickness of an internal flow system at Sanal choking condition adiabatic flows obeying physics compressible viscous fluids. At this unique boundary-layer blockage induced fluid-throat and wall-friction persuaded occur a single sonic-fluid-throat location. The beauty novelty that without missing we could predict exact both 2D cases from known values inlet Mach number, index gas port diameter system....
The first law of thermodynamics reveals that all fluids are compressible, and the second entails to have positive viscosity. These established laws reaffirm possibilities occurrence Sanal flow choking in yocto yotta scale systems beyond [Kumar et al., “Discovery nanoscale cardiovascular system: Exact prediction 3D boundary-layer-blockage factor nanotubes,” Sci. Rep. 11, 15429 (2021); “Sanal choking: A paradigm shift computational fluid dynamics code verification diagnosing detonation...

The bed expansion characteristics of a fluidized containing bacterial granules have been studied. These biogranules were obtained from an anaerobic hybrid reactor, which uses (without carrier particle) in condition. settling velocity study has shown that the drag coefficient biogranule is greater than rigid particle at same Reynolds number. A new correlation based on this finding developed. demonstrated linear relationship exists between natural logarithm porosity and upflow superficial...

Noise reduction and control research are actively conducted as increasing noise problems compel the stringent requirement. Active (ANC) is constructively used in various applications to reduce low-frequency noise. In previous studies, ANC systems were designed based on experiments, requiring extensive effort for effective implementation. this paper, a real-time simulation computational aeroacoustics framework virtual-controller method presented. The aims investigate sound field changes...

Summary The main challenge of the immersed boundary approach is proper enforcement conditions on body interface without any spurious oscillations, which are induced by nongrid‐conforming configuration. In this study, a new sharp ghost‐cell method (IBM) proposed for obtaining solutions near with high order accuracy. idea “jump‐reduction” instead jump‐correction across combining flow reconstruction method. IBM, unknown values at three points, that is, ghost cell, and field point solved...
