In recent years, unmanned vehicles have intensively been developed to reduce human dangers for marine applications. Predicting the hydrodynamic coefficients of an autonomous underwater vehicle is important during the vehicle’s design phase. In other words to design an AUV, one must clarify its maneuverability and controllability based on a mathematical model. The mathematical model contains var...
UNLABELLED The objective of this study was to determine the influence of hydrodynamic pressure processing (HDP) and aging on the processing characteristics and final meat quality of moisture-enhanced pork loins. Boneless pork loins (n = 24) were split into 3 portions and assigned treatments: control (non-HDP treated, brine-injected), HDP treated before brine-injection, or HDP treated after brin...
A framework of analogy between wiretap channels (WTCs) and state-dependent point-to-point channels with noncausal encoder channel state information (referred to as Gelfand-Pinker channels (GPCs)) is proposed. A good (reliable and secure) sequence of wiretap codes is shown to induce a good (reliable) sequence of codes for a corresponding GPC. Consequently, the framework enables exploiting existi...
We demonstrate theoretically and experimentally that injection of momentum in a region surrounding an object microscale flow can yield both “cloaking” conditions, where the field outside cloaking is unaffected by object, “shielding” hydrodynamic forces on are eliminated. Using field-effect electro-osmosis as mechanism for momentum, we present theoretical framework analytical solutions range geo...
Pore-scale CFD simulations of clay mobilization in natural porous media due to fresh water injection
The present work investigates mechanisms of permeability impairment as a result low-salinity fluid injection into brine-saturated porous media containing dispersible clays. We computational dynamics model at the pore-scale to simulate detachment, migration and straining fine particles in media. uses an immersed boundary method motion clay fines fluid. In addition hydrodynamic forces, we Derjagu...
A new approach extracting multi-parametric hydrodynamic reductions for the integrable hydrodynamic chains is presented. The Benney hydrodynamic chain is considered.
Macroalgae use flexibility and reconfiguration, i.e. the alteration of shape, size and orientation as water velocity increases, to reduce the hydrodynamic forces imposed in the wave-swept rocky intertidal zone. Quantifying the effects of flexibility on hydrodynamic performance is difficult, however, because the mechanisms of reconfiguration vary with water velocity and the relationship between ...
A numerical procedure to determine the equivalent hydrodynamic dispersion coefficients and Péclet number (Pe) of a fractured rock is presented using random walk particle tracking method. The geometrical effects of fracture system on hydrodynamic dispersion are studied. The results obtained from the proposed method agree well with those of empirical models, which are the scale-dependent hydrodyn...
