Design and Fabrication of Pressure-Compensating Compliant Tubes
Different fabrication methods are evaluated for producing pressure-compensating tubes for use in low-pressure drip irrigation systems. Such devices would allow drip irrigation systems to operate at driving pressures much lower than those required by current available technology, allowing for cost and water savings in developing nations. Fabrication methods explored consist mainly of molding of ...
متن کاملComputational studies of resonance wave pumping in compliant tubes
The valveless impedance pump is a simple design that allows the producion or amplification of a flow without the requirement for valves or impellers. It is based on fluid-filled flexible tubing, connected to tubing of different impedances. Pumping is achieved by a periodic excitation at an off-centre position relative to the tube ends. This paper presents a comprehensive study of the fluid and ...
متن کاملFlux Tubes in Effective Field Theory
Quark-antiquark bound states are examined in the long-range strongcoupling limit with the minimal area law of lattice gauge theory assumed as input. Matrix element relations are established which in the effective theory obtain dynamical equations equivalent to a formulation of the flux-tube model.
متن کاملNonlocal theory of area-varying waves on axisymmetric vortex tubes
Area and axial flow variations on rectilinear vortex tubes are considered. The state of the flow is characterized by two dependent variables, a core area, and an azimuthal circulation per unit length, which vary in time and in distance along the length of the tube. Nonlinear integrodifferential equations of motion for these variables are derived by taking certain integrals of the vorticity tran...
متن کاملTheory-aware Explanation Support for Standard-compliant Scenario Building
Nowadays standard technologies play important roles in enhancing sharability, reusability and interoperability of learning contents. However, there is a lack of pedagogical justification of the contents implemented with the standards. This paper discusses the standardcompliance of our ontology-based modeling framework and how the framework gives theoretical justification to standard-compliant l...
