Wave propagation theory in offshore applications
A frequency-wavenumber-domain formulation is presented in this paper for calculation of the Green's functions and wave propagation modes in a stratified fluid body underlain by a layered viscoelastic soil medium. The Green's functions define the solid and fluid displacements and fluid pressures due to uniform disk loads acting in either the soil or fluid media. The solution is in the frequency ...
متن کاملTransport phenomena in Alcator C-Mod H-modes
Several interesting new results have come from studies of ICRF-heated, H-mode plasmas in Alcator C-Mod. Dimensionless scaling studies have found gyro-Bohm-like transport similar to that reported on other devices; however, the dependence on collisionality was surprisingly strong, with BτE ∼ ν∗−1. Despite high edge temperatures and strong edge pressure gradients, type I edge-localized modes (ELMs...
متن کاملElectromagnetic gyro-fluid simulations with BOUT++
Transport at the pedestal top is important for the inter-ELM pedestal dynamics. Linear gyrokinetic analysis of the pedestal during an ELM cycle on MAST has shown kinetic ballooning modes to be unstable at the knee of the pressure profile and in the steep pedestal region whilst microtearing modes (MTMs) and electron temperature gradient modes (ETGs) dominate in the shallow gradient region inboar...
متن کاملHydroelastic Vibration of a Circular Diaphragm in the Fluid Chamber of a Reciprocating Micro Pump
Reciprocating diaphragm micro-pumps are the most common type among indirectly–driven micro-pumps. They operate by reciprocating the diaphragm with associated check valves. This paper addresses the Hydroelastic vibration of circular elastic diaphragm interacting with the incompressible and inviscid liquid inside the cylindrical chamber with a central discharge opening. Taking into account axisym...
متن کاملQuantitative Comparisons of DIII–D Turbulence Measurements to Gyro-Kinetic and Gyro-Fluid Turbulence Simulations
Experimental turbulence and transport characteristics in DIII–D plasmas have been compared with similar quantities calculated from gyro-kinetic and gyro-fluid turbulence simulations. Turbulent radial correlation lengths ∆r from DIII–D L–mode plasmas scale as 5 to 10 ρs (ρs = ion gyro-radius evaluated using the electron temperature) and are independent of the poloidal magnetic field. Comparisons...
