this paper presents a k- turbulence model for simulation of steady current and itsinduced vortex shedding caused by the presence of an offshore pipeline. performance of the modelaround a circular cylinder above a wall with gap to diameter ratios of 0.1, 0.35 and 0.5 underdifferent flow regimes with reynolds numbers of 1500, 2500 and 7000 is studied. the flow field iscomputed with solving the re...

Climatic changes have decreased the stability of Gulf Stream (GS), increasing frequency at which its meanders interact with Mid-Atlantic Bight (MAB) continental shelf and slope region. These intrusions are thought to suppress biological productivity by transporting low-nutrient water otherwise productive edge Here we present evidence widespread, anomalously intense subsurface diatom hotspots in...

Recently it is found that Weyl anomaly leads to novel anomalous currents in the spacetime with a boundary. However, current suppressed by mass of charge carriers and distance boundary, which makes difficult be measured. In this paper, we explore possible mechanisms for enhancement currents. Interestingly, find can significantly enhanced high temperature, easier experimental detection. For free ...

During the last few years, a number of numerical boundary condition schemes have been used to study various aspects of the no-slip wall condition using the lattice Boltzmann method. In this paper, a modified boundary condition method is employed to simulate the no-slip wall condition in the presence of the body force term near the wall. These conditions are based on the idea of the bounce-back ...

in this paper, a numerical solution of an inverse non-dimensional heat conduction problem by spline method will be considered. the given heat conduction equation, the boundary condition, and the initial condition are presented in a dimensionless form. a set of temperature measurements at a single sensor location inside the heat conduction body is required. the result show that the proposed meth...
