The use of passive integrated transponder (PIT) tags in ecological studies is increasingly common, but evaluations of their performance and range of application in the field are still emerging. Here, we compare habitat unit–scale abundance estimates of PITtagged juvenile coho salmon Oncorhynchus kisutch and steelhead O. mykiss derived from multiple-pass surveys with a submersible pole-mounted P...

this paper presents the effect of high viscosity oil and two-phase foamy-oil flow on the performance of a single stage centrifugal pump. as a part of this, the applicability of a pipe viscometer to determine the foamy oil viscosity is investigated. unlike previous studies, a sealed fluid tank is used in a closed flow loop to allow conditioning the two-phase mixture to create foamy-oil. furtherm...

the performance of the electric submersible pump (esp) significantly affected by gas void fraction (gvf). thus, using of a rotary gas separator (rgs) is a suitable solution for this issue. the performance of the rgs is function of different parameters such as geometry of impeller, rotating speed, boundary conditions, media viscosity and gvf. in this study, the influences of gvf, viscosity, and ...

Abstract This paper establishes the computational fluid dynamics models of marine submersible buoy system. The use incompressible Navier-Stokes equations, Renormalization-Group (RNG) turbulence model and fractional areas/volume obstacle representation method. Using lumped mass mothed to simulate anchor line power supply cable. result show that great tension forces increase occurs at moment when...
