Sistem pipa bawah laut/riser yang dipasang pada kedalaman tertentu di laut berkemungkinan mengalami kegagalan akibat beban hidrodinamik seperti gelombang dan arus, salah satunya dapat menyebabkan terjadinya Vortex Induced Vibration (VIV). Jika hal ini tid... see more

Reduction of cylinder surface resistance can be accomplished by modifying roughness. The surface roughness structure is one of the important parameters which greatly affects the flow of fluid through the cylinder surface. Fluid flow forms a vortex flow pa... see more

Numerical simulations of the axisymmetric laminar flow characteristics past a rigid sphere impulsively started are presented for Reynolds numbers from 20 to 1000. The results are obtained by solving the complete time dependant Navier-Stokes equations in v... see more

In this paper we consider the effects of vortex diffusion in two paradigmatic inhomogeneous physical situations; radial heat flow between two concentric cylinders, and vortex decay in a finite cylindrical container. Diffusion effects may strongly modify t... see more

Along with technological development and the increase in human population, the electricity needs are increasing every year. However, 94% of power plant in Indonesia still using fossil fuels that are pollutant and non-renewable. In addition, NASA said that... see more

The experimental study has been performed on two flexible free-hanging circular cantilevers in tandem configurations subjected to uniform cross-flows. The experiment was intended to investigate the time-dependent forces characteristics acting on the cylin... see more

In this paper, a system of field equations is written, able to describe the superfluid ransition, under the hypothesis that the liquid is at rest, in the presence of heat flux and of a small production of vortices below the superfluid transition temperatu... see more

AbstrakPengukuran dilakukan untuk menentukan batas fasa superkonduktor/normal pada struktur makroskopik dan struktur mikroskopik superkonduktor hibrid Pb/Al. Struktur terdiri lapisan Al setebal 50 nm dan 50 nm lapisan Pb yang (dideposisi di atas lapisan A... see more
