Vibrations due to vortex shedding in the wake of a cylinder exposed current can create fatigue damage risers used by offshore industry bring oil and gas from sea floor platform or off-loading vessel. Extensive research is conducted this domain at Institut français du pétrole, several models are proposed predict life such pipes. The methods range simple modal calculations fully coupled analysis fluid-structure interaction resolution Navier-Stokes equations. Through Hydlines Project,...

This paper presents a general sensitivity equation method (SEM) for time dependent incompressible laminar flows. The formulation accounts complex parameter dependence and is suitable wide range of problems. SEM verified on problem with closed form solution. Systematic grid convergence studies confirm the theoretical rates in both space time. methodology then applied to pulsed flow around square cylinder. starts symmetrical vortex shedding transitions traditional Von Karman street (alternate...

CFD simulations of cross-flows along in-line and staggered tube bundles which emulate those encountered in the calandria CANDU-6 reactors are presented. The knowledge external wall temperature distributions around tubes is a major concern during normal off-normal operating conditions CANDU reactors. Calculations performed using FLUENT software with several turbulence models segregated Coupled algorithms. It observed that κ-based able to reproduce mean velocities bundles. In most cases,...

This paper presents a general Continuous Sensitivity Equation (CSE) method for computing first and second-order flow sensitivities the incompressible Navier–Stokes equations. The sensitivity equations boundary conditions are developed value parameters that do not affect geometry of computational domain. Applications thus restricted to simpler case parameters. solved by an adaptive finite element method. proposed methodology is verified on problem with closed form solution. code then applied...

We present the sensitivity Equation Method (SEM) as a complementary tool to adjoint based optimisation methods. Flow sensitivities exist independently of design problem and can be used in several non-optimization ways: characterization complex flows, fast evaluation flows on nearby geometries, input data uncertainties cascade through CFD code yield uncertainty estimates flow field. The Navier-Stokes equationssensitivity are solved by an adaptive finite element method.
