Vortex-induced vibration (VIV), a type of flow-induced vibration, is relatively new means generating clean energy. The present study aims to quantify the flow-power extraction using elastically mounted elliptical cylinders different aspect ratios (AR). power process modeled linear damper attached moving cylinder. mass ratio vibrating structure (m*) kept constant at 10, and Reynolds number taken as 100 for 2D numerical simulation. cylinder varies from 0.10 1.00 (circular cylinder), damping...
We numerically investigate vortex-induced vibration of a cooled circular cylinder in the presence thermal buoyancy. employ an in-house fluid-structure interaction solver based on sharp-interface immersed boundary method. The is elastically mounted and free to vibrate transversely flow direction. surface prescribed at temperature lower than that fluid, gravity aligned opposite Numerical simulations are carried out for following parameters: Reynolds number, Re = 150, Prandtl Pr 7.1, Richardson...
The effects of confinement on vortex-induced vibration (VIV) a circular cylinder (diameter D) and its flow power extraction capability are presented. A two-dimensional numerical study is performed VIV inside parallel plate channel height H at Reynolds numbers 100 150. blockage ratio (b = D/H) varied from 1/4 to 1/2. elastically mounted with spring such that it can only vibrate transversely the flow. It has fixed non-dimensional mass (m*) 10. energy process modeled as damper (damping ζ)...
We report the development of an in-house fluid-structure interaction solver and its application to vortex-induced vibration (VIV) elastically mounted cylinder in presence thermal buoyancy. The flow utilizes a sharp interface immersed boundary method, present work, we extend it account for buoyancy using Boussinesq approximation couple with spring-mass system VIV. one-way coupling explicit time integration scheme is computationally efficient. benchmark code verifications natural convection,...
The effect of cross-flow thermal buoyancy on vortex-induced vibration (VIV) a circular cylinder is numerically investigated. An in-house fluid-structure solver based the sharp-interface immersed boundary method employed. kept in uniform flow stream and mounted elastically such that it constrained to move transverse direction flow. surface heated at prescribed temperature, imposed Simulations are performed for following parameters: Reynolds number Re = (50, 150), Prandtl Pr 7.1, mass ratio m...
Fluid-structure interaction (FSI) of thin flexible plates involving large-scale flow-induced deformation is presented as a potential heat transfer enhancement technique. An in-house, strongly-coupled FSI solver employed in which flow and structural solvers are based on sharp-interface immersed boundary finite-element methods, respectively. Twin deformable heated channel considered with laminar pulsating flow. Numerical simulations show that the vortex ring past sweeps higher sources...
Ocular injuries from blast have increased in recent wars, but the effectiveness of eye armor, developed for ballistic and laser protection, preventing remains unknown. The severity distance tertiary care facility injury site means that often patients are unable to recount event, witnesses unavailable. These limitations hinder clinical studies armor. role following parameters unknown designing armor: underwash between armor face; clearance compliance armor; angle incidence wave; contact force...
