[01046] Flow past a mounted wedge: The three fold structure

  • Session Time & Room : 2C (Aug.22, 13:20-15:00) @D401
  • Type : Contributed Talk
  • Abstract : This talk is concerned with the simulation of flow past a wedge mounted on a wall for channel Reynolds number $Re_c = 6873$ in accelerated flow medium. All three stages of vortex shedding for the accelerated flow, leading to the exceedingly intricate three-fold structure has been captured very accurately. Transition to turbulence have also been resolved which is indicated by the existence of coherent structures.

[00344] Forced convection from an isothermal square cylinder in shear flow

  • Session Time & Room : 2C (Aug.22, 13:20-15:00) @D401
  • Type : Contributed Talk
  • Abstract : Forced convection from an uniformly heated square cylinder placed in linear shear flow of constant properties fluid is numerically investigated at Reynolds number, Re=100, shear rate, K=0.0-0.2 and Prandtl number, Pr=0.5. The two-dimensional mathematical equations of flow motion and energy are solved using a higher order compact (HOC) finite difference scheme on Cartesian grids. The effect of K is investigated on flow and thermal fields in terms of isotherm patterns, Nusselt number distributions etc. The resulting vortex shedding phenomena behind the cylinder is detected and thermal field is determined.

[01490] RANS modelling of OWC device over the sloping seabed

  • Session Time & Room : 2C (Aug.22, 13:20-15:00) @D401
  • Type : Contributed Talk
  • Abstract : The hydrodynamics of the oscillating water column device placed over the sloping seabed under the influence of irregular incident waves is studied. Reynolds-Averaged Navier-Stokes equations (RANS) with a modified k − w turbulence model was used and the air-water interface was tracked using a volume-of-fluid (VOF) approach. The results demonstrate that the amplitude of the inward and outward velocities via the orifice, free surface elevations, and flow characteristics are greater for higher significant wave heights.
