[00901] Effect of porous layer fitted on a floating bridge in mitigating waveload

  • Session Date & Time : 3D (Aug.23, 15:30-17:10)
  • Type : Contributed Talk
  • Abstract : Scattering of oblique water waves by a floating bridge with porous wall fitted on its vertical sides is studied. Significant changes are noticed in wave reflection due to changes in porosity. It is observed that as the porosity increases, the values of the reflection coefficient decrease. The behavior of various parameters, such as depth, porous wall width, porosity and angle of incidence, on the reflection coefficient are also carried out.

[01457] Evaporation and the coffee-ring effect for non-circular droplets

  • Session Date & Time : 3D (Aug.23, 15:30-17:10)
  • Type : Contributed Talk
  • Abstract : Diffusion-limited evaporation of liquid droplets is commonplace in industrial applications such as microscale patterning and Q/OLED production. However, beyond simple geometries, there are few analytical solutions. Here, we derive asymptotic results for the evaporative flux of a weakly non-circular droplet and demonstrate how these may be used to find the ‘coffee ring’ for large droplets, with excellent agreement to numerical simulations. Then, we show how the mathematical framework may be extended to polygonal drops.

[00331] Mathematical modelling of fluid-particle interaction

  • Session Date & Time : 3D (Aug.23, 15:30-17:10)
  • Type : Contributed Talk
  • Abstract : Fluid-particle interactions are fundamental to many problems in industry and biology, for example aircraft icing, where ice adheres to aircraft, and the movement of drugs/thrombi in blood. Mathematical modelling and asymptotic methods can be used to reduce such problems to simple ODEs and PDEs which can be solved to reveal an intriguing variety of particle motions. Current work includes an ice particle submerged in water, and a particle in lubrication flow with application to blood.

[02040] Simulation of landslide-generated waves using non-hydrostatic numerical model

  • Session Date & Time : 3D (Aug.23, 15:30-17:10)
  • Type : Contributed Talk
  • Abstract : The reduced two-layer non-hydrostatic (NH-2LR) numerical model is developed and used to study landslide-generated waves. The NH-2LR model is validated using analytical solutions and laboratory experiments. Simulations involves landslide motions on a flat bottom as well as over a sloping beach. The effects of dispersion and non-linearity are then investigated; dispersion is important in the early generation and propagation of landslide-generated waves, whereas non-linearity has a significant influence on maximum run-up.

[02148] A comparative study on scattering of water waves by barriers of various kinds.

  • Session Date & Time : 3D (Aug.23, 15:30-17:10)
  • Type : Contributed Talk
  • Abstract : The present study outlines the mathematical and computational details needed to compute the solutions on the scattering of surface water waves by a finite dock, thin rectangular elastic plate and circular elastic plate in finite depth water. The boundary value problem is handled for solutions analytically using a matched eigenfunction expansion . Various physical quantities associated with the scattering problems are studied for various values of wave and structural parameters. A selection of results are given to illustrate the variations of scattering coefficients and to compare with existing solutions.
