[00064] Immersed boundary simulations of fluid shear-induced deformation of a cantilever beam
- Session Date & Time : 2E (Aug.22, 17:40-19:20)
- Type : Contributed Talk
- Abstract : This work considered a 2D model of rectangular cantilever beam immersed in a channel filled with viscous, incompressible fluid, where one end of beam is fixed to the channel wall, bending in response to shear flow. IB method was employed to simulate fluid–structure interaction. Effect of physical parameters of the problem — stiffness , height of cantilever , flow velocity was investigated, and simulation results were qualitatively compared with respect to linear beam theory.

[01087] Ferrohydrodynamic Mixed Convective Flow of a Rotating Disk with Vertical Motion
- Session Date & Time : 2E (Aug.22, 17:40-19:20)
- Type : Contributed Talk
- Abstract : A mathematical model of an electrically non-conducting nano-ferrofluid over a rotating disk subject to vertical disk motion and low oscillating magnetic field with heat transfer is framed. The coupled ferrohydrodynamic equations of motion and the magnetization equation is solved using finite difference method with collocation technique and artificial intelligence algorithm. Novel results are obtained for ferroparticle concentration and magnetization parameter subject to entropy optimization.

- Abstract : This talk concerns the global approximate controllability of incompressible Newtonian fluids driven by a physically localized and degenerate interior control. By introducing transported Fourier modes as building blocks, we act on the planar Navier--Stokes system via four scalar controls that depend only on time and appear as coefficients in an effectively constructed driving force supported in a given subdomain. The four unknown parameters can be computed by merely solving a linear transport controllability problem.

[00115] Nanoparticle shape effect of hybrid nanofluid inside a U-shaped enclosure
- Session Date & Time : 2E (Aug.22, 17:40-19:20)
- Type : Contributed Talk
- Abstract : The nanoparticle shape effect on the natural convection of copper-alumina/water hybrid nanofluid inside a U-shaped enclosure is presented. The governing equations are transformed into dimensionless form. A weighted residual Galerkin triangular finite element method is used to solve the problem numerically. The isotherms and streamlines of the fluid are presented with Rayleigh numbers of $10^4$ to $10^6$. The blade nanoparticle produces the highest heat transfer rate, while the sphere is the lowest.

[00683] Linearized Saint-Venant Equation with Lateral Inflow in a Finite Channel
- Session Date & Time : 2E (Aug.22, 17:40-19:20)
- Type : Contributed Talk
- Abstract : We present a solution for linearized Saint-Venant equations with uniformly distributed lateral inflow for a finite rectangular channel. The discharge is presented as the convolution of the distributed lateral inflow and lateral channel response function. We study the behavior of lateral channel response function for different parameters. To find discharge at any location of a channel for a given channel width, the choice of reference discharge and slope of the channel play a significant role.
