[01362] Nanoparticle Shape Effect On a Sodium–Alginate Based Cu–nanofluid Under a Transverse Magnetic Field

  • Session Time & Room : 5D (Aug.25, 15:30-17:10) @D404
  • Type : Contributed Talk
  • Abstract : Sodium-alginate based nanofluids represent a new generation of fluids with improved performances in terms of heat transfer. This work examines the influence of the nanoparticle shape on a non–Newtonian viscoplastic Cu–nanofluid pertaining to this category. In particular, a stretching/shrinking sheet subjected to a transverse magnetic field is considered. The proposed Cu–nanofluid consists of four different nanoparticles having different shapes, namely bricks, cylinders, platelets, and blades dispersed in a mixture of sodium alginate with Prandtl number Pr  =  6.45. Suitable similarity transformations are employed to reduce non–linear PDEs into a system of ODEs and these equations and related boundary conditions are solved numerically by means of a Runge–Kutta–Fehlberg method. Moreover, analytical solutions are obtained through the application of a MAPLE built–in differential equation solver "Dsolve". The behavior of prominent parameters against velocity and temperature is analyzed. It is found that the temperature increases for all shapes of nanoparticles with the viscoplastic parameter and the Eckert number.

[00971] Quantify the classicality of quantum states

  • Session Time & Room : 5D (Aug.25, 15:30-17:10) @D404
  • Type : Contributed Talk
  • Abstract : In this talk, I will first introduce classicality and quantumness in a given quantum state. As quantumness speeds up quantum algorithms, gauging the "non-quantumness" or so-called "classicality" becomes an important task. Next, I will demonstrate using descent flow on smooth manifolds to resolve the issue. Finally, I will exhibit several numerical experiments to clarify whether our proposed method is reliable and applicable.

[00321] Modeling of hydromagnetic unsteady flow over a upright plate using Pseudospectral method

  • Session Time & Room : 5D (Aug.25, 15:30-17:10) @D404
  • Type : Contributed Talk
  • Abstract : This study looks at the effects of a crosswise magnetic field along with thermal radiation proceeding the unsteady two-dimensional magneto hydrodynamic viscous flow, electrically insulating, and Newtonian fluid across an upright plate next to a Darcian rule. For governing equations, Pseudospectral Method is used. In this inquiry, the governing non-linear, coupled partial differential equations are decoded using Pseudospectral scheme that is reliable, effective, and has undergone substantial validation. The technique's precision and efficacy are proven.

[00993] The effect of extended coupling in transport system

  • Session Time & Room : 5D (Aug.25, 15:30-17:10) @D404
  • Type : Contributed Talk
  • Abstract : Totally Asymmetric Simple Exclusion Process is a stochastic model to recognize the nature of non-equilibrium transport systems. Inspired by the vehicular traffic phenomena, we have actuated a new kind of coupling rule on transport dynamics. The impact of the designed dynamics on system properties has been analyzed over phase diagrams, phase transitions, finite size effect, and shock position. The calculated numerical results from mean-field theory are verified through the ground of Monte Carlo simulation.

[02430] Hessian geometric derivation of macroscopic thermodynamic uncertainty relations (TUR)

  • Session Time & Room : 5D (Aug.25, 15:30-17:10) @D404
  • Type : Contributed Talk
  • Abstract : The recently developed Hessian geometry of force and flux spaces in chemical reaction networks provides a geometric derivation of TUR. The relations are obtained from a comparison of two Riemannian metric tensors - one characterizes the pseudo entropy production and the other the current fluctuations. This geometry yields a characterization of the error term as the norm of a linear subspace component of the flux vector and thus characterizes the fluxes where TUR become equalities.
