Metaphoric optical computing for fluid dynamics [PDF]
SPIE Proceedings, 2005 We present theoretical and numerical evidence to show that self-defocusing nonlinear optical propagation can be used to compute Euler fluid dynamics and possibly Navier-Stokes fluid dynamics. In particular, the formation of twin vortices and the K rm n vortex street behind an obstacle, two well-known viscous fluid phenomena, is numerically ...

CFD/RBD Numerical Simulation Research on the Process of Buried Aviation Weapon Launch [PDF]
Hangkong bingqi, 2021 Because of its special configuration, the flying wing layout aircraft shows a big difference in performance from conventional aircraft. Embedded weapon cabin can help fighters improve stealth performance, but the door interference and the flow under the ...

Computational fluctuating fluid dynamics [PDF]
ESAIM: Mathematical Modelling and Numerical Analysis, 2010 This paper describes the extension of a recently developed numerical solver for the Landau-Lifshitz Navier-Stokes (LLNS) equations to binary mixtures in three dimensions. The LLNS equations incorporate thermal fluctuations into macroscopic hydrodynamics by using white-noise fluxes.

Exact pressure evolution equation for incompressible fluids [PDF]
AIP Conf.Proc.1084:224-229,2009, 2008 An important aspect of computational fluid dynamics is related to the determination of the fluid pressure in isothermal incompressible fluids. In particular this concerns the construction of an exact evolution equation for the fluid pressure which replaces the Poisson equation and yields an algorithm which is a Poisson solver, i.e., it permits to time ...

Thermal Characterization of Eicosane/Graphite Nano-Composite-Based Phase Change Material [PDF]
Journal of Renewable Energy and Environment, 2023 Phase Change Materials (PCMs) have received much consideration as thermal energy storage systems due to their high storage capacity. However, their heat transfer rate is limited because of the low thermal conductivity.
