Efficient wall-modelled large eddy simulation of rotors using homogenized lattice Boltzmann methods

International Journal of Numerical Methods for Heat & Fluid Flow
Purpose Accurately capturing the dynamic forces acting on rotors as well as their wake effects presents a significant challenge for computational fluid dynamics due to high Reynolds numbers and a large range of spatio-temporal scales.

To Be or Not to Be Eutectic: Anomalous Glass Forming Ability Governed by Melt Structural Complexity. [PDF]

Adv Sci (Weinh)
Challenging the eutectic rule, congruently melting Ti–Cu alloys show greater glass‐forming ability than their eutectic counterparts. This arises from the congruent melt's structural complexity: higher cluster diversity and stronger inter‐cluster correlations from entropy–enthalpy competition.

Analytical solution of axi-symmetrical lattice Boltzmann model for cylindrical Couette flows [PDF]

, 2012
Analytical solution for the axi-symmetrical lattice Boltzmann model is obtained for the low-Mach number cylindrical Couette flows. In the hydrodynamic limit, the present solution is in excellent agreement with the result of the Navier-Stokes equation ...

A thermal lattice Boltzmann model for micro/nano-flows [PDF]

, 2008
The dynamic behavior of charged micro and nanofluids plays a crucial role in a large variety of industrial and biological processes. Such dynamic behavior is characterized by the simultaneous occurrence of several competing mechanisms, such as ...

Matrix lattice Boltzmann reloaded [PDF]

, 2011
The lattice Boltzmann equation has been introduced about twenty years ago as a new paradigm for computational fluid dynamics. In this paper, we revisit the main formulation of the lattice Boltzmann collision integral (matrix model) and introduce a new ...
