Large-eddy simulations of flow and heat transfer around a low-Mach number turbine blade

Modeling of wall bounded flows and conjugate heat transfer (CHT) is known to be a challenging task for Large-Eddy Simulation (LES). In the boundary layers, the inertial and dissipative scales have similar sizes, which implies relying on different modeling approaches than those used in free turbulent flows. To this aim, a numerical database of highly-refined LES and CHT simulations is built and ...

Bound on vertical heat transport at large Prandtl number

We prove a new upper bound on the vertical heat transport in Rayleigh-Bénard convection of the form c Ra 1 3 (lnRa) 2 3 under the assumption that the ratio of Prandtl number over Rayleigh number satisfies Pr Ra ≥ c0 where the non-dimensional constant c0 depends on the aspect ratio of the domain only. This new rigorous bound agrees with the (optimal) Ra 1 3 bound (modulo logarithmic correction) ...

Fluid Flow and Heat Transfer of Nanofluids over a Flat Plate with Conjugate Heat Transfer

The falling and settling of solid particles in gases and liquids is a natural phenomenon happens in many industrial processes. This phenomenon has altered pure forced convection to a combination of heat conduction and heat convection in a flow over a plate. In this paper, the coupling of conduction (inside the plate) and forced convection of a non-homogeneous nanofluid flow (over a flat plate) ...
