Nusselt Number Correlation for Vertical Tubes with Inverted Triangular Fins under Natural Convection
Energies, 2017 Vertical tubes with inverted triangular fins under natural convection are investigated experimentally. The thermal resistances of tubes with inverted triangular fins are measured for various fin numbers, fin heights, and heat inputs.

Melting dynamics of large ice balls in a turbulent swirling flow
, 2013 We study the melting dynamics of large ice balls in a turbulent von Karman flow at very high Reynolds number. Using an optical shadowgraphy setup, we record the time evolution of particle sizes.

Large-Biot-number non-isothermal flow of a thin film on a stationary or rotating cylinder [PDF]
, 2009 Using the lubrication approximation we investigate two-dimensional steady flow of a thin film of fluid with temperature-dependent viscosity on a uniformly heated or cooled horizontal cylinder, which may be stationary or rotating about its axis, in the ...

Non-Oberbeck-Boussinesq effects in two-dimensional Rayleigh-Benard convection in glycerol [PDF]
, 2007 We numerically analyze Non-Oberbeck-Boussinesq (NOB) effects in two-dimensional Rayleigh-Benard flow in glycerol, which shows a dramatic change in the viscosity with temperature.

Use of Fin Equation to Calculate Nusselt Numbers for Rotating Discs [PDF]
Volume 5C: Heat Transfer, 2015 Conduction in thin discs can be modelled using the fin equation, and there are analytical solutions of this equation for a circular disc with a constant heat-transfer coefficient. However, convection (particularly free convection) in rotating-disc systems is a conjugate problem: the heat transfer in the fluid and the solid are coupled, and the relative

Numerical investigation of nanofluid flow and heat transfer over a backward-facing step
Engineering and Applied Science Research, 2020 In this research, the forced convection heat transfer of a nanofluid in a channel with a backward- facing step is studied by adopting the finite volume technique. The effect of nanoparticles is considered by employing the single-phase model.

Transition of thermally induced flow in a square cavity using Spectral Method [PDF]
E3S Web of ConferencesThis study presents a novel mesh-free method for simulating natural convection in a square cavity filled with Newtonian fluid. The proposed algorithm integrates mesh-free Spectral methods with the Moving Collocation Element (MCOE) technique and employs a

Upper bounds on Nusselt number at finite Prandtl number
Journal of Differential Equations, 2016 We study Rayleigh Bénard convection based on the Boussinesq approximation. We are interested in upper bounds on the Nusselt number $\mathrm{Nu}$, the upwards heat transport, in terms of the Rayleigh number $\mathrm{Ra}$, that characterizes the relative strength of the driving mechanism and the Prandtl number $\mathrm{Pr}$, that characterizes the ...
