A study of flow interference and heat transfer between two-cylinders at different orientations

Journal of Ocean Engineering and Science, 2021
A numerical investigation is carried out for the different orientations of a circular cylinder where the upstream cylinder moves with varying angles α = 0˚, 30˚, 45˚, 60˚, 90˚ with respect to the downstream cylinder in a fixed position at a gap ratio (L ...

An improved method of Nusselt number calculation [PDF]

Geophysical Journal International, 1987
A novel method for calculating the Nusselt number, Nu, in a steady-state Rayleigh-Benard convection problem is presented, in which calculations are done for a square box with constant temperature, free-slip boundary conditions at the top and bottom, and a reflection symmetry along the side walls.
