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.

Heat Transfer under Double Turbulent Pulsating Jets Impinging on a Flat Surface [PDF]
Journal of Heat and Mass Transfer Research, 2017 In this study, the numerical analysis of turbulent flow and heat transfer of double pulsating impinging jets on a flat surface has been investigated. The unsteady two-dimensional numerical solution for two similar and dissimilar jets was performed using ...
