ShareSummary
The paper presents new wall functions of velocity and temperature for natural convection along vertical plates based on dimensional analysis and experimental data. Because only fluid properties and local parameters are included, the proposed wall functions are suitable for numerical simulation and are expected to be also valid in non-isothermal flows in cavities. Moreover, a certain analogy of length, velocity, and temperature scales between natural and forced convection has been found.
