Examination of three dimensional free convection analysis by experimental results of wall frictionlines visualizations
Abstract
The steady laminar free convection on the surface of a body having a three-dimensional configuration and heated to a uniform temperature is analyzed. The three-dimensional boundary layer equations for laminar free convection were used to predict the velocity and temperature distribution on the surface; the solutions are expressed in terms of an expansion series in two variables of coordinates along the wall surface. The wall frictionlines, lines showing the direction of wall frictional stress at the wall and representing the characteristics of the flow, are calculated using a few terms of the series for the case of an inclined circular cylinder. The results show good agreement with wall frictionlines obtained experimentally from an electrochemical technique.
