Shapemaker has been used here to create the spiral rib object and the case presented makes use of it for the situation when the ribbed tube is cooled down by natural convection in a cylindrical chamber.
This case deals with the free-convection flow of fluid arising in an annular cavity the inner rib augmented tube of which has higher temperature than the outer chamber surface.
The independent variables of the problem are the three components of cylindrical polar coordinate system, namely X, Y and Z.
The main dependent (solved for) variables are:
The Boussinesq approximation is used to incorporate the temperature dependence of the density.
The plots show the distribution of velocity and temperature within the enclosure.
Pictures are as follows :
All model settings have been made in VR-Editor of PHOENICS 3.6.2
