BY : CHAM Development Team - F Liu DATE :   1999
FOR : Demonstration Case
PHOENICS Version : HOTBOX VR
NOTES : Three-dimensional, steady flow, natural convection, conjugate heat transfer, Cartesian computational grid

Description of the problem:

Solution procedure:

Results:

All the pictures as shown below are created via the Virtual Reality Graphic Interface, a strong feature of HOTBOX-VR.

1. Velocity vectors
Velocity vector across the component in z direction
Velocity vector not across the component in z direction
Velocity vector across the component in x direction

From the figures above, the velocity predicted is symmetric along the x mid-plane, which is also evident from the temperature and pressure contours followed. The most of air flow is circling within and near this mid-plane.

2. Temperature contours
Temperature contour across the component in z direction
Temperature contour not across the component in z direction
Temperature contour across the component in x direction

It is clearly seen that the circling air is cooling the component and the temperature distribution around it is very much following the flow pattern.

3. Pressure contours
Pressure contour across the component in z direction
Pressure contour across the component in x direction

Conclusions:
