Visualization Visualization Visualization is a process where the CFD data is displayed in a way that lets you see what the field looks like. It does not lend itself to calculating heat transfer rates and other information, but does provide a very good interpretation of what is happening. The following figure shows the temperatures in a room that is heated by a radiant panel positioned on the ceiling. A large window is positioned in the middle of the back wall. The three separate cases show the effect of moving the heater further from the window.
Cold temperatures are blue and hot temperatures are red.
The top left graphic illustrates the temperature with the heater closest to the window. The top right graphic shows the room temperature when the heater is positioned a little further away from the window. The bottom graphic is the result when the heater is furthest away from the window. A quick glance immediately shows that the window temperature and the wall is much warmer when the heater is close to the window. The wall becomes progressively cooler as the heater is moved further from the wall.
