modelRoomOnlyConstructionBoundary

Test model for natural convection in an empty room with only construction boundary.

Extends from Modelica.Icons.Example, Buildings.ThermalZones.Detailed.Examples.FFD.BaseClasses.PartialRoom.

Information

This model tests the copuled simulation of Buildings.ThermalZones.Detailed.CFD with the FFD program by simulating the natural convection in an empty room with only construction boundaries.

Figure (a) shows the schematic of the FFD simulation. The room is 1 meter in length, width and height. The temperature of the east wall is set to 40°C and the rest walls are at 10°C. The initial value for the temperature of the room air is 30°C. Two sensors are placed in the room center at (0.5 m, 0.5 m, 0.5 m) that measure the temperature and the velocity.

Figure (b) shows the velocity vectors and temperature contours in degree Celsius on the X-Z plane at Y = 0.5 m as simulated by the FFD.
