modelWindowWithoutShade

Natural convection in an empty room with exterior walls, windows without shade

Extends from Modelica.Icons.Example (Icon for runnable examples), Buildings.ThermalZones.Detailed.Examples.FFD.BaseClasses.PartialRoom (Partial model for a room).

Information

This model tests the coupled simulation of Buildings.ThermalZones.Detailed.CFD with the FFD program by simulating natural convection in a room with only exterior walls and windows.

Figure (a) shows the schematic of FFD simulation. The walls are exposed to the ambient environment. Both the wall and window are well insulated and the initial temperature of the walls and the window is 20°C.

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