Radiator Transient Heat Transfer in Room, ANSYS Fluent CFD Training

The problem is simulating heat transfer by a Radiator inside a room by ANSYS Fluent software. We perform this CFD project and investigate it by CFD analysis.

The radiator is attached to a sidewall, which is a heat source. The radiator consists of hot water flow pipes and aluminum fins. It is assumed that the hot water flow inside the pipes has a constant temperature. As a result, the body of the pipes has a constant temperature equal to 353 K.

The walls of the room have a thickness of 0.3 m, which has convection heat transfer with the outside; Thus, the ambient air temperature is assumed to be 284 K, and the convection heat transfer coefficient is considered to be 8 W/m2K.

Radiator in Room Methodology

The gravity effect is applied to the model. Also, The simulation is transient.

The present 3-D model is drawn utilizing the Design Modeler software. The current model consists of a room in the shape of a rectangular cube with dimensions of 4 m * 3 m * 3 m, and a radiator inside is connected to one of its sidewalls.

The model meshing has been done using ANSYS Meshing software, and the mesh type is unstructured. The element number is 4148881.

Radiator in Room Conclusion

The purpose of this study is to investigate the heat transfer rate from the radiator to the room’s interior using natural convection and the buoyancy effect. By analyzing the temperature contours, we can easily find the heat transfer in the room space by applying the radiator as a function of time.
