Description
Project Description
The present problem simulates heat transfer by a radiator inside a room. In fact, the heater is connected to one of the sidewalls of the room, which acts as a heat source, and its body has a constant thermal flux equal to 1886.792 W.m-2. The sidewalls and ceiling have a thickness of 0.2 m of wood, which has convection heat transfer with the outside; Thus, the ambient air temperature is assumed to be 280 K and the convection coefficient is assumed to be 10 W.m-2.K-1. The purpose of this study is to investigate the heat transfer rate from the heater to the interior of the room using natural convection and buoyancy effect. Therefore, the gravity force is applied to the model.
Room and Heater Geometry & Mesh
We carry out the present 3-D model using the Design Modeler software. The present model consists of a room in the shape of a rectangular cube with dimensions of 4 m * 3 m * 3 m and a heater in the shape of a rectangular cube with dimensions of 0.1 m * 0.8 m * 0.5 m in its interior which is connected to one of the room’s sidewalls. The figure below shows the geometry.
The meshing of room and the heater is done using ANSYS Meshing software and the mesh type is structured. The element number is 87865. The figure below shows the mesh.
Room HVAC by a Heater CFD Simulation
To simulate the present model, several assumptions are considered:
- We perform a pressure-based solver.
- The simulation is steady
- The gravity effect on the fluid is equal to -9.81 m.s-2 along the z-axis.
