![]() ![]() ![]() Its journey to higher parts of the room will again lose its temperature gradually and falls. The hot air will travel upward because of the decreased density. Now this heated air will move upward because of both forced and natural convection.Īs we previously discussed airflow movement due to the natural and forced convection, the flow pattern, and streamlines we can observe in streamline contour. We obtain and present Contours of pressure, velocity, temperature, etc.Īs shown in the pressure contour, the pressure near the heater has decreased because of the heated air and its movement. You should note that the ideal gas equation opts to capture the changes in the air density due to temperature change. ![]() To simulate this project we use the RNG k-epsilon model to solve turbulent flow equations and the Energy equation to calculate the temperature distribution inside the computational domain. We use the unstructured mesh type for this geometry and the element number is 207707. The air inside the room passes over a heater placed on one side of the room and a fan is responsible to push the heated air into the room.Īlso, we design the geometry of this project in Design Modeler and meshed it in ANSYS meshing. In this project, we study fan heater performance and the movement of the heated airflow inside a room by ANSYS Fluent software applying a steady state, and Pressure-based solver, considering the gravity effect.
