The aim is to understand how a wall-mounted radiator affects room temperature distribution, air circulation patterns, and overall heating efficiency in a typical indoor space. Project Objectives: Understand the principles of heat transfer and air circulation from wall radiator heaters. Analyze temperature distribution and airflow patterns in a room heated by a wall radiator. Evaluate the heating effectiveness of wall radiator placement. Assess the impact of radiator positioning on room comfort and temperature uniformity. Project Outline: Model a typical room with a wall-mounted radiator heater. Include relevant room features such as windows, doors, and furniture. Define boundary conditions to represent realistic scenarios: External ambient temperature Radiator surface temperature or heat flux Heat loss through walls, windows, and other surfaces Set up material properties for air, building components, and the radiator. Configure and run the CFD simulation in ANSYS Fluent: Use appropriate models for turbulence, heat transfer, and buoyancy-driven flows Consider both steady-state and transient simulations to capture heating dynamics Analyze simulation results, focusing on: Temperature distribution throughout the room Airflow patterns and velocities Heat transfer rates from the radiator to the room Thermal stratification effects Evaluate the heating performance of the wall radiator: Analyze time taken to reach desired room temperature Assess uniformity of heating across the space Investigate thermal comfort levels using appropriate indices (e.g., PMV, PPD). Visualize the results using ANSYS post-processing tools to create informative graphics and animations of temperature and airflow patterns. Consider the implications of the findings for room heating design and radiator placement. Discuss potential limitations of the simulation and areas for future investigation.
