## Project Description

The problem simulates the airflow inside a room considering a heater and analyses the heat transfer inside the room using single-sided ventilation by ANSYS Fluent software. Inside the room, an aluminum radiator is used as a heat source with an output energy of 23469 W.m-3. Also, a window is placed on one of the lateral walls for the outlet airflow. The boundary condition of the pressure outlet with the pressure equal to the ambient pressure (atmospheric pressure) and the backflow air temperature equal to the room temperature is used. The purpose of this study is to investigate the airflow behavior in the room.

## Geometry & Mesh

The 3-D geometry of the present model is designed using Design Modeler software. The model consists of a room measuring 2.15 m ⨯ 2.16 m ⨯ 3.32 m, with a rectangular cube heater at the bottom of one of its sidewalls. The following figure shows the geometry.

The meshing of the present model has been done by ANSYS Meshing software. The mesh type is unstructured and the element number is 987087. The following figure shows a view of the mesh.

## Single-Sided Ventilation CFD Simulation

To simulate the present model, several assumptions are considered, which are:

• The Pressure-Based solver has been performed.
• Simulation has been performed in both fluid and heat transfer modes.
• The present model is steady-state.
• The effect of gravity is 9.81 m.s-2 on the fluid.

Here is the summary of the steps for defining a problem and its solution in the table:

 Models Viscous model k-epsilon k-epsilon model realizable near-wall treatment standard wall function Boundary conditions Outlet Pressure outlet gauge pressure 0 Pascal Walls Wall Wall motion stationary wall heat flux 0 W.m-2 Solution Methods (single-sided ventilation) Pressure-velocity coupling SIMPLE Spatial discretization pressure second-order momentum second-order upwind density second-order upwind turbulent kinetic energy second-order upwind turbulent dissipation rate first-order upwind energy second-order upwind Initialization (single-sided ventilation) Initialization method Standard gauge pressure 101325 pascal velocity (x,y,z) 0 m.s-1 temperature 300 K

## Single-Sided Result

At the end of the solution process, two-dimensional and three-dimensional contours of pressure, temperature, and velocity, as well as two-dimensional and three-dimensional velocity vectors, are obtained. The two-dimensional contours and vectors are drawn in two sections, XY and YZ so that the contours on the YZ page are drawn in three different sections.

## Reviews

1. Annabell Balistreri

Can this simulation be used to optimize the placement of the heater and the ventilation?

• MR CFD Support

Absolutely! The results from this simulation can provide valuable insights into the optimal placement of the heater and the ventilation to achieve the desired temperature distribution.

2. Gaylord Smitham

This product seems comprehensive, but I’m curious about how natural convection has been taken into account alongside the ventilation in this setup.

• MR CFD Support

In this simulation, natural convection is taken into account by including the effect of buoyancy due to temperature differences. The density of the air changes with temperature, causing airflow due to the gravity vector being activated in the simulation. Together with the forced convection from the single-sided ventilation, this gives a realistic portrayal of airflow inside the room.

3. Greyson Ryan

The heater inside the room has an output energy of 23469 W.m-3. Was this the optimal heating power for maintaining a comfortable room temperature during the simulation, or were various heating powers analyzed to determine this value?

• MR CFD Support

In the simulation, we have used the specified heating power of 23469 W.m-3 as the input for the heater. This value was pre-determined as part of the simulation setup and was not specifically optimized within this simulation study. If needed, additional simulations can be performed with different heating powers to analyze the impact on room temperature and optimize for thermal comfort.

12. Kailyn Johns

The heater output is pretty specific. Did using an aluminum radiator as the heat source affect the accuracy of the simulation? I am intrigued by the material choice.

• MR CFD Support

Thank you for the interesting question! Yes, the choice of the aluminum radiator as a heat source does affect the accuracy of the simulation. Aluminum, being a good conductor of heat, would ensure a more uniform heating profile compared to other possible materials. It probably was considered for its high thermal conductivity which would impact the simulation results by allowing for a more consistent distribution of heat within the room, leading to a more realistic simulation of thermal patterns and airflow behavior.

15. Maya Lesch DVM

The well-organized materials and the depth of the analysis exceeded my expectations! Yet, I just wondered about one aspect—how does including the heater and accounting for that energy source 23469 W.m-3 affect the overall temperature distribution in the room?

• MR CFD Support

Thank you for your kind words. The heater plays a significant role in the simulation. Including the heater with a given energy source of 23469 W.m-3 introduces a thermal plume into the room, which results in a non-uniform temperature distribution. Convection currents cause the air to rise above the heater and subsequently circulate throughout the room, altering the temperature distribution. The simulation results correctly capture the impact of the radiator on the air temperature, showcasing areas of higher temperature near the heater and cooler regions farther away.

16. Carson McGlynn

How are the results of the simulation visualized?

• MR CFD Support

The results are visualized using contour plots of temperature and velocity, as well as pathlines to show the flow pattern of the air.

17. Alexis Waters Jr.

The aluminum radiator in this simulation acts as a heat source. Can you describe how it affects the temperature distribution in the room?

• MR CFD Support

The aluminum radiator generates heat energy with an output of 23469 W.m-3 and acts as the main heat source in the room. As a result, it creates a thermal plume of rising hot air due to its higher temperature compared to the cold air within the room. This induces a convective flow that drives the air upwards and towards the outlet window, hence disturbing the temperature distribution throughout the space. The effect of the radiator introduces a temperature gradient, warmer near the heater and cooler away from it.
