Description
Description
This simulation is about a cylindrical heat source via ANSYS Fluent software. We perform this CFD project and investigate it by CFD analysis.
In this project, the steady heating process of airflow in a cylindrical geometry is investigated. Airflows in the hollow space between two concentric cylinders while a constant heat source of 252972 W/m3 heats the air.
A solid aluminum cylinder is used as a heat source. Air enters and exits the domain with a temperature equal to 300 K and 1758 K, respectively.
The geometry of the present model is drawn by Design Modeler software. The model is then meshed by ANSYS Meshing software. The model mesh is unstructured, and 1600000 cells have been created.
Cylindrical Heat Source Method
In this simulation, a Heat Source is defined in the cell zone condition to define the heat from the aluminum cylinder body. This heat source indicates that a certain heat value is produced volumetrically per unit of time and is continuously distributed in the computing zone.
Cylindrical Heat Source Conclusion
After simulation, the contours of temperature, velocity, and pressure are obtained. Airflow average velocity at the inlet and outlet is 0.00878484 m/s and 0.0353417 m/s, respectively.
This significant rise in velocity magnitude is due to the reduction of the cross-sectional zone of flow. Air temperature at the inlet and outlet is equal to 300 K and 1759 K, respectively, resulting in a heat transfer rate of 3.4 W/m2.
Also, the plot of the fluid temperature along the axial direction of the model has been obtained. The plot shows that the temperature of the fluid is increasing during the model. Also, the maximum temperature increase occurs in the model’s initial areas.

I’m intrigued by the simulation setup for the cylindrical heat source. Can you please explain a bit more about how the temperature of the air vastly increases as it moves through the model?
MR CFD Support –
As air moves through the space between the two concentric cylinders, it is subjected to the constant volumetric heat source from the solid aluminum cylinder. The heat source heats the air, gradually increasing its temperature. Additionally, due to heat transfer principles, when air passes through the heated section, it gains thermal energy which significantly enhances its thermal state, hence a stark temperature increase is observed. The continuity of heat source and the conductive properties of aluminum further promote this temperature rise along the axial direction.

I’m interested to know more about the type of mesh used. How was it determined to be the best choice for this simulation of a cylindrical heat source?
MR CFD Support –
In simulating the cylindrical heat source, an unstructured mesh was used due to its flexibility in handling complex geometries and boundaries. The decision to use this type of mesh is based on its ability to conform more easily to the cylindrical shape, providing a more accurate representation of the domain compared to a structured mesh. Additionally, an unstructured mesh allows for local refinements where high gradients of temperature or velocity are expected, thus improving the overall quality of the simulation results.

Could you please clarify if the difference in air temperature at the inlet and outlet results in any thermal expansion issues within the simulation?
MR CFD Support –
In the simulation of the cylindrical heat source, thermal expansion is accounted for. The increase in air temperature results in an expected decrease in density and corresponding increase in air velocities as per the contoured results. The simulation would include effects of temperature changes on material properties like density within the given boundary and initial conditions.

Blaze Walter –
The tutorial was handy for understanding how to set up the heat source and evaluate the temperature distribution. However, I’m curious, how is the boundary layer near the wall of the inner cylinder treated in the meshing process, particularly given the high-temperature gradients expected?
MR CFD Support –
In the meshing process, to capture the steep temperature gradients near the wall of the inner cylinder, inflation layers should be added in ANSYS Meshing software. These layers permit a finer mesh near the wall to improve the resolution of the boundary layer and allow for accurate prediction of the temperature distribution and thermal boundary layer. The thickness and number of inflation layers are usually decided according to the expected temperature gradients and flow characteristics.
