Description
Heller Indirect Dry Cooling Tower Transient Simulation, ANSYS Fluent Training
In this project, the transient simulation of the Heller cooling tower is investigated by ANSYS Fluent software. Heller cooling tower is an indirect heat exchanging mechanism in which airflow over the water stream and heat exchange process density decreases, and an upward flow is generated. In the present work, an ideal gas model is used for air density modeling. The ideal gas density model is based on the relationship between density and local fluid temperature. Higher the temperature, the lower the density, and the higher the upward force on fluid volume due to buoyancy effects.
Heller Geometry and mesh
The fluid domain’s geometry is designed in Design Modeler, and the computational grid is generated using Ansys Meshing. The mesh type is unstructured, and the element number is 230000.

Jennie Bartoletti –
This course modelled some impressive computational fluid dynamics! How do time steps affect the accuracy and computational expense in a transient simulation like this one?
MR CFD Support –
Happy to hear you’re impressed! In transient simulations like that of the Heller cooling cooling tower, time step size is critical for both accuracy and computational cost. Smaller time steps can lead to more accurate results since they capture transient effects better, but they can vastly increase computational time. Larger time steps, on the other hand, reduce computation time but may miss quick-changing phenomena, leading to less accurate results. The adaptive time step method here attempts to balance accuracy with computational efficiency by adjusting the time step size based on the flow’s transient nature.

This simulation’s focus on buoyancy effects is impressive. The review would benefit from detailing how these buoyancy effects impact the overall efficiency of the cooling tower. Are there results available that show the relationship between the buoyancy-induced velocity and the cooling tower efficiency at different operation conditions?
MR CFD Support –
Thank you for the positive feedback and interesting inquiry! The results in this simulation demonstrate the buoyancy effects and the resultant airflow velocities inside the Heller cooling tower. While the presented data highlights the successful simulation of airflow dynamics, additional simulations would be required to explicitly correlate these velocities with cooling tower efficiency at various operational conditions. Such analyses could include evaluation of heat transfer rates, cooling capacity, and tower performance in different ambient conditions, which are beyond the scope of the summarized results provided.

Fanny DuBuque –
I tried to follow the steps outlined in the training for setting up my own simulation using a similar geometry. However, I’m not sure if I should always use an unstructured mesh like in the project, could you specify when it’s preferable to use unstructured over structured mesh?
MR CFD Support –
Whether to use an unstructured or structured mesh depends on the geometric complexity of the domain and the flow characteristics. Unstructured meshes are preferred in complex geometries or where local refinement is needed, as they are flexible in covering irregular shapes. Structured meshes are typically used for simpler, more regular geometries and can provide more accurate solutions with fewer cells. However, they are difficult to generate for complex shapes. For transient simulations of a Heller tower, an unstructured mesh might be preferred due to the potential complexity of the domain.

In this simulation, the wall thickness parameter directly impacts the process of heat transfer within the cooling tower. It represents the physical width of the tower’s walls where the heat generation rate has been defined. The provided heat generation rate and wall thickness value together govern how much heat is conducted and then released into the air, which influences the air’s temperature, density, and movement as per the simulation’s parameters.
