Heat Exchanger with Inner Fins, ANSYS Fluent CFD Simulation Training

The present problem is to simulate a heat exchanger using ANSYS Fluent software. In this simulation, airflow enters the device at a velocity of 22 m.s-1 and a temperature of 313 K and exits the exchanger at a pressure equal to atmospheric pressure. For the operating mechanism of the device, it is assumed that the upper and lower surfaces of the device have a thermal boundary condition of the constant temperature type equivalent to a temperature of 323 K. Also, a curved central wall in this device with several rows of blades and fins is designed to help better airflow and better heat transfer.

This work aims to investigate the effect of high-temperature walls on the airflow temperature through the heat exchanger’s interior.

Heat Exchanger Geometry & Mesh

The present model is designed in three dimensions using Design Modeler software. The model includes a heat exchanger with dimensions of 0.0018 m, 0.0082 m, and 0.0162 m; So that its inlet and outlet ducts are on both sides, and a curved inner wall with several rows of fins is located inside it, and its upper and lower walls are distinguished as surfaces with temperature condition.

We carry out the meshing of the model using ANSYS Meshing software, and the mesh type is unstructured. The element number is 2039783. The following figure shows the mesh.

Heat Exchanger CFD Simulation

We consider several assumptions to simulate the present model:

• We perform a pressure-based solver.
• The simulation is steady.
• The gravity effect on the fluid is ignored.

The following table represents a summary of the defining steps of the problem and its solution:

Results

At the end of the solving process, three-dimensional and two-dimensional contours related to pressure, velocity and temperature are obtained. The contours show that the incoming air flow to the heat exchanger is affected by the hot walls and its temperature increases.

You can obtain Geometry & Mesh file and a comprehensive Training Movie that presents how to solve the problem and extract all desired results.

4. Zelda Balistreri

After completing this simulation, how should I adjust the cold-side inlet velocities to achieve a more efficient heat transfer without changing other parameters?

• MR CFD Support

To fine-tune the heat transfer efficiency, considering all other parameters remain constant, you can incrementally increase or decrease the cold-side inlet velocity and observe the effects on the temperature contours. By monitoring these results, you can determine the optimum velocity for maximum efficiency in your heat exchanger simulation.

5. Arvel Armstrong

What kind of meshing strategy was employed for the heat exchanger geometry?

• MR CFD Support

A structured meshing strategy was employed for the heat exchanger geometry. This strategy provides a high-quality mesh that is efficient for CFD simulations.

6. Dr. Maybelle Wisoky II

The provided training was extremely enlightening. It helped me grasp the fundamentals of setting up a heat exchanger model in Fluent with an impressive level of precision. The meshing details were particularly useful to ensure quality results. Is there any information available on how to evaluate the efficiency of the heat exchanger using the simulation results obtained from Fluent?

• MR CFD Support

I’m glad to hear the information was helpful. Evaluating efficiency typically involves comparing the temperature increase of the airflow to the theoretical maximum temperature change, given the temperatures and the properties of the airflow. This can be done post-processing within Fluent or by using the data exported from Fluent and calculating in a programming or spreadsheet environment. For heat exchanger efficiency, you’d look at the effectiveness, which is a measure of how close the heat transfer approaches the maximal possible for a given set up.
