Description
Heat Exchanger with Twisted Barrier, ANSYS Fluent CFD Simulation Training
The present problem simulates heat transfer within a heat exchanger in three dimensions using ANSYS Fluent software. In this simulation, the HEX consists of two parts; the upper part is for the passage of the hot current, and the lower part is for the passage of the cold current. Also, a twisted barrier is used inside the HEX to affect the flow rate of hot and cold water and, consequently, increase the heat transfer between them. Hot water flow with a speed of 5 ms-1 and temperature of 340 K enters from the upper part of the HEX, and cold water flow enters with a speed of 5 ms-1 and temperature of 300 K from the lower part. This work investigates the heat transfer process between the cold and hot sides of the HEX.
Heat Exchanger Geometry & Mesh
The present model is designed in three dimensions using Design Modeler software. The present model is related to a heat exchanger, consisting of two parts (the hot part at the top and the cold part at the bottom), and a twisted barrier is used inside it.
We carry out the model’s meshing using ANSYS Meshing software. The mesh type is unstructured. The element number is 1201056. The following figure shows the mesh.

We consider several assumptions to simulate the present model:
- We perform a pressure-based solver.

Heat Exchanger with Twisted Barrier Results & Discussions
At the end of the solution process, two-dimensional and three-dimensional counters related to pressure, velocity, and temperature inside the heat exchanger are obtained. Two-dimensional and three-dimensional path lines and two-dimensional and three-dimensional velocity vectors are also obtained. The results show that heat transfer has occurred between the cold and hot sides of the heat exchanger.

I’m impressed with how this training demonstrates heat transfer within a complex geometry! Do the twisted barriers significantly increase overall heat transfer efficiency compared to straight barriers?
MR CFD Support –
Thank you for the positive feedback! Yes, the twisted barrier design significantly enhances the turbulence of the flow within the heat exchanger, which in turn increases the heat transfer rate and efficiency as compared to a heat exchanger with straight barriers.
Mrs. Maria Schmeler –
I’m impressed by the level of detail in the simulation method for the Heat Exchanger training. The twisted barrier seems to be a unique feature. How effective is it in enhancing the heat transfer as compared to traditional straight baffle designs in HEXs?
MR CFD Support –
The twisted-barrier design in this heat exchanger plays a significant role in enhancing heat transfer. It promotes turbulence and increases the overall heat exchange area, which improves the thermal efficiency compared to straight-baffle designs that offer less disturbance to the flow pattern. The increased heat transfer rate is crucial for the efficiency of the system.
