Crude Oil Cooling in a Finned Tube Heat Exchanger, CFD Simulation ANSYS Fluent Training
The present simulation is about the cooling of crude oil in a heat exchanger via ANSYS Fluent. In this project, a heat exchanger is designed with a central tube and several parallel plates.
The flow of crude oil enters the central pipe at a speed of 2 m.s-1 and a temperature of 200 C, and the flow of outside air moves at a speed of 0.3 m.s-1 and a temperature of 25 C towards the central pipe.
The temperature difference between the pipe and the external current leads to heat transfer, and the presence of parallel plates made of copper also contributes to the heat transfer process.
Geometry & Mesh
The present geometry is designed in a 3D model via Design Modeler. The computational zone is the interior space of a heat exchanger. In this heat exchanger, a central tube and several rows of parallel plates perpendicular to the pipe are designed.
The mesh of the present model has been done via ANSYS Meshing. Mesh is done unstructured, and the number of production cells is equal to 5945156.
Set-up & Solution
Assumptions used in this simulation :
- Pressure-based solver is used.
- The present simulation is steady.

Crude Oil Cooling in a Heat Exchanger Results
After calculation, 2D and 3D contours related to temperature, pressure, and velocity are obtained.
The contours show that heat transfer occurs between the crude oil flow inside the pipe and the outside airflow, causing the crude oil to cool inside the tube.
You can obtain Geometry & Mesh file and a comprehensive Training Movie that presents how to solve the problem and extract all desired results.
