Nano Fluid Heat Transfer in a Porous Heat Exchanger, ANSYS Fluent Tutorial

Description

In this project, Nanofluid flow heat transfer in a porous medium heat exchanger is simulated and analyzed by ANSYS Fluent software.

In recent decades, many studies on fluid flow and heat transfer in porous media have been conducted by researchers. A porous medium is formed so that its volume includes pores and apertures.

Porous media have wide applications in industry, such as crude oil production, optimal insulation of buildings and heat exchangers with recovery, etc. (Nanofluid)

Incoming flow has a velocity of 1.63 m/s. Porous has a temperature of 343 k, and tube has a temperature of 293 k.  The energy model is activated.

The geometry of this project is designed in ANSYS design modeler® and is meshed in ANSYS meshing®. The meshes used for this geometry are structured for the upstream and downstream parts of the domain and unstructured for the middle part of the geometry. The total number of mesh cells is 1901882.

Nano Fluid Methodology

We have used a nanofluid as an incoming fluid flow in this simulation. The energy equation is activated to compute temperature changes.

Nano Fluid Conclusion

At the end of the solution, we obtain the contours of pressure, velocity, temperature, streamlines, and velocity vectors. The contours show temperature changes well. Especially in the area where there is prosthesis and velocity vectors are oriented according to the cavities.
