Porous Introduction

In recent decades, many studies on fluid flow and heat transfer in porous media have been conducted by researchers. A porous medium is formed in such a way 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. (Nano fluid)

Nano Fluid Heat transfer Project description

In this project, Nano-fluid flow heat transfer in a heat exchanger containing porous medium is simulated and analyzed by ANSYS Fluent software. The energy model is activated. Spalart-Allmaras model is activated for solving turbulent flow.

Porous Heat Exchanger Geometry and mesh

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

CFD Simulation Settings

The assumptions considered in this project are:

  • Simulation is done using a pressure-based solver.
  • The present simulation is considered to be steady and does not change as a function time.
  • The effect of gravity has not been taken into account.

The applied settings are summarized in the following table.

At the end of the solution, we obtain the contours of pressure, velocity, temperature, streamlines, and velocity vectors.

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