## Description

In this project, the conjugate heat transfer (CHT) of airflow in a simplified 4-story wind tower is investigated by ANSYS Fluent software. We perform this CFD project and investigate it by CFD analysis.

The project’s 2D geometry is designed in the Design Modeler, and the computational grid is generated using ANSYS Meshing software. The mesh type is structured, and the element number is 6375.

## Wind Tower Methodology

In this problem, conjugate heat transfer (a combination of convective and conductive heat transfer) is modeled inside a wind tower. The diagonal wall on the computational domain’s right side has a temperature of 305K with a heat generation rate of 1000W/m3.

The airflow enters through the inlet boundary on the top left side of the wind tower with a velocity of 12m/s and a temperature of 300K. The air enters each of the 4 levels of the building to ventilate and reduce the temperature.

Also, to simulate natural convection, gravity is enabled in the Y direction, and the Boussinesq model is used to calculate the air density changes due to temperature change (the initial density of air is set to 1.225Kg/m3, and its thermal expansion coefficient is set equal to 0.00331 1/K)

## Wind Tower Conclusion

At the end of the solution process, two-dimensional contours related to the velocity, pressure, temperature, streamlines, and velocity vectors inside the computational domain are obtained.

The temperature contour shows the temperature of the heated wall and how the temperature is changed inside the wind tower.

Furthermore, by viewing the contours related to velocity, streamlines, and velocity vectors, one can easily understand that the airflow enters the top levels with more momentum and velocity due to the less hydraulic resistance between the top and bottom levels.

Nevertheless, as seen in the velocity vector contour, the forced airflow entering the bottom levels will cause a rotating airflow inside such levels.

Finally, the air will rise to exit through the pressure outlet boundary on the top right side of the wind tower as it collides with the diagonal hot wall due to the natural convection phenomenon.

This tutorial seems like a comprehensive source for understanding CHT in wind towers. Could you clarify if the gravity settings specifically affect the convective heat transfer within the simulation?

• MR CFD Support

Absolutely, enabling gravity greatly influences the natural convection process within the wind tower. Since warm air rises and cool air sinks due to density differences, activating gravity and employing the Boussinesq approximation allows the simulation to model the density changes due to temperature variations accurately, which are pivotal for capturing the essence of natural convection in such scenarios.

I want to use this tutorial for designing a real wind tower with minor modifications. Does it cover guidelines for assessing the changes needed for real-life buildings, or is it just a theoretical demonstration of airflow in a simplified structure?

• MR CFD Support

The Wind Tower (2-D) CFD Simulation Tutorial is designed as a theoretical guide to demonstrate airflow within a simplified wind tower structure. It utilizes concepts that can be foundational for designing a real wind tower, but applying modifications for real-life structures will need additional considerations based on practical design parameters, environmental conditions, and specific building codes. However, the tutorial provides a strong CFD framework that can be a stepping stone for more complex, real-world applications.

23. Jan Dooley

Could you describe how the gravity and Boussinesq model were critical for the natural convection simulation in this wind tower?

• MR CFD Support

Certainly! In the simulation, gravity is a vital factor as it drives natural convection currents within the wind tower. The introduction of gravity in the Y-direction allows the modelling of buoyancy effects, where warmer and thus less dense air rises, while cooler and denser air descends. The Boussinesq approximation accounts for the density changes of the air as a function of temperature, allowing the simulation to capture density variations due to thermal expansion or contraction. These combined effects help accurately model the natural convection processes that are integral to the thermal regulation in the 4-story wind tower simulation.
