Greenhouse Air Ventilation Ansys Fluent CFD Simulation Training

In this project, Greenhouse Air Ventilation CFD Simulation have been investigated using ANSYS Fluent software. We perform this CFD project and investigate it by CFD analysis.

The three-dimensional geometry of this project has been produced with SpaceClaim software. The length of the computational domain is 10 m, the height is 3.15 m, and the width is 4 m.

The meshing of this project has been done with ANSYS Meshing software. The element number is 216456.

Also, due to the nature of the present problem, the transient solver has been enabled.

Greenhouse Methodology

This project has been done using CFD numerical simulation method with the help of Ansys Fluent software. The air Ventilation is simulated in a greenhouse with two small fans with a radius of 5 cm that rotates at a speed of 100 rad/s.

The heat flux of 250 w/m^2 defines the lower wall of the greenhouse, and the sidewalls are defined by a coefficient of 30 and a free stream temperature of 300 K due to the thermal interaction with the outside air convection.

In this simulation, the radiation model is also activated to calculate the effects of radiation on heat and temperature transfer.

Moreover, the realizable k-epsilon model and energy equation are enabled to solve the turbulent fluid equations and calculate temperature distribution within the domain.

Also, it is set for the air density to obey the ideal gas law to change its density due to the temperature change.

Greenhouse Conclusion

At the end of the simulation, we can observe the air velocity and temperature counters. Over time, the air temperature near the greenhouse floor increases, and the density decreases due to the heat transfer from the floor, and the surrounding air has a higher density.

They replace the low air and cause heat circulation, and of course, the two existing fans also accelerate the circulation, and this cycle is repeated as well.

    I’ve heard the realizable k-epsilon model is quite effective. How did this specific turbulence model enhance the simulation for greenhouse air ventilation?

    • Avatar Of Mr Cfd Support

      MR CFD Support

      The realizable k-epsilon model is known for its accuracy in predicting the spread of turbulent jets, which made it suitable for simulating the complex air flow patterns in the greenhouse. It helped to accurately calculate the mixing of warmer air rising from the heat source with cooler air, resulting in a more realistic representation of temperature distribution and air circulation in the greenhouse environment.

    How does the inclusion of the realizable k-epsilon model improve the simulation?

    • Avatar Of Mr Cfd Support

      MR CFD Support

      The realizable k-epsilon model provides a means to more accurately simulate turbulent airflow within the greenhouse, which in turn, allows for predicting temperature distribution and airflow patterns with better precision. It accounts for the effects of turbulence intensity and length scales which are crucial in correctly determining ventilation efficiency and distribution of heat within the greenhouse.

    This tutorial was invaluable for my understanding of climate control in agriculture settings. Does the program in this CFD course provide solutions for anomaly detection, say if a fan were to fail or airflow was blocked?

    • Avatar Of Mr Cfd Support

      MR CFD Support

      Thank you for your complimenting our Greenhouse Air Ventilation CFD Simulation Tutorial. While the course focuses primarily on teaching airflow and temperature distribution simulations under normal operational conditions, it doesn’t specifically address anomaly detection scenarios such as fan failure or blocked airflow. Those types of scenarios would involve setting up additional simulation parameters and possibly incorporating more advanced diagnostic tools or techniques.

    I’m thoroughly impressed with the detail provided in this tutorial. The airflow is clearly visualized, leveraging the animation feature, and the temperature changes within the greenhouse are well-replicated. I found the incorporation of the rotation of the fans and the heat flux conditions to be particularly well-done. Between the visual content and in-depth analysis, this tutorial vastly increased my understanding of greenhouse air ventilation.

    I’m looking to simulate something similar in my research. Can this software handle multiple radiation sources, and was it part of this analysis?

    • Avatar Of Mr Cfd Support

      MR CFD Support

      Yes, ANSYS Fluent software can simulate multiple radiation sources. Although the description for the Greenhouse Air Ventilation simulation mentions only the heat flux from the lower wall, the radiation model activated in the simulation can, in fact, calculate the effects from multiple radiation sources. This feature allows for a comprehensive analysis of heat and temperature distribution within the simulated domain.
