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.
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.
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.
