Environmental problem, fossil fuel resources reduction, and having fresh air have been led to increase the application of sustainable system with a natural pattern cycle. In this design, active ventilation system in a particular panel as concept that is used in a bridge connecting two spaces. This method has been proposed using CFD simulation. These panels are heating by solar radiation and the active approach is water in a set of bubbles containing water with Titanium nitride (TiN) particles. This heat is directed through narrow tubes to a copper plate. The cooper layer on the back of the panel balances the heat that enters the passageway. Titanium nitride can help to increase heat when combine with water. The heat and humidity generated is directed to the top of the roof which contains the cylinder for growing the plants. The shape of the bubbles and modules have been taken from the virus on a microscopic scale. Nature has the best sustainable form and function in environment. SCIENTIFIC PROCESS OF PROJECT: In this report, we examined the simulation of a simple glass panel on a bridge in winter. In the initial case, the solar flux is considered from top and next to panel 18 degrees Celsius in winter. We need a comfort temperature about 23 degrees Celsius, so this panel raise the temperature with area of contact further by designing five bubbles in the centre of polygon. Then we entered the geometry into ANSYS Meshing software to produce grid. A grid is prepared with the organization for simulation. The simulation is performed by the steady method in the k-ε-Realizable model. The air density approximation is used by the incompressible ideal gas method. The boundary condition is the pressure inlet. The coupling equations of velocity and pressure are also solved using the coupled algorithm. Results 1: In bridge simulation, the pressure drop value is -0.00016 Pascals and the bridge temperature value is 287.71742 degrees Kelvin. In the next step, we entered TiN panel into ANSYS Meshing software to produce grid. A grid is prepared with the organization for simulation. Results 2: In the present simulation, the temperature of the bridge is 300.67593 degrees Kelvin, which is about 2.5 degrees better than the previous case. DESIGN PURPOSE: Green construction methods, when integrated with eco-friendly design and construction provide the most significant benefits to reduce carbon footprint and actually lend a helping hand to the environment. Benefits of TiN capsule panel: Reduces Wastage of Water and Energy; Conserves Natural Resources; Improves Air and Water Quality; Protects Biodiversity and Ecosystems; Reduces Costs and Increase Value; Improves Occupant Productivity; Improves the Quality of Life; Minimizes Strain on Local Infrastructure.
