| Title: | Solution of Integral Equation applying Finite Difference Approach for Evaluating Visible Radiation Exchange including Multiple Inter-Reflection in Building Enclosures |
| Authors: | Chhavi |
| Issue Date: | 28-Dec-2012 |
| Abstract: | Visible radiation exchange including multiple inter – reflection in enclosures makes significant contribution toward overall radiant flux density e.g illuminance level, which is important in lighting design for energy conservation in buildings. The exchange of visible radiation between internal surfaces of room is represented by an integral equation of the Poission Volttera Fredholm type which may be integrated only for idealized geometries and typical radiation excitations. In this paper, finite difference approach has been applied to solve the integral equation for evaluating visible radiation exchange involving multiple inter – reflection in building enclosures. For this purpose a typical cubical enclosure ( room ) with a north facing window has been considered and using IDMP daylight data as input data finite difference approach has been applied for solution of integral equation. The result has been compared with enclosures of assumed geometry as equivalent bi-hemispheres as well as a single integrating sphere for the same surface area as that of actual room under consideration. |
