Experimental and Theoretical Study of Thermal Insulation by PMR in Flat Air Collectors

Abstract

This work provides insight into the natural convection flows that occur within a building's envelope as part of a process to regulate building energy consumption reduction and guarantee good winter insulation and comfort. We performed various experiments to investigate the glass wool's ability to insulate in our ouargla region, and we then used a simulation calculation with the fluent CFD code to validate the experimental model we had selected. The major findings demonstrate how well glass wool performs as a thermal insulator during natural convection when two layers of air gaps are used.
