Energy Transport Using Natural Convection Boundary Layers

    Research output: NRELTechnical Report


    Natural convection is one of the major modes of energy transport in passive solar buildings. There are two primary mechanisms for natural convection heat transport through an aperture between building zones: 1. bulk density differences created by temperature differences between zones and, 2. thermosyphon pumping created by natural convection boundary layers. The primary objective of the presentstudy is to compare the characteristics of bulk density driven and boundary layer driven flow, and discuss some of the advantages associated with the use of natural convection boundary layers to transport energy in solar building applications.
