High aspect ratio convection near an inversion layer

Conference · · Trans. Am. Nucl. Soc.; (United States)
OSTI ID:7189720
Time-dependent nodal integral methods (TDNIMs) for natural convection were initially developed assuming a linear buoyancy term; they were applied to various bifurcation phenomena and to a brief study of dissipation effects. These methods have now been extended to the study of natural convection in a cavity near a fluid density maximum. Two versions of the TDNIM were developed, and regions of validity were determined. The low-order approach was used here to explore the solution types near a fluid density maximum in the Benard problem with ..beta.. > 1. Because the low-order approach was used, the restriction Ra << 10/sup 5/ applies for the coarse-mesh calculations employed in this study.
