- Abstract
- One of the primary questions concerning the use of three-dimensional numberical methods to predict the complex fluid dynamic interaction between natural convection and radiation in enclosures or smoke dynamics in building is how the prediction can be verified. The validation of computational results requires a combined computational and experimental effort because the experimental configuration and boundary conditions must be sufficiently resolved and accurately modeled to obtain a meaningful comparison between the predicted and measured results. During this seminar, a research program aimed at providing detailed comparisons between measurements and predictions of three-dimensional natural convection flows in cubical enclosures with differentially heated walls will be discussed. Computational results obtained for Rayleigh numbers up to 10(8) and preliminary experimental results will be presented.
