and structural dynamics. During this effort, elastic blade motion and co-processing capabilities have been included in a recent version of the computational fluid dynamics code (CFD). The CFD code is loosely coupled to computational structural dynamics (CSD) code using new interface codes. The CFD/CSD coupled

Coupled CFD/Building Envelope Model for the Purdue Living Lab

by Donghun Kim, James Braun, Serkan Gugercin
"... Many advanced HVAC components, such as chilled beams, rely on vertical temperature gradients for effective operation. Moreover, accurate assessment of environmental-quality must be based on conditions in appropriate occupied zones and not on large-scale averages. Accordingly, it is appropriate to co ..."

to consider indoor environment models that accurately reflect such spatially varying features. In the present case we develop a procedure for coupling a building envelope model to a CFD-based model for the indoor air environment. The formulation retains spatially varying features such as water-vapor content
