3786 (RP-464) -- Numerical Calculation of Room Air Motion - Part 1: Math, Physics and CFD Modeling PDF

Documents research on computational fluid dynamics (CFD) associated with the room air motion problem class. States the mathematical, hence computational, requirement is attainment of accurate approximate solutions to the incompressible, three-dimensional Reynolds-averaged Navier-Stokes equations for thermal flow in room geometries. Part 1 addresses the math/physics issue of CFD modelling and documents available and newly established CFD theoretical foundations, Part 2 documents performance assessments for a newly derived CFD algorithm, with validations for benchmark problems with known comparative solutions pertinent to the room air motion problem class, Part 3 presents and documents detailed results of a CFD computational experiment for flowfield prediction in a three-dimensional room geometry for a range of simulated turbulence levels, with detailed comparisons with available full-scale laboratory experimental data.
