Study of the applicability of jet theory for large space air conditioning

Taking round nozzle as example, compares the results obtained by semiempirical formulas and those by CFD method. The research results indicate that the axes bend and the velocity decrease of the jet obtained by CFD method are more quick for parallel horizontal jet with multiple nozzles, and that the space size, interior thermal conditions and nozzle layout have obvious effect on jet distance, and that the interior temperature distribution is affected by the jet distance and the whole air distribution.
