ABSTRACT:
A fixed blade air mixing apparatus is characterized in particular by having a plurality of radially extending vanes which extend away from a common center and terminate at their outer ends in a generally polygonal shaped enclosure. The apparatus is principally intended for use in eliminating stratification of airstreams of different temperature flowing through a common passage, for example, in a heating, air conditioning or other ventilating duct, and the vanes are so constructed and arranged as to establish a predetermined discharge angle of the airstreams passing therethrough which when combined with a predetermined lateral clearance between the vanes will establish optimum mixing effectiveness and uniform velocity profile of the air downstream of the mixing apparatus with a minimum pressure drop as the air flows through the apparatus.
