Title:
THREE-DIMENSIONAL CONTRACTED AIRFLOW NOZZLE AND METHODS FOR USE THEREOF
Document Type and Number:
Japanese Patent JP2018065550
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide apparatus and methods for providing a desired volumetrically conditioned airflow rate and for reducing a noise level, airflow recirculation and airflow separation.SOLUTION: An example apparatus includes a nozzle housing having a pair of opposing sidewalls 110 and a front wall 115 and a back wall 120 that define an airflow passage 125. The passage has a centerline 130 extending between an inlet 106 and an outlet 108 and has a plurality of cross-sections taken perpendicularly to the centerline that collectively define a smooth contour along a length of the passage. The cross-sections each have a thickness between the front and back walls that is greater at side edges than at the centerline. The thickness of the cross-sections decreases along a length of at least a first portion of the nozzle housing. A width of each of the cross-sections between the sidewalls increases along the length of at least the first portion of the nozzle housing.SELECTED DRAWING: Figure 2
