AIR JETS

7.4.1 Introduction

Air supplied into the room through the various types of outlets (grills, ceiling — mounted air diffusers, perforated panels, etc.) is distributed by turbulent air jets. In mixing-type air distribution systems, these air jets are the primary fac­tor affecting room air motion. Numerous theoretical and experimental studies that developed a solid base for turbulent air jets theory were conducted con­currently in different countries (Germany, Sweden, Russia, the UK, and the United States) from the 1930s through the 1980s. Theory of air jets and air distribution design principles are discussed in this section.
