영문 초록

This paper is studied to investigate the effect of-slits and swirl vanes on the main flow fields of a gun -type gas burner through X-Y plane and Y-Z plane respectively by using X -probe from hot -wire anemometer system. This experiment was carried out with flow rate" 50 e /min in respective burner models installed in the test section of a subsonic wind tunnel. The burner models with only slits and only swirl vanes respectively were made by modifying original gun-type gas burner. The fast jet flow spurted from slits played a role such as an air-curtain because it encircled rotational flow by swirl vanes and drives mixed main flow to axial direction. As a result. the gun -type gas burner had a wider flow range up to about Y/R= 1.5 deviated from slits and maintains a comparatively large velocity in the central part of burner within the range of about X/R=2.5. Therefore, it was very desirable that swirl vanes were installed within slits in gun-type gas burner in order to control the main flow fields effectively.
