    Philip Morris USA, Research Center, Richmond, VA, USA
    The relative positions of the thermal convection column and the smoke plume from a variety of smoldering cigarettes were measured using a combination of schlieren and visual optical systems. The schlieren technique is an optical method used to...

    Dynamic mass measurements of cigarettes by neutron radioscopy

    JENKINS R.W.; LANZILLOTTI H.V.; McRAE D.D.; BRENIZER J.S.; MORA G.A.
    Philip Morris USA, Richmond, VA, USA
    Neutron radioscopy is a technique that uses a beam of neutrons and a video-based neutron imaging system to produce real-time images of an object. The images, or more correctly, the two-dimensional projections of the object, look like X-ray images and...

    Assembly and calibration of an infrared thermal imaging system for the study of temperature distributions in cigarette coals

    MCRAE D.D.; JENKINS JR R.W.; BRENIZER J.S.
    Philip Morris USA, Richmond, VA, USA
    There are a number of thermal imaging systems available commercially that will convert the image of a scene or object as it appears in the infrared to a video signal that can be viewed on a television monitor. Since the infrared radiation emitted by...
