Abstract
A SMOKE GENERATOR INCORPORATING THE TECHNIQUES OF LIQUID VAPORIZATION, CRYOGENIC COOLING, AND MICROPROCESSOR CONTROL WILL BE DEVELOPED. THE SMOKE GENERATOR WILL BE OPERABLE UNDER BOTH ATMOSPHERIC AND ELEVATED PRESSURES. LIQUID VAPORIZATION WILL BE ACHIEVED BY CONTROLLED FILM-BOILING. PRESSURIZED NITROGEN GAS WILL BE USED TO OPERTE A LIQUID NITROGEN ATOMIZER TO PRODUCE NITROGEN MIST REQUIRED FOR COOLING THE VAPOR AND THE PRODUCTION OF SMOKE. WIND TUNNEL EXPERIMENTS WILL BE PERFORMED TO DETERMINE THE PERFORMANCE OF THE SMOKE GENERATOR. THE VISIBILITY OF THE SMOKE GENERATED WILL BE MEASURED PHOTOGRAPHICALLY. THE EFFECTS OF DIFFERENT SMOKE PRODUCING LIQUIDS, THE EFFECTS OF DIFFERENT VAPOR MIXING RATIOS, AND THE EFFECTS OF DIFFERENT SMOKE INJECTION SPEEDS ON THE VISIBILITY AND THE PERSISTANCE OF THE SMOKE WILL ALL BE EXPLORED. THE SMOKE GENERATOR WILL BE INTEGRATED WITH A MICROPROCESSOR CONTROLLER FOR THE PURPOSE OF AUTOMATIC CONTROL. THE SPEED OF THE SMOKE AND THE SPEED OF THE FLOW OF INTEREST WILL BE SIMULTANEOUSLY MONITORED. THE MICROPROCESSOR CONTROLLER WILL ALSO BE USED TO CONTROL THE SMOKE INJECTION SPEED AND TO SEQUENCE THE FUNCTIONING OF THE SMOKE GENERATOR.
