THERMALLY STRATIFIED WIND TUNNEL FACILITY

摘要

PROBLEM TO BE SOLVED: To provide a thermally stratified wind tunnel facility made capable of setting the air temperature distribution and flow speed distribution in a measurement region of the air duct in a necessary distribution at the wind tunnel experiment, by evading the generation of an excessive speed of air flow in the lower part of the air duct.;SOLUTION: The wind tunnel is characteristically constituted such that the blower generates air flow in the duct. At the upstream of the smoke sources provided in the air duct, a plurality of heaters are arranged in a vertical direction for heating the air and adjusting the temperature of the air in the air duct, thereby adjusting the temperature and wind speed of the air in the measurement region down stream of the smoke sources. Herein, at the upstream of the heater array, a set of separators of a plurality of air ducts separating in the vertical direction which straighten the air flow by the separator vanes for sending the air flow into the heater array.;COPYRIGHT: (C)2006,JPO&NCIPI
