Measurement of confined heated circular jet

The experiment of heated circular jet simulates the flow field of fire in an enclosed compartment. The key parameters that were studied in the experiment were the velocity and temperature of the flow. For safety purpose, the heated jet uses a much lower temperature as compared to a real fire. Wire a...
