Abstract:In order to solve the safety problem resulted from low-altitude flight turbulence caused by smoke emissions, the traditional method simulates the total height of smoke emissions to assess the impact on navigation, but it can only simulate flight safety under mild turbulence. Therefore, this paper simulates the rise of smoke lift for the degree of moderate turbulence. By simulating the law of rising smoke, the process of forming plumes in the initial stage of smoke rising is analyzed. Combined with the thermal action of the smoke flow, the intensity distribution of the smoke turbulence is expressed by the eddy-dissipation rate (EDR). The smoke lift national standard formula is improved based on energy conservation and eddy-dissipation rate. A new model combining smoke height, temperature and eddy-dissipation rate under a certain degree of turbulence is proposed. Based on the simulation example of Urumqi Airport runway, the error of the result does not exceed 10%, which verifies the effectiveness of the smoke lift model. © 2019 IEEE.
