In order to compare and research the performance of airflow level posture sensor two wire structure and three-wire structure. By using FLUENT-CFD software, through modeling, meshing, solving and other methods, Respectively, the airflow level posture sensor of two-wire structure and three-wire structure are simulated in the sensitive of the velocity field of different tilt angles and different heat source temperatures. The results showed that the tilt sensitivity to changes of velocity of three-wire structure airflow level posture sensor is 0.3831·10-3m/s/0, and the two-wire structure is 0.2487·10-3 m/s/0, and the measurement range of three-wire structure airflow level posture sensor is 00 to 300, the two-wire structure is 00 to 200. The rate of change of three-wire structure airflow level posture sensor’s sensitive internal velocity difference change with the hot source temperature is 1·10-5m/s/0C, and the two-wire is 3.5·10-5m/s/0C. The performance of three-wire structure airflow level posture sensor in inclination and temperature is better than the two-wire structure’s.

The Diffuser Augmented Wind Turbines (DAWTs) have been widely studied, since the diffusers improve the power coefficient of the wind turbine, particularly of small systems. The diffuser is a device which has the function of causing an increase on the flow velocity through the wind rotor plane due to pressure drop downstream, therefore resulting in an increase of the rotor power coefficient. This technology aids the turbine to exceed the Betz limit, which states that the maximum kinetic energy extracted from the flow is 59.26%. Thus, the present study proposes a mathematical model describing the behavior of the internal velocity for three conical diffusers, taking into account the characteristics of flow around them. The proposed model is based on the Biot-Savart's Law, in which the vortex filament induces a velocity field at an arbitrary point on the axis of symmetry of the diffusers. The results are compared with experimental data obtained for the three diffusers, and present good agreement.

AbstractBy observing the difference in optical depths between absorption spectra toward the two components of double sources we have measured the variations in opacity over lengths of less than 0.1 up to 10 pc inside diffuse interstellar clouds. Significant variations are detected on scales larger than about 0.2 pc, but not less. This may represent the minimum size for diffuse cloud structure. By comparing the variations of Gaussian fitted line parameters we find that variations in the internal velocity field of diffuse clouds explain the data rather better than tiny independent “cloudlets.”
