Common Function

Based on field theory and air dynamics theory, two kinds of different curvature blade rotation of velocity and its distribution area were simulated, through the establishment of the three-dimensional flow model for the scenery tower fan blade generator and the adoption of RNGK-epsilon turbulence model. Then reach a conclusion from comparison: Smaller curvature leaf has a higher wind speed than the bigger one, which is easy to wind energy conversion under the common function of the force in the rotating area.

Mesh Method

Establish the full three-dimensional flow model of the torque converter, proper mesh the model, select the appropriate boundary conditions, and use the sliding mesh method to deal with the interactions of the impeller, turbine, and reactor in different rotation speeds. Analysis the flow rate, pressure, and the loss of full flow field passage of the torque converter, elaborate the formation mechanism of the flow field, agreement with the experimental date compare to the calculated data, more accurate than the traditional single passage model compare to the full passage model, provide the direction of design optimization of the torque converter.
