Calculations showed that with an increase in Reynolds number, the maximum lift coefficient increases and minimum drag coefficient decreases. The paper also highlights the sectional Cp plots and pressure contours along with the velocity streamlines at different span-wise stations of an aircraft wing. ...
Significance tests of differences in the two periods were based on the coefficient of the interaction terms25. Sensitivity analyses Sensitivity analyses were performed on the parameters included in the models to test the robustness of our results. We extended the temperature lag to 27 days. We ...

This is achieved by programming a voltage at the CTRL pin with a negative temperature coefficient using a resistor divider with temperature dependent resistance (Figure 7). As ambient temperature increases, the CTRL voltage will fall below the internal 1V voltage reference, causing LED currents to ...

The lift forces generate a turning moment which forces the board to be turned in direction to the shore favoring the controllability and stability of the surfboard. The higher the angle of attack, the higher is the drag coefficient. Lift-to-drag ratio values showed that for speeding up small...
The response regime is associated with the energy transferred and the vortex shedding mode as well as the added mass coefficient and the phase lag between the cross-flow displacement and the lift coefficient. In the VIV branch, more energy is extracted from the ambient flow by the trapezoidal ...
In particular, the drag force coefficient is increased for all bridge-deck sections when the wind barrier is in place. This feature is particularly exhibited for the streamlined bridge-deck section. The wind barrier alters the trends and values of the lift force coefficient, while the influence ...
However, provided performance characteristics are only subjective and of descriptive nature. Therefore, we apply and analyze objective performance indicators as (1) lift and drag coefficient for each fin and the entire configuration and (2) lift-to-drag ratio for the entire fin configuration....
