Geometrical Wake of a Smooth Taper*
نویسنده
چکیده
A transverse geometrical wake generated by a beam passing through a smooth taper is considered. Comparison of the existing theories for the impedance of smooth structures is performed to show that they agree in the frequency range determined by the dimensions of the transition region. A simple approach is developed for the calculation of the kick factor, which reduces finding of the kick factor to the solution of simple electrostatic and magnetostatic problems. Using results for the real part of the impedance of the taper, it is shown that the existing theory allows to accurately estimate the kick factor for the NLC Final Focus collimator.

A semi-analytical model for velocity profile at wind turbine wake using blade element momentum
The shape of wake behind a wind turbine is normally assumed to have a hat shape for the models used in wind farm layout optimization purposes; however, it is know from experimental tests and numerical simulations that this is not a real assumption. In reality, the results of actual measurements and detailed numerical simulation show that the velocity in wake region has a S-shape profile. Th...

متن کاملThe Effect of Square Splittered and Unsplittered Rods in Flat Plate Heat Transfer Enhancement
A square splittered and unsplittered rod is placed in a turbulent boundary layer developed over a flat plate. The effect of the resulting disturbances on the local heat transfer coefficient is then studied. In both cases the square rod modifies the flow structure inside the boundary layer. As a result, a stagnation point, a jet and wake area are generated around the square rod, each making a co...
