    Birch, D. Mateescu, D. However a disadvantage of the above end plate is that its chord lengths are relatively too large compared with the chord length of the screw blade. Iyengar, V.

    The measured turbulent shear stresses are found to become smaller in magnitude gradually towards the stern and to fluctuate inside the boundary layer in contrast with the classical boundary layer theory [ 2 ] [ 3 ] [ 4 ] [ 5 ]. III, W. Abate, G. Numerical results of optimum screws are given, including a comparison between the application of different types of end plates.

The required strength of the propeller also puts constraints upon the distributions of chord length and maximum profile thickness. Silva, D. If the boundary layer flow was not so dominant, the field fluctuations from flow separation would not be in the high-frequency region as shown numerically by Zhu et al.

In theoretical fluid dynamics, he has contributed towards an analytical solution method for unsteady internal flow when the pressure as well as the velocity is unknown. Supersonic and hypersonic How models derive from these principles, too.

This is a preview of subscription content, log in to check access. Furthermore it consists of velocity induced by the free vortex sheets themselves and by the presence of screw blades and end plates. The flow separation phenomenon is firstly and mostly necessary to be accurately simulated.

Advanced Search To improve the performance of a highly swept supersonic wing, it is desirable to have an automated design method that also includes a higher fidelity to the flow physics.

The wing section shapes obtained in all the test cases included the features predicted by previous studies.

His research finds applications in remediation of contaminated sites as well as mining of minerals through heap leaching. Theoretical values of the natural frequencies of different modes show an asymptotic relationship with the length and a linear relationship with the diameter of the attached fiber.
