In order to study the pressure fluctuation characteristics along the axis and cross-section of the flow over slender body in multi-vortices area at high angels of attack and zero slip,an experiment of pressure measurement has been carried out in subcritical Re number range.

The graphical method of wrap profile modification using twin-circular arcs for two,three and four wraps was established,and the general profile modification method using twin-circular arcs for multiply wraps with random wrap number was obtained.

In order to extend the type of meshing profile of multiply wraps,the regular polygon involute is proposed to form the profile of multiply wraps.

The characteristic of turbulent heat transfer and flow resistance with multi-longitudinal vortexes in tube is numerically analyzed.

Multi-Scroll Jerk Chaotic Attractors and Its EWB Implementation

A realization of multi-scroll chaos generation is presented using two CNN cells with hysteresis output function in the paper.

A simple formulas is presented for determining the turning point voltages, which give rise to multi-scroll chaotic attractors, of a piecewise linear A-V characteristic.
