Introduction

 A.V. Ivanov, Y.S. Kachanov, D.B. Koptsev, 2010

The problem of three-dimensional laminar boundary layer receptivity to external disturbances is a significant part of the turbulence origin [1, 2]. Experimental investigations of this problem have been limited and conducted comparatively recently. Their results bear primarily qualitative information and, as a rule, cannot be directly used for quantitative comparison with theoretical approaches and for testing the methods of calculation of the flow receptivity to external disturbances.

Color diagrams and figures should be used only when it helps improve understanding. Figures must be centered. Captions must be typeset in 10 point size and the first letter must be capitalized.

Rotating the frame of reference, it is easy to transform r and  to the wave vector components , in local coordinates (x*, z*) with the x* axis parallel to the velocity vector at the boundary layer edge. Then, it is possible to estimate the phase velocities of energy-carrying modes dominant in the packet along x* as well as the corresponding phase velocities along the direction of the wave vector K by the formulas

Equations must be centred and right numbered. An empty line must be inserted before and after the equation:

,(1)

where  = 2f is the circular frequency.

Let us estimate the angle of inclination ' of the wave vector to the x' axis and * to the x* axis as

If there are severaltables,they must be numbered, table captions must be compact and positioned above the table. There is a table example following below.
