  • Description of the surface geometry of the air shape in Maple

    The paper presents an analytical description of the unfolding surface of one of the products of light industry – aerodynamic shape. All surface elements are designed in the Maple environment based on the 4GL package commands. A set of commands allowing to describe surfaces and spatial curves analytically is proposed for the construction of 3D graphical objects. Elements sweep aerodynamic shape are conical and cylindrical sweep with a special character of their boundaries. The proposed description of the surface of the air shape allows you to design a technical product of specified geometric dimensions according to the calculated geometry of the elements of the air shape.

  • A description of the potential function for the more accurate equation of lines motion

    In the present work proposes a specified description of potential functions when the free spreading  in the two-dimensional turbulent flow of planning. In contrast to previous decisions, new parameter satisfies the continuity of flow when the flow flowing  from rectangular tubes on the discharging  track  

    Keywords: final line of motion, lines of equal potential, horizontal rectangular tube, diverting from the mainstream flow
