摘要
Various helical coordinate systems used for mathematical description of the heat transfer and hydrodynamics problems of fluid flow in the channels with helical symmetry (invariance with respect to shifts along the helical lines) which are widely used as intensifiers of convective heat transfer are discussed in the article. Impossibility of constructing the orthogonal helical coordinate system is proved. The most simple and convenient type of helical coordinate system is obtained.
