The main advantage (8.3) is the excluded transverse velocity, even now being the cause of the instability of the numerical solution.
For a plate (8.3) it will be quite simple.:
(8.4)
By specifying a polynomial for a velocity, the coefficients of which are found from the physical concept of boundary conditions:
( ), is located, but the friction stress and friction force are as ∫ |

Later, Professor Kruzhilin (MEI) analytically integrated ratio was obtained for the flow rate of the thermal boundary layer.
Calculations of the turbulent boundary layer can also be performed using the Pocket’s integral ratio, however, with its own law for friction stress, which is impossible without using experimental data. Known empirical methods for calculating Falkler and Droblenkov in the case of the plate.
