UDC 536.25

Self-similar problems of free-convective heat transfer 
on a vertical flat semiinfinite plate for high Prandtl numbers and 
three types of thermal boundary conditions (an adiabatic surface, 
a constant temperature, and a constant heat flux on the surface) are 
solved by the method of internal and external expansions on the basis 
of the equations of a laminar boundary layer in the Boussinesq approximation. 
Asymptotic relations are found for the main characteristics. The results 
obtained are compared with the data of other authors.
