The paper presents the results of systematic analysis of convective heat transfer and fric-
tion at the critical point of the sphere on the basis of the numerical solution of boundary
layer equations. It is found that the error in known formulae is significantly higher than
indicated in the literature. The system of relations characterized by an increased accura-
cy in the calculation of heat transfer and friction is offered.
Key words
: heat transfer, critical point, numerical methods, boundary layer
