Abstract

Convective heat transfer of a sphere at low values of the Reynolds number (Re ≤ 65) is analyzed. It is shown that, in the region investigated, the theoretical parameters considerably exceed those obtained experimentally, due to the physically unjustified overestimate of the contribution of forced convection to the total. It is concluded that, for this range, one must set up a separate criterion equation in the form, as a minimum, of a quadratic polynomial in the Reynolds number.
previous article The systematic error of energy pyrometers due to the effect on the result of a measurement of the distance between the pyrometer and the object
next article The choice of the optimum conditions for measuring the thermal properties of materials by the plane “instantaneous” heat source method
