A numerical study of slow nonisothermal flows past axisymmetrical bodies
Abstract
It has been shown in an earlier work (Galkin et al., 1970) that slow gas flows past substantially heated or cooled bodies cannot be described by NavierStokes equations since thermal stresses must be allowed for in the momentum equation. These stresses give rise to several new effects, the most important of these being thermalstress convection, i.e., the motion of gas around isothermal bodies under the effect of thermal stresses. Here, thermalstress convection in the vicinity of homogeneously heated nonsymmetric bodies is investigated numerically for the case when the difference between the temperature of the wall and that of the unperturbed gas is small. It is shown that the integral force F in this case is close to zero.
