摘要：

The present work deals with free convection of polyatomic gas, for which the thermal conductivity, viscosity and specific heat are assumed to vary with absolute temperature according to a simple power law, the density is taken as inversely proportional to absolute temperature at constant pressure, while the Prandtl number is assumed constant. The energy equation is so revised as to consider the variation of the specific heat with temperature, and the governing partial equations for laminar free convection of the polyatomic gases are treated as dimensionless ordinary equations by similarity transformation. The numerical results are given and are well discussed.
