| 内容記述 | A thermal analysis for transient response of ablating materials made of high molecular compounds is developed on the basis of the two-layer thermal model by use of an appropriate numerical method, where the assumptions of quasi-steady boundary layer flow and the equilibrium vaporization at the ablating surface are employed. Numerical computation is carried for an ablating blunt body of revolution made of Teflon with an emphasis laid on the effect of the second-order transition-i.e., the gel layer. It is shown that the transient internal temperature near the ablating surface is diminished considerably by the existence of the gel layer. Comparison of the numerical results with the experimental data reveals a remarkable fact that the single-layer thermal model does not predict the real feature of the transient thermal field, while the two-layer thermal model agrees well with the experiment, thus confirming the validity of the present approach. | |||||||
