In the present lecture some basic problems of state and solving of radiation heat transfer equation as applied to radiation modelling in shock-tubes and entry flow are discussed. The lecture contains five parts. In the first part the radiation heat transfer equation and the general definitions of the radiation heat transfer theory are presented. The definitions introduced in the first part are widely used in other parts. The second part of the lecture Chapter 3 presents four methods which are used for solution of radiation heat transfer problems in different aerospace applications. Well known problem of radiation heat transfer in heated gases and low-temperature plasma in view of atomic and molecular rotational lines, as well as of the vibrational molecular bands, are discussed in the third part. Some untraditional models of radiation heat transfer are presented in this part. The fourth part of the lecture is dedicated to the Monte-Carlo algorithms which are also in common use in aerospace problems, especially at prediction of emissivities of heated and radiating volumes of light-scattering gases. Several traditional and novel algorithms are presented in this part. The final part Chapter 6 of the lecture presents examples of using of numerical simulation methods described in previous parts at solution of various radiation heat transfer problems in aerospace applications. It should be stressed that the methods of the radiation heat transfer integration and various numerical simulation results presented in the lecture were used and obtained by the author at solution of concrete problems of aerospace physical gas dynamics.
