Description and analysis of plane waves in a temperature-inhomogeneous region
Original language description
Both from a scientific and practical point of view behavior of acoustic waves within a temperature-inhomogeneous region represents an interesting issue. However, there is a limited class of temper-ature functions for which we know exact analytical solutions of corresponding model equations. Our work extends this class by a temperature function with an arbitrary temperature gradient, and unlike previously published works, the temperature function is smoothly connected with a temperature of surrounding temperature-homogeneous regions. For the chosen temperature function the model equation represents Heun?s equation that can be solved exactly using the Heun functions, which facilitates study of the behavior of acoustic waves. The only software package currently able to work with the Heun functions is MAPLE. Alternative ways for evaluations of those functions do not exist. However, the calculation of the Heun functions in MAPLE has some limitations that can be overcome with the help of F-h
