Abstract: This research presents the history of research on the dynamic compatibility conditions on the oblique shock wave that define correlation of values of gas-dynamic variables before discontinuity and immediately after it. All relations can be used in numerical methods and applied for both compression shock waves and isentropic waves. The notion of shock waves polar is introduced. A research on their properties is conducted. Particular attention is paid to special points on shock wave polars and their significance for the research of shock wave properties and interference. Using step-by-step research works as an example, the researchers show the history of solving issues on interference of oblique shock wave between each other and other types of gas-dynamic discontinuities. A graphic method for solving problems of gas-dynamic discontinuity interference by using shock wave polars is provided.
