![]() ![]() ![]() ![]() It has been found, however, that the solution methods reported in the literature may be inoperative for seals with small clearance-to-length ratio, or when the seal is appreciably distorted. This nonlinear equation has been solved numerically by various authors, for nozzle, diffuser, duct, seal, and similar applications. Isentropic flow through a passage of varying cross section.ĭetermination of leakage flow and separation force of gas turbine engine mainshaft seals and similar devices represents a unique application of the quasi-one-dimensional compressible flow equation (6), (10). Stagnation temperature, pressure and enthalpy. Sonic velocity, Mach number, Mach cone, Mach angle. Momentum and energy equations for one dimensional steady state compressible fluid flow. Fundamentals of jet propulsion with applications. Discusses applications in aircraft and rocket propulsion, space flights, and pumping of natural gas. The subject of compressible flow or gas dynamics deals with the thermo-fluid dynamic problems of gases and vapours It is now an important part of the undergraduate and postgraduate curricula.
