Numerical Investigation and Performance Enhancement of Scramjet Inlets and Combustors - Softcover

Inhaltsangabe

Scramjet propulsion relies on the efficient compression, mixing, and combustion of air flowing through an engine at very high speeds. The inlet and combustor are therefore critical components in determining the overall aerodynamic and combustion behavior of a scramjet system. Numerical Investigation and Performance Enhancement of Scramjet Inlets and Combustors provides a focused introduction to the computational analysis, aerodynamic behavior, combustion processes, and performance-enhancement concepts associated with scramjet propulsion.

The book introduces the fundamental principles of air-breathing hypersonic propulsion and establishes the role of the scramjet inlet in decelerating and compressing incoming high-speed airflow while maintaining conditions suitable for supersonic combustion. Readers are introduced to concepts including compressible flow, Mach number, shock waves, boundary layers, pressure distribution, flow separation, and inlet performance. These foundations provide the necessary context for understanding the complex flow structures that develop within high-speed propulsion systems.

A central focus is placed on numerical investigation of scramjet inlet and combustor performance. The text discusses computational approaches for analyzing high-speed compressible flow, including numerical modeling, computational fluid dynamics, flow-field prediction, pressure and temperature distributions, and performance assessment. The relationship between computational parameters, geometry, boundary conditions, and predicted aerodynamic behavior is considered within a general engineering framework.

The book further examines scramjet inlet performance and methods for improving airflow characteristics. Topics such as shock-wave interactions, inlet compression, total pressure recovery, flow distortion, boundary-layer behavior, separation control, and mass-flow characteristics are considered in relation to inlet design. These concepts help readers understand the engineering trade-offs involved in developing inlet configurations capable of providing suitable flow conditions to the downstream combustor.Numerical Investigation and Performance Enhancement of Scramjet Inlets and Combustors explores computational methods for analyzing and improving scramjet propulsion components.
