Nonisentropic compressible flows are ubiquitous in many mechanical, chemical, and aerospace engineering applications, including gas turbines in their inlet systems, compressors, combustors, turbines, and exhaust systems. One-dimensional treatment of these flows forms the basis for most preliminary/conceptual designs. They are, however, generally counter-intuitive. For example, it defies common sense that the wall friction accelerates a subsonic compressible flow in a constant-area duct with or without heating. This workshop will provide a comprehensive review and reinforcement of the key concepts of one-dimensional compressible flows with simultaneous area change, friction, heat transfer, and rotation, which is seldom found in a textbook. In addition to the key concepts of thermofluids such as stream thrust, impulse pressure, rothalpy, mass flow functions, impulse functions, and normal shock function, this workshop will present an easy method to compute pressure and temperature changes in a generalized vortex in both rotor and stator reference frames. The workshop will conclude with a design-friendly overview of a compressible flow network featuring internal choking and normal shocks along with robust solution methods. A number of design-relevant examples will also be solved in the workshop. It behooves CFD engineers to use the unique foundation developed in this workshop as a prerequisite for all their 3-D CFD analyses, including physics-based interpretation of boundary conditions and computed results for design applications.
This workshop will be of interest to graduate students, research workers in universities and research institutes, and research and design engineers in industry who are involved in the physics-based thermofluids design and technology development of various components and systems, including high-performance gas turbine components such as inlet systems, compressors, combustors, turbines, diffusers, exhaust systems, internal air systems, and turbine airfoil internal and film cooling.
