Explore how three‑dimensional transonic compressors are modeled and solved using a new numerical approach.
This work presents a practical study of compressor and propeller blade flow, using simplified physics to focus on how rotation affects relative flow around blades. It ties together theory, grid generation, and computational results to show what drives performance in transonic regimes.
The book introduces the physical setup of rotors, stators, and blade cascades, and explains the assumptions that lead to a velocity potential formulation. It covers how a polytropic, nonviscous gas with essentially constant entropy is used to simplify the equations of motion, and it discusses how weak shocks are handled with artificial viscosity. The text also describes a transformation that maps blade surfaces to a plane to handle periodicity, and explains the grid design and 3D to 2D comparisons used to study the influence of rotation speed on the flow around blades.
- How the governing equations are reduced to a solvable potential equation for steady and rotating frames
- How grid generation and coordinate transforms enable periodic blade analysis
- The numerical scheme and typical run details, including iteration counts and grid sizes
- What the results reveal about 3D effects versus two-dimensional cascades and practical code usage
Ideal for readers of engineering CFD and turbomachinery, this edition combines method, implementation notes, and example outcomes to support practical understanding of transonic compressor behavior.
