Turbomachines: A Guide to Design, Selection and Theory by O. E. Baljé is a foundational 1981 text focusing on using dimensionless parameters to bridge theoretical fluid dynamics with practical design and performance prediction. It covers essential topics like Euler’s turbomachine equation and machine selection methodologies for compressors, turbines, and pumps. A version of this technical guide can be found on SciSpace.

O.E. Baljé’s Turbomachines: A Guide to Design, Selection and Theory (1981) provides a foundational approach to machinery selection using Specific Speed ( Nscap N sub s ) and Specific Diameter ( Dscap D sub s Turbomachines: A Guide to Design, Selection and Theory by O
Key geometric decisions:
Designing a turbomachine is a highly iterative process that transitions from abstract thermodynamic cycles to precise physical geometry. Step 1: 1D Meanline Design (Preliminary Design) Derive the Euler equation yourself
In this stage, the radial variations from the hub to the casing shroud are considered. Designers use streamline curvature methods to optimize blade twist and lean, ensuring uniform aerodynamic loading along the span of the blade. Step 3: 3D Blade Profiling & CFD
