Deadline Date: 31 January 2026

Fluid machinery—including pumps, turbines, compressors, and fans—plays a vital role in various engineering applications such as energy, aerospace, water resources, and manufacturing. The design, analysis, and optimization of fluid machinery systems rely increasingly on advanced numerical methods that enable accurate, efficient, and robust simulation of complex flow phenomena such as turbulence, cavitation, multiphase interaction, and fluid–structure interaction.

This special issue aims to provide a platform for researchers and engineers to present recent advances in numerical techniques and their applications in fluid machinery. It invites high-quality original research articles and reviews that explore state-of-the-art methods, emerging trends, and innovative applications in the field.

Topics of interest include, but are not limited to:

• High-fidelity simulation techniques (DNS, LES, DES) in fluid machinery
• Turbulence modeling and validation for rotating and unsteady flows
• Cavitation and multiphase flow modeling in pumps and turbines
• Mesh generation, adaptive meshing, and immersed boundary methods
• Fluid–structure interaction (FSI) and rotor–stator coupling strategies
• Optimization and design of fluid machinery using numerical methods
• Machine learning-assisted numerical simulations
• Reduced-order modeling and surrogate modeling for design applications
• Experimental validation and benchmark datasets for CFD models
• Novel applications of numerical methods in emerging energy systems
