This poster presents advances in geometry modeling techniques aimed at both improving the energy efficiency of volumetric compressors and increasing the precision of contact modeling in railway vehicle dynamics. Rotary volumetric compressors, which consume 15% of all electricity used in industry, are essential to many industrial processes. Leakage flows through rotor gaps have been identified as the main cause of energy losses, and even a minor increase in efficiency can lead to significant energy savings. Mesh generation for twin-screw machines therefore deserves special attention, as it is essential for understanding and controlling leakage flows. The first part of the poster explores various mesh generation techniques tailored to computational fluid dynamics in twin-screw machines, opening up the possibility of design optimization to reduce leakage and improve performance. The second part explores the challenges and solutions of geometry modeling for the wheel–rail contact problem, with the primary emphasis on insights into wheel–rail interaction from a geometry modeling standpoint. We highlight the application of advanced THB-spline techniques, demonstrating their capability to enhance the performance and accuracy of our modeling approach.
