HEC13 Axial Turbine CFD Performance Study

ANSYS Fluent 2026 R1 · Automated MRF Operating-Point Campaign · Interactive Post-Processing

Numerical performance characterization of an axial-flow turbine concept for a marine-energy system. The workflow combines a three-dimensional ANSYS Fluent model with automated PyFluent case execution and browser-based post-processing of torque, shaft power, pressure drop, mass flow, and power coefficient.

Model Overview

Numerical Model

  • ANSYS Fluent 2026 R1, three-dimensional pressure-based solver.
  • Steady Multiple Reference Frame (MRF) treatment of the turbine rotating region.
  • k-omega Shear Stress Transport (SST) turbulence model.
  • Water-flow operating points with automated inlet-velocity and rotor-speed sweeps.
  • Positive X-axis rotor direction selected from a two-direction screening simulation.

Reported Quantities

  • Shaft torque and mechanical shaft power.
  • Tip-speed ratio (TSR).
  • Power coefficient, CP, and torque coefficient, CQ.
  • Inlet-to-outlet pressure drop.
  • Mass-flow rate and operating-point metadata.

Interactive CFD Results

Hover over individual operating points, switch performance metrics, and rotate the three-dimensional operating map. The embedded dashboard is generated directly from the CFD campaign summary files.

Interpretation boundary: This page presents numerical CFD operating points from the current prototype geometry. The quick campaign is intended to identify promising operating regions; it is not a substitute for mesh-independence testing, transient blade-passing analysis, or experimental validation.

Presentation Figures

Static figures are populated automatically by the result-import script. Figures that have not yet been generated remain hidden.

Methods and Limitations

The current study uses a steady MRF approximation, which resolves operating-point behavior without resolving blade-passing transients. Reported performance values should therefore be treated as numerical model outputs for design comparison until supported by additional mesh-convergence work and physical testing.

The public dashboard intentionally exposes derived performance metrics and presentation figures rather than proprietary CAD source files or the complete Fluent case/data package.
