Engineering question

Local component losses, pipe friction and temperature-dependent properties had to be balanced consistently so parts remained comparable in the real system context.

Model & approach

  • Model line sections and connection components with common balance surfaces
  • Combine throughput and temperature states into traceable system characteristics

Boundary conditions

  • Liquid flow with temperature-dependent properties
  • Several line, coupling and operating variants

Results of the assessment

  • Fluid properties and local geometry losses shaped the resistance characteristic together.
  • Systematic balancing exposed which components governed each operating state.

Engineering consequence

The characteristics supported section sizing, component comparison and the pressure-loss budget of the complete circuit.
