Description

When hydrogen being transported through a piping network, some may permeate through the pipe walls. For this challenge you will need to evaluate how much hydrogen permeates from the outer surface at steady-state.

Consider a Eurofer pipe with an outer diameter of 25mm and inner diameter of 20mm at a fixed temperature of 600K. The hydrogen within the pipe is kept at a constant pressure of 50 MPa and the outer surface can be modelled by fixing a recombination coefficient.

📖 Task: Evaluate the hydrogen surface flux from the outer surface of the pipe

💡Hint: consider the type argument when defining the mesh.

import h_transport_materials as htm

# eurofer properties
D_eurofer = htm.diffusivities.filter(material="eurofer_97").filter(author="chen")[0]
S_eurofer = htm.solubilities.filter(material="eurofer_97").filter(author="chen")[0]
Recomb_eurofer = htm.recombination_coeffs.filter(material="steel").filter(
    author="grant"
)[2]

print(f"Diffusivity of Eurofer: \n {D_eurofer}")
print(f"Solubility of Eurofer: \n {S_eurofer}")
print(f"Hydrogen recombination on Eurofer: \n {Recomb_eurofer}")
