Mechanical Response and Parametric Sensitivity Analyses of a Drainage Pipe under Multiphysical Coupling Conditions

Table 3

Sensitivity analysis of turbulent models.

Model	RNG k-ε	SST k-ω
Test-σmax (MPa)	1.48000
FE-σmax (MPa)	1.56000	1.56148
T (h)	5.5	8.8

Note. The FE-σ_max and t were obtained based on the basic parameters mentioned in Section 5.3, without considering groundwater.
