- •
The thermoelastohydrodynamic behaviors of T-grooves gas face seal are studied in theory.
- •
Temperature fields of gas film with thermal effect and elastic deformation considered are calculated.
- •
The influences of heat dissipation and face distortion on seal performances are numerical analyzed.
- •
A convergent gap is formed under low pressure condition, and a divergent gap is formed under high pressure condition.
