Abstract

This paper presents a novel approach through the Meshfree weak-strong method based on radial basis function, to calculate the distribution of dimensionless pressure of T-groove dry gas seal (T-DGS). In order to avoid a singularity and improve the accuracy of results, linear polynomials were added into the radial basis interpolation and described gas film stress of T-DGS in the form of explicit function characterization. The opening force, gas film stiffness and leakage rate were obtained by the Matlab calculation program. Compared with the related literature, the error was less than 5%, indicating the feasibility of the simulation. The systematic simulation was used to analyze the multi-parameters for T-DGS under different working conditions. The results revealed the influence mechanism of the pressure, rotational speed, groove depth, film thickness and groove number on the sealing performance. By means of the 3D distribution diagrams of the sealing dynamic and static pressure, we found that dry gas seal could well adapt to high speed condition and the formation mechanism of dry gas seal opening force.
