| Abstract: | The characteristics of a radial grooves are analyzed in this paper with a key on theopen force and the liquid film stiffness influenced by the groove shapes with different boundary pressure and different shaft speed. The results shOW that the round bottom groove has thegreatest open force and the greatest liquid film stiffness compared with the cosine groove orthe flat bottom groove. |
